eBay turbo kits
 
We kind of started to have this conversation over at m.net but it seemed to fizzle. But there's one thing that bugs me over all else concerning the various turbo kits that we see advertized on eBay, and it has to do with completeness.

First off, we're going to acknowledge that there are many different eBay sellers advertizing what appear to be several different kits. At a minimum, I've seen a couple of different manifold styles. Second, this isn't about quality. We're going to play Devil's Advocate and assume that the quality of all of the pieces in these kits are at least sufficient to survive the process of being installed and used for at least a day without immediately falling apart, cracking, or exploding.

Rather, this is about liability. Specifically, what liability, if any, the seller of such a kit has for damage caused to the engine by the purchaser.

We'll take this one for starters:
http://www.boostedmiata.com/FAQ/ebay_kits/miata2.jpg


The above kit actually appears to be more or less complete. It has a manifold, a turbo, a downpipe, some oil lines, and some intake tubing. It also includes a fuel pressure regulator of some sort. Looks like the customer is on his own for an air filter and compressor intake, but apart from that it actually seems workable.


Then we've got this interesting piece of work:
http://www.boostedmiata.com/FAQ/ebay_kits/second.jpg

It claims to be a "bolt-on", and yet clearly that a somewhat liberal interpretation. We've got a manifold, a turbo, a downpipe (ironically one of the better-looking I've seen on an eBay kit, at least from a design concept standpoint), an oil feed (no return) and nothing else. Ok, so maybe truth-in-advertizing is a bit lacking, but I don't see a lot of damage happening to the customer's engine. Without any kind of intake plumbing, the engine would not stay running long enough for the fact that all the oil is gushing out the bottom of the turbo to do any serious damage.

In all seriousness though, the worst I can see happening with this one is an angry post from a noob that says "plz tell me what parts i need to buy to make this complete i bought this turbo kit on ebay and i need help to get the car running because my dad says i need to get the car out of the driveway lolz", followed ten minutes later by: "why wont anybody help me with this im serious and ive built like ten turbo cars be4 so why is everyone being such a dick lol just kidding but seriously can u pleeze post links with everything i need to get and my budget is 300 to make this all work"


Then, we've got my personal favorite, and the one that really irks me worst of all: http://www.boostedmiata.com/FAQ/ebay_kits/third.jpg

The problem with this kit is that a person probably could install it all on the engine and start it up. The intake piping actually looks like it would more or less fit, and while there's no downpipe included a clever person could probably hack something into place. All in all, this one would seem to be a winner- it looks almost totally complete, and heck, it even includes an MBC.

Problem is that there's no fuel control. No AFPR, nothing. A person might reasonably be expected to install this thing on his engine, turn the key, and actually have it start and run. And then as soon as the owner got into boost (and we can make some Serious Boozt with that "JDM'S Manual Turbo Boost Controller !! with Easy to adjust from 1-30PSI") then the engine will go very lean and pretty much destroy itself immediately.


So what do you guys think? Does stating "professional install highly recommend" in the listing absolve the seller of all liability for what happens after Jimmy the Newb blows up his engine by running 18:1 AFR at 15PSI with no ignition retard? More to the point, has anyone ever actually seen or heard of this happening?

Yes. A guy I know did this to his 240. Bought an ebay kit that was pretty complete except there was no fuel management. Ironically, he drove it at 5PSI for about 3 weeks. Then he turned it up to 15PSI. Well, yea first time he gassed it threw some rods, broke pistons, etc. Car hasn't moved on it's own power since. I still don't know how it survived with 5PSI and no fuel management for 3 weeks. I literally looked at it and told the guy he should stay out of boost till he gets it fixed, and he left boosting through 1st and 2nd.

It would be interesting to hear from someone with a background in some kind of law. I mean, if you buy a part at autozone and it fucks up your car, you would think that they would be liable. When those firestone tires were exploding, were they liable for that?

Joe Perez 04-07-2008 09:44 PM

Well, what was the outcome? Did the 240 owner attempt to seek recourse against the seller, and if so, what was the nature of their interaction?


Originally Posted by wes65

I don't think that's a good analogy.

Assume I go into Autozone and say "I would like to purchase an oil filter for my 1992 Mazda Miata." The person behind the counter then sells me an oil filter. I install it on the car, and while driving down the road the next day, the filter bursts, causing the failure of my engine.

