Which ebay turbo? Looking to buy one today
 
So for you guys running china turbos, please point me in the right direction. Links, details on your turbo (good or bad), etc etc.

I'm literally driving myself to not care about the car because I cant fucking decide on which one to buy. I have $$$ in my Paypal account right now that's been sitting in limbo for a replacement turbo for weeks on end now.

As long as it bolts in, flanges are straight and not warped to shit, and the compressor side of the turbo matches my existing setup (IC pipes and small enough inlet flange for the air filter), I'm ready to buy one today.

My current Garrett turbo is a .48 compressor and .49 turbine (I'm guessing that makes it a 2848?) Its both coolant and oil fed. And I'll have to have the wg welded shut seeing that I run a EWG.

Please help me out guys. Its so god damn nice out and the car just sits.....and sits. I have the cash and the time to work on it, I just cant get myself to order one! :vash:

I would feel way more comfortable buying from a seller that has proven, working turbos.

I found this one in his store - http://cgi.ebay.com/ebaymotors/Drift...Q5fAccessories

I'm wondering if the one you linked is too big or not.

Anyone else?

buffon01 05-24-2010 07:10 PM

He's had it since his 2554 died. Since then is been pushed to 26psi and ~300whp on a mustang dyno. Before the tubular manifold he was on a begi log making somewhat ~240whp @ 15 psi on a built 1.6. Look up his threads

buffon01 05-24-2010 07:29 PM

I was also interested on this one http://cgi.ebay.com/ebaymotors/T28-T...item2c4f074366

dustinb 05-24-2010 08:24 PM

I have this one:
http://cgi.ebay.ca/gt28-internal-was...item35a97b2532

And am really happy with it. I just posted dyno results here:
https://www.miataturbo.net/dynos-timesheets-21/97-1-8-godspeed-gt28-turbo-%40-11-5psi-47750/

Be warned though, it does come with a 15psi actuator. Yes they say it is a 8psi actuator, but they lie. Found that out when I first took it out. 15psi felt great, but too much for me. I retrofitted a SR20 HKS wastegate on it that is set to 8psi, and just used my boost controller to turn it up. With a big enough exhaust and a proper tune, I'm guessing 15psi would put you at 250hp or so.

jsutto13 05-24-2010 08:32 PM

Someone had a ballbearing 3071R for $600 when I looked a couple days ago. Depends on what your HP and driveability goals are.

buffon01 05-24-2010 10:36 PM

He said the 2870 I initially posted might be a bit too big, I dont think a 3071 for twice the price is of much interest.

latena 05-24-2010 11:53 PM

I think I read somewhere that the godspeed turbos are a decent unit. Don't quote me. I am sure you could google them and see wassup.

Myspeed123 05-25-2010 01:03 AM

CXRacing. Thats what I'm running and I can't complain. A few mod's were needed to install, but nothing you can't figure out.

sixshooter 05-25-2010 07:50 AM

According to the specs that is a 2560 size turbo.

cardriverx 05-25-2010 05:32 PM

Im running a CXracing, working great so far (about 100 miles on it).

Jeff_Ciesielski 05-25-2010 05:37 PM

Another vote for CXRacing, just use a restrictor.

Turbo_4 05-25-2010 07:05 PM

I have this one:
http://cgi.ebay.com/ebaymotors/Drift...Q5fAccessories

I bought mine whenever they were for around 150 or so...I'm not sure whats with the price increase.

Thanks everyone! I think I'm just going to bite the bullet today and order one. :)

I just cant decide on a size. I like how the car was power wise with the Garrett I have on the car now, so I'd ideally like to find something the same size, but it looks like I don't have that option.

Does anyone think going to the bigger turbo will make a huge difference in how the car drives?

My 2871 is just as easy to drive as my 2554 was. Just much much faster.