Assuming that the clerk used the parts catalog to find the specified filter for a '92 Miata and sold me the correct filter for my car, then Autotone likely has no liability- they were not in any way negligent in conducting the normal business of selling an oil filter which the manufacturer of the filter has stated is suitable for a '92 Miata. My recourse is against the manufacturer of the filter. The only ways I can think of in which Autozone would have any liability in this case would be if:
1- It could be proven that Autozone had prior knowledge of a likely problem with the filter, such as a manufacturer's recall notice, an observed history of failures of that particular model filter, or
2- If the filter was physically damaged or defective in a way which should have been obvious to a person whose job duties involve the selling of oil filters.

Let's say however that the parts clerk was out of the "correct" filter, so instead they gave me one with the same thread and basic dimensions, but spec'd for a Honda instead. Or perhaps Autozone's computerized database contained an incorrect cross-reference for oil filters for a '92 Miata. In this case, Autozone is likely to be liable for my loss since they misrepresented the suitability of the filter for the purpose of being installed on a Miata. It does not matter if the misrepresentation was intentional (the Honda substitution) or unintentional (the database error). Autozone is in the business of selling car parts, and they have a responsibility to sell the correct part(s) for a given application.

The eBay turbo kit is more like this last example. With regard to the third kit which I posted:

The one thing I don't see on that particular ad is an explicit statement that the kit is "complete" or ready to "bolt on". In fact, the seller states "All of turbo parts and accessories do need to modification in order to fits perfectly. otherwise will list ABOVE." I think that's hustlerese for "Everything in this kit will require modification to fit unless we say otherwise."

It would be up to a claimant to demonstrate that the seller had somehow represented that the kit, by itself and without the addition (not modification) of parts, was complete and suitable for use on an otherwise stock '94-'02 Miata. This is clearly not the case as no fuel management is provided, but you'd have to prove that the seller both (i) had an obligation to disclose this fact, and (ii) that they failed to do so. This failure need not be deliberate or malicious- it would be sufficient to prove that a seller of turbo kits has a reasonable obligation to either provide a complete kit or to specifically advise the purchaser what is necessary to make the kit complete.


Still, there are things you gotta love about that ad. Such as:
http://trendgears.com/ebay/HMTLMIRAGE/dot.gif JDM'S T25/T28 Turbo Downpipe Elbow
http://trendgears.com/ebay/HMTLMIRAGE/dot.gif Made out of High quality of Aluminium Material
http://trendgears.com/ebay/HMTLMIRAGE/dot.gif Made from 100% SUS T-304 Stainless Steel
Well, which one is it?

patsmx5 04-07-2008 09:50 PM

No, he never tried to fight them. He new he needed a RRFPR, but he was dumb. He figured it was more for adding HP then adding fuel to save the engine.

mazda/nissan 04-08-2008 11:17 AM

i could only see it as a legal problem if someone were retarded enough to think that it would fit, but i guess patsmx5 proved that. However, would the seller try to pull an autozone and say that they are just a distributer, and that they don't make the parts but they were told it was a direct bolt on with all of goodies?

93inNM 04-08-2008 11:28 AM

Hey Joe.

Assuming that these 'kits' are functional is probably a misnomer but I DO get why you started with that assummption.

Probably the greatest error in wanting POWER is understanding the WHOLE picture. People more often than not think a complete kit of some kind is all that is needed. Many do not do their homework, look at all the angles of what they need, just install some kit and think all has been covered. Getting them to comprehend the entire picture is moot if they have no clue about any of it from the start other than the kit mentality.

Maybe this needs addressed from the 'what do you need' checklist type of thinking? When you read articles in magazines that may show the 'do it yourself' kit install, most all of them only cover the kit itself and never discuss all the other aspects of needs beyond the kit. This begins the flaw, and unfortunately leads to the destruction of a perfectly good engine or other drivetrain parts.

The day of understanding the basics and BUILDING something is long gone. Just another place where thinking has been eliminated from the process and getting something you can 'quick' install has replaced the process. It is too bad that most want to bypass the basics and understand things, just the gratification side seems to be their goals.

I know a couple people who installed kits, not sure where they got them, but they didn't look at the fuel side and did have disasterous results. One just bought a crate engine and moved on to get it right, the other went the long route and rebuilt the engine. Both did learn from their experiences, but the second guy is now much more competent at everything he does because of the rebuilding process and what he learned. He has since built a really great system and is much better off as a result.

93inNM 04-08-2008 01:04 PM

I forgot to add, in my earlier reply - turbocharging, supercharging, power enhancements in general are not plug-n-play like the things so many are used to these days, not an excuse for not taking the time to learn and do something right. Many buy this stuff with little to no understanding of what they are getting into. Those who take the time to investigate their needs will get it right without much incident. Those who do not take the time will eventually get it right, may be more time consuming, and certainly more costly. The latter group will get the lesson - doing it right, spending what is needed to get it right - there are no shortcuts.


musanovic.

While I certainly DO agree with your assessment of FISHFARTS post, we all must realize that sometimes a person lacks a good vocabulary or the correct communication skills, so this IS their language or means of communication. Not an excuse, but certainly an explination.

Having said all that, there are times when the language that was used is totally correct for the situation . . this was not the time, place or situation.

Take a minute and look at my first 'newbie' post where I said GREETINGS to all as an opener to introduce myself. You will see something similar. It made me wonder if I wanted to be a member of the site, or if I should just move on. I decided to continue to participate here, hoping that what contribution I made would be in the best interest of the question being asked and that there would be those who could answer any of my questions with straightforward competent answers. As I said in that post, neewbie to site, not newbie to turbocharging, am newbie to some of the wonderful things that have come about for our cars since the stone age era began regarding turbocharging and I install my first one.

magnamx-5 04-08-2008 01:41 PM

Joe i have always been of the opinion that you buy off ebay and you are on your own. Yes most of those kits are not PnP but they are workable to some extent, and generally come through with cheap ebay turbos. The liability of the sellers is a moot point as far as i am concerened, noobs can come here and read our posts etc, and be able to figure it out. If they cant then well maybe they shouldn't be messing with there car to that extent alone. Just my 2 cents though being a ebay turbo purchaser and general noob to everything turbo before i started on my miata.

devin mac 04-08-2008 01:55 PM

eh, unless the ad says something to the effect of "you don't need anything else to install this shit and run 275hp" you'd have a hard time selling "it's their fault my car blew the fuck up" to ANYONE, let alone a jury of people with half a brain combined.

that said, fucking retards that spill hot coffee in their laps somehow got money from McD's, etc...

That's part of the problem- the ones we see advertized on eBay typically are not, however there certainly are enough that are to muddy the waters for some folks I'm sure.

The kits that FM, Bell, and Greddy supply are most certainly "plug-n-play", at least insofar as that no additional parts are required. The Greddy kit has no tuning at all to speak of, and the Bell and FM kits are sufficiently baselined as to work without blowing anything up. Ditto the various superchargers kits from Moss/JR/FFS...

It's largely a hypothetical question, a thought-exercise if you will. I was curious to hear the real-world experiences of others and how, if at all, they corresponded to my theories...

mike_671 04-10-2008 11:29 AM

This should be a sticky.

93inNM 04-10-2008 11:43 AM

I agree - this should be a sticky, or something similar that does tell it like it is.

Back in 2000 when I decided to turbocharge my car, I took the time to read everything I could find to fully understand what was needed to do things right. I did not want to blow up my engine or have any headaches from an insufficient amount of knowledge.

There are some great books, lots of info on the net, really NO excuse not to get it done right with all the right stuff. Someone in a hurry or someone who llacks the understanding, well, they probably eserve what happens.

Serper3 04-14-2008 04:53 AM

I think no matter what is done, people will still buy these kits because of the great deal they think they are getting as well as the constant image being portrayed of being able to buy everything dirt cheap on eBay. When I saw these eBay kits for sale, the first thing I did was look up as much info as possible to see how these kits worked out.
I think if people get these kits, its their own fault for any damage because if you are trying to turbo your car and didn’t do the research, you’re the only person to blame. On the other hand, they should be more specific saying something like other parts required or, hardware kit.. etc.

Joe, great idea for a thread... but one piece of advice. The eBay ad's you're linking will be gone in a month or two. The links will only go to a page that says "Sorry, this ad is no longer active" and people won't be able to see anything. Could I suggest taking screenshots of each of the popular ebay turbo kits and a short paragraph on each one... for example, this kit is probably the most popular one out there that looks like it has everything, but we all know it's crap. Just a paragraph highlighting it's strengths and weaknesses as a kit compared against the other kits would be of great service to noobs looking for info.

Braineack 04-17-2008 09:24 AM

there sam, happy?