OK I'm all set! Just ordered the GT2870!

http://cgi.ebay.com/ebaymotors/ws/eB...m=120574646411

Now I'll order all the other shitz I need to get this bar back on the road. I'm fucking paying insurance every month and it just sits!!! :vash:

Thanks again for all the help making the decision! :bigtu:

Phil, did you have to clock anything to make it work? From the pictures it seems that I should be good to go. Shows a side mount manifold and the regular 5 bolt dp flange, just like what I have in the car now.

Now I'm wondering if my existing oil feed/drain setup is going to work. I think it might not actually.

hingstonwm 05-26-2010 02:08 PM

Wow, 300.00 don't break the bank!!!

Seriously there are times that I wish I still had a miata engine in my project car. My turbo alone was 5x the cost of what you putting on. :facepalm:

I am interested to find out what kind of service life you guys are getting out of these chinachargers

More than likely you will need to clock everything so it sits right. But since it's brand new it will be easy. Just loosen all the bolts and spin to correct position. The water and oil drain should be the same. The oil feed fitting will not, IIRC it's a tad bit bigger.

There are chinachargers that have been on people's track cars for years. I see no reason to expect that they wont last as long as garrett journal bearing turbos. I rebuilt my garrett with what i'm sure are chinese parts and its been working flawlessly for 2 years now.

ZX-Tex 05-26-2010 02:39 PM

Subscribed anticipating positive results. Good thread for future chinacharger shoppers.

Man I can't wait until my motor break in period is done. It sucks driving around town trying to stay out of boost.

I'm running the same china 2870. Quality seems good,a dn has a 1yr replacement warranty

Why are you trying to stay out of boost? You should have been beating the shit out of it from the first time you warmed it up and changed the oil. Disconnect the wastegate if it makes you that uncomfortable. Lots of WOT and engine breaking . Profit.

+1 The first twenty minutes should be under high load at varying rpms, but this is a threadjack.

wayne_curr 05-26-2010 07:49 PM

I thought you were suppose to stay out of boost during break in but get it under as much load as possible while not going above 100kpa with lots of engine braking.

Jeff_Ciesielski 05-26-2010 07:52 PM

We should start a new thread.

tronik 05-27-2010 03:08 PM

I have (mostly) the same question as OP, and since he seems to have purchased his, and it would be retarded to open an identical thread, hopefully this isn't a threadjack.

I've been running a greddy (6psi), hacked up Racing mazda downpipe, IC, Bipes, AFPR for 1.5 years or so. This summer I'm going to install my link ecu, rx7 440's, pierburg fuel pump, redo the IC piping cleaner.

While I was at it I decided to change the turbo setup in order to get a watercooled turbo with a little more oomph to it, and get rid of the RM downpipe, which has a secondary o2 bung added at such an angle that it makes my LC-1 sensor rub against the frame from time to time, which recently cost me a sensor.

Anyways, I ordered the cx racing manifold/DP, and now I need a chinacharger to go with.
CX says the manny/dp will fit a mitsubishi t25 16g but are no more specific than that.
best cantidate I could find was this one.
Anyone see a problem with this turbo, or able to point out a better one?

buffon01 05-27-2010 03:19 PM

What's your goal?

If I had a 1.6 I wouldve gone with a t3 combo. They're so cheap is ridiculous.

tronik 05-27-2010 03:22 PM

goal is just a bit over 200 at the wheels. I don't want a ton, ~200 would suit me fine, if they were available in the lower half of the rev band.

I looked at the T3, but I don't have a manifold/downpipe to fit it, either the greddy/rm combo, or the CX manifold/DP

buffon01 05-27-2010 03:28 PM

Tacotaco sells a t3 dp, but for 200whp you dont need it. Just get the t25/t28, with something similar to this specs

inducer 46.5mm/60mm
turbine 53mm

and you got yourself a 2560.