Joe Perez 04-17-2008 12:37 PM

Actually, I downloaded a complete copy of all three postings- images and all, in html form. If someone can give me a place to host them, we can change the links.

jwheless23 04-26-2008 04:21 PM

hey fella's im new to the tuner game and want to say i have alot of respect for yall guys who know what ur doin because i don't and am trying to learn. i just bought a white 91 miata 40k miles. im very interested in turboing it and doin it right. what is the best way to do this without blowing a wad because i am a student but i do understand that i can't cheap on it like those cheap ebay kits.

cjernigan 04-26-2008 04:29 PM

Go to the blue link in my signature.

HKSturboMiata 06-03-2008 02:39 PM

They all say

*note: as you may know these are after market parts. We recommend professional installation.

So they can just say the user did not know what he was doing. Also I saw one that said 90d warranty LOL!!!!!

flier129 06-17-2008 01:32 PM

Was reading in the may/june issue of Project Car tuner mag about their white 91 'Project Lap'. They got the car to compete at their annual Super Lap Battle event. They found the 91 B package WITH a hardtop for 2400k at a local salvation army.

First they did a full 5zigen exhaust, and a k&n filter which got them to 103.41 whp and 92.66tq. Then they put in a Spec clutch/flywheel combo, then suspension goodies RB sways and endlinks, some braces, EBC rotors/pads, tokico springs and shocks (wha? y not flex or stance or..... something?) and SS lines. They also put a wings west kit, which looks pretty damn good imo but i cant justify the cost of that vs money spent on better turbo parts.

So the point im getting at, they ended up buying a Godspeed project turbo kit off ebay :(. The first sentence of this write-up includes the words 'our miata has brought us more headaches than any other build thus far' . Along with a walbro fuel pump and a custom FMIC tuned with an AEM F/IC on 91 octane they got 168.4whp and 158.6 ft-lbs.

From my months of reading on these forums and a few others those numbers are fairly weak. If you were to put the cost vs power gains itd probly be....... well terrible. They were trying to show viewers that you didnt need to spend the money on the prefabbed kits to get the wanted results, they admitted that the cost actually added up to be up over any name-brand kit (ouch). Could of easily got a JRSC for 2200 without manage and been at 175rwhp :(

Anyone else read about this?

samnavy 06-17-2008 03:50 PM

I have said this several times before.
PCM is the worst thing to happen to the tuner industry since neon windshield wipers.

The extent of the writeups show you how to install CAI's and Catbacks (which usually come with fairly good directions). Then they fill the rest of the magazine by spending a shit-ton of money on some old beater and all it ends up looking like is some old beater somebody spent way to much money on. When they do have the opportunity to do something correct, like build a decent turbo Miata for under $10k, they go out of their way to make horrible purchasing decisions and don't even bother to justify it. It's a terrible rag.

About 6 months ago, just before the Miata thing came out, I sent them a very detailed and constructive 2-page letter about how I though they could improve the quality and legitimacy. I sent links to about a dozen internet threads I found that absolutely trash the mag and they all say the same thing... lame articles that provide absolutely no benefit to 90% of car-nuts. When the second Miata article came out, I sent another letter (referencing the first) about how this particular build emphasizes exactly what I was talking about in the first letter. I specifically said that anybody who currently owns a turbo Miata and reads this article will instantly think your mag is nothing more than a parts advertisement for whatever company you're trying to promote that week. Who the fuck spends $1200 on a naturally aspirated miata exhaust? 5Zigen... I'd never even heard of them. And I can't imagine other communities will think differently when you rape over their cars either. I haven't heard back.

flier129 06-17-2008 10:40 PM

well i'd have to completely agree with you samnavy haha. kinda puts me at ease to know i wasnt the only one thinking that way :).

a mag with a god knows what budget is hard to compare to someone like me on a student budget. i think ima stick to mags that have write-ups about a guy doing the work in his garage, part after part with his money, then getting good enough results to get noted in such a magazine. thats my opinion anyways. i'd have to say out all the forums i read daily ive learned the most off this one :-D

Saahild 07-12-2008 02:18 PM

So from what I understand it, as long as you are not a total idiot and just bolt this on and hope for the best, and you use a decent engine management system with it you should be fine?

The problem I can see from what you guys have said is that they advertise as plug and play but they do require engine management of some sort as well to sort out fuel and spark.

An ebay turbo kit with a megasquirt for example would be a decent budget system?

I may have missed something though but does that sound like a reasonable conclusion?

It would be a great budget system... for about a month when the turbo fails and the manifold cracks.


Search ebay turbo kits, there are other threads on this.

Matt Cramer 07-21-2008 08:25 AM

Recently I emailed a seller of one of the more complete looking eBay turbo kits (what can I say, I was bored) and asked if they had a compressor map for the turbo. Much to my astonishment, they answered within a day, but said, "Sorry, we don't have the compressor map; you'll have to determine that for yourself." And no, they hadn't confused a compressor map with a fuel map!

Saahild 07-21-2008 09:40 AM

Asked them if they have had any problems with manifolds cracking or if they have any pictures of any vehicles they have fitted this to. Not yet I am afraid, and there are other parts needed to complete the kit. Not the most promising of answers there. Nice in theory but not so much in practice.

Saml01 07-21-2008 10:01 AM

Your never gonna sue somebody on ebay for a turbo kit that blew up your engine. People who buy em, buy them on their head. If they screw up its not the kit makers fault, because you will never prove it was their kit that was responsible, they will have an easier time proving your ignorance.

Same way that if you buy Bells or FM's kit and blow up your engine, youre not gonna sue them either. Furthermore, youre not gonna sue Tom if his shitty PC Pro blows up your engine, he will claim it works in his shop and you fucked up installing it, and its not his problem.

Very sad, but indeed completely true :mad:
fortunately companies like fm and begi have a reputation to uphold, and strive to put out a good product, and when something goes to shit, try their best to help out or fix the problem. Ebay sellers dont give a shit, if they get enough negative feedback, they just make a new account and keep on sellin. that is the difference

No.

Imagine how much money these china makers will make if they start selling none important shiny parts, such as a cheap, polished valve covers

Saahild 07-26-2008 06:16 AM

That was the kit I saw, It does need an oil return line but the rest of it is complete according to that ebayer. But no idea what the quality of the components are tbh.

Yah, totally complete except for just one thing...

Oh yah, and a downpipe, oil feed line, water lines, water and oil line fittings, NOTHING FOR FUEL, NOTHING FOR TIMING, no boost gauge, no vaccum lines for anything, no gaskets, no intake pipng or filter, no clamps for the piping, no mounting hardware for the IC... except for those things just bolt it on and drive away.

Slacker and Saahild, you have just re-emphasized the need on this website to haze NOOBs who don't do any homework on their own before asking lame-ass questions. It's pretty clear neither of you know what exactly would come in a "complete" kit in the first place or theres no way you two would have asked that question or posted that response.

For an example of a "complete" kit, just go to the BEGi or FM site and look at their parts list.

Saahild 07-26-2008 11:45 AM

Um guys read the whole post... I did say ACCORDING TO THE EBAYER!!!!!! And you screw at me for not reading...

All i stated was that was the ebay kit I saw that provoked me to post in the first instance. And after reading through this thread and others I was under the impression that there are some "complete" kits out there that, if used with proper engine and fueling management, would be a decent budget system. This was corrected by a member off here telling me that the quality would be tat and the manifold and or the turbo will break in a month or so. Previously to this I had emailed this ebayer of this kit and he had come back with what was required to complete this kit. I pointed this out to Slacker here in my post adding that this is what I had been told by this ebayer. Also added that the quality is suspect. Don't see anything wrong in what I posted. Please do explain what was wrong with what I said.

Its missing the following:
Compressor outlet and inlet adapters, note how the seller forced a silicon connector into the 3 bolt flange on the turbo.
piping and intake filter
intercooler will not fit if you have AC, unless you want to move things around
oil feed lines, oil return and flange.
Injectors, fuel and ignition controller or a full set of bandaids.
the rest of the downpipe.
The intercooler system is probably not a bolt on, modification will be required.

Overall, a new begi manifold is ~$400 + ~$250 for a Good T25 + $200 for a proper intercooler and piping from ebay + an ebay $30 BOV will build you a better kit then that.

He didn't mention anything about IC clamps, or fuel management, or a downpipe... anything like that? Do those things come in his kit only he doesn't include pictures or any mention of them in the ad? That's very nice of the eBay seller to do that. Most eBay sellers just tell you a complete line of bullshit so you'll buy what they have. Most eBay sellers will lie straight to your face to get you to buy what they have. Very strange.

Well they did go very quiet when I asked if they had had complaints of manifold or turbo failure so yeah. Buyer beware of cheap ebay tat. Btw just out of interest is there a comprehensive list of parts out there for a turbo kit? Did read through the FAQ and it does answer a lot of questions and I am sure a list could be pieced together from the contents of this thread but a comprehensive list of components would make a great sticky.

BTW I thought that the fuel/ignition management was just understood so wouldn't need to be mentioned, We had discussed downpipes in a previous email so was not mentioned and again I would have thought obvious enough not to need mentioning and finally to be entirely honest I have no idea what an IC clamp is but I assume it is some sort of bracket to hold the IC in place but he did not say that these were needed. Again after he was not willing to comment on the reliability of his product I swiftly moved away from the idea of an ebay turbo kit. Rather drawn towards the EDT (i think) 1.8 greddy manifold to use the greddy kit on a 1.8 with a nice megasquirt. Or if I find a comprehensive list of parts then I may even make one of my own using a premade good quality manifold and collect up the parts as a little project.

I didn't read it, I just saw the pretty pictures. I wanted to get to you first before you got banned. Read that, from the MsPaint-work I saw on some of those pics, I am led to believe that it will tell you how a turbo works, and what part does what. Of course you could google (but then again, maybe you can't) or look on wikipedia and see what parts do what in a turbo, and what you would need.

I know, I know, you'd like someone to list exactly what parts (including part numbers) you'd need to turbo your miata. Alright, if that's what you need, here that will probably be your best bet.


(edit: funny, I got ragged on in another thread about having a Honda. I used the website that the dude referred to to find this info. Call it a hunch, but I thought, just maybe, if there are eight million retards turboing hondas, there's got to be easy to follow instructions. Well, I was right. Fuck, I still haven't nor will I ever read that whole post, but damn, scrolling through it I saw a metric-fuck-ton of information being spoon fed. It's a four cylinder, just turned the wrong way.)

Yes, it all clamps in perfectly, every piece is custom sized and bent for a perfect fit on any Miata '90-'05. I know this for a fact.

If you'll read the ad, the seller says:
NOTE: All of turbo parts and accessories do need to modification in order to fits perfectly.
But don't pay any attention to that. The seller is lying. It all fits perfectly from the start, trust me. An eBay seller couldn't sell you something that didn't fit, they're just being modest. The pieces are all top quality and you should buy that kit right now!!!

Ok, I've done some heavy pruning to get this thread back on topic. If your post was one of the 30 or so that were deleted, don't get all butt-hurt and start complaining. I simply nuked everything that was written after the flame war started.

Here's some good empirical data from a user at Miata.net who recently had a welded T3 log-style S/S manifold fail pretty severely:

EDIT: some further info from the owner of this manifold.

Wow. The manifold lasted less than 1,000 miles before developing the first crack. Even my Greddy manifold, which historically has had a reputation for being extremely crack-prone, is still running fine after nearly 4 years and close to 10,000 miles.

i know stainless isnt the best for a turbo manni.. anyways, would it be a good or bad idea to buy this kit, and eventually replace the turbo with a legit turbo down the road?

How about you go to page 1 of this thread, start reading and answer your own damn dumbass question.

Then make an intro thread, then start reading and stop posting w/o doing so.

Should bolt up. No modification needed.

Yes, it will work just fine, 100%. I bought two kits and I run both of them on my Miata it's a TT system

Yes.

You need to add T-bolt hose clamps. They are obviously not listed or pictured.

This would certainly depend on your goals. Would your future plans involve running more than around 100Kpa of intake pressure?

And what do you think a "legit turbo" you would change to later would be?

You have given me precious little information on which to base my answer.

dgmorr 03-22-2010 01:35 PM

I was always curious why there's a whole for sale section of eBay turbo kits if we're all opposed to them? Is it just for forum sponsorship?

Yah, stainless steel is the worst material for turbo manifolds. Aluminum works much better.
If youre really baller you will cast your turbo mani out of cement

so with only 8 pounds you dont need any type of hose clamp? Just the couplers holding the charge pipes together?

I'm sorry guy, but have you even read through this entire thread? Just reading the very first post where three different turbo kits are discussed, and the parts they come with, will tell you if the kit is going to work for you or not.

In all honesty, given the questions you are asking, you'd be way better off buying a used turbo setup from someone here.

And please read through the DIY faq. It'll answer a lot of the questions you are going to have.

Can we ban this fruit cake yet?

Joe Perez 03-22-2010 03:15 PM

Judging from the pictures and description, it appears to be missing a downpipe, all of the pre-compressor intake plumbing, oil and water lines, and anything resembling fuel or ignition management.

But hey, turbo not hit block!