ZX-Tex 05-27-2010 04:27 PM

I have not verified it but if that is the case on the sizing that is a great turbo for troniks goals. I still miss my 2560.

buffon01 05-27-2010 04:42 PM

Those specs are from the Garrett page

That manifold doesn't seem bad at all, any ideas on what downpipe you would use?

tronik 05-27-2010 09:16 PM

ok, I am full of failrage towards myself for not being able to figure this out. I've looked through pretty much every chinacharger ebay offers (HUNDREDS) and I'm still not confident I'm not going to choose something that will definitely fit the CXracing manifold/downpipe. I emailed CXracing yesterday asking them if they sold any turbos that were known to fit. I doubt I'll get a response. (*edit - "For this combination, I don’t know" - not surprised. This was funny though: "We have sold a lot of this manifold + DP sets, no complaints, so they work")

Anyway I think I have one picked out, if someone could do me a favor and check my work.

For reference again, here is the CXracing manifold and downpipe combo I ordered. Their description "Fits 16G Mitsubishi turbo/T25"

But almost all the "T25" chinachargers sold have five bolt downpipe flanges.

Attachment 197238

as can be seen in the pic of the CX downpipe, it's using a 4-bolt flange - probably DSM spec 4-bolt

http://s1.promotionsupplies.com/ebay...u-dp-mx5-3.jpg

The only two Turbos I found that I think have a shot at fitting are the following:

TACOTACO's BIG 16G TURBO TD05 INTERNAL WASTEGATE LANCER EVO 4G63

http://trendgears.com/ebay/TacoTacoN...rbo/4-TD05.jpg

The problem I see with this one is that it isn't identifying it as a T25 anywhere - only as a TD05. I googled a bunch trying to see if it was the same thing. Found several people wondering as well, no really concrete answers. Particularly whether not just the manifold->turbo flange is the same, but whether the turbo->DP flange is the same, and in same place relative to the manifold flange.

The other turbo looks like the closest thing to what I was looking for -

T25 Turbo Charger internal wastegated Mazda Miata MX-5

The only problem I see with this one is that the compressor wheel specs are way off the garrett 2560 specs buffon recommended.

Specs are as follows:

tdo5 - Compressor Wheel .70 A/R Cold Side 12psi spring
Inducer 48.15mm /Exducer 67.82 Trim: 50
Turbine Mitsu Style 4 Bolt Flange ind: 55.85mm Exd: 48.90 mm

t25 - Compressor Wheel 0.60 A/R 7psi spring
Cold Side Inducer 38.74 mm /Exducer 52.20 mm Trim: 55

would that T25 even be an improvement over the greddy mitsu TD04H?

I feel retarded for asking further questions... The intricacies of turbo sizing are not something I know yet, and the wife being due in a week is seriously hampering my research time.

So which (if either) would you purchase to hopefully work with the CX manny/do with no (major) fitment issues?

JerseyKid 05-27-2010 09:50 PM

As far as i know, the T25 DSM turbo's are the only one with a four bolt flange as opposed to the SR20 T25 which is the 5 bolt design.

TonyV 05-27-2010 10:24 PM

Very interesting as I am beginning to search for something myself.
I'm still working on proper sizing for my nearly 2.0L, and seems like 3076 is fitting the bill.

What I'm curious about is if a Tial Vband housing will be compatible with the Chikety China turbos.....might make for a decent setup

ZX-Tex 05-27-2010 10:46 PM

To get dimensions for various flanges, go to the Garrett site, pick a turbo (with the flanges you want to look at), click on it, then click on the flange dimensions link.

interesting...
As per this picture, the manifold I will be using has a round flange too

http://s1.promotionsupplies.com/ebay...u-mf-mx5-1.jpg

that fouls things up for me on the second, "T25" turbo, since from what I can tell based on the auction's crappy pictures, it has a rectangular port, like it should

Attachment 241607

half my confusion picking a turbo for this man/DP may be because I'm a newb with turbo specifications, and perhaps half is because CX doesn't know what the hell they are selling. It's quite possible that the man/dp is meant to fit a TD05-16G and not a "16G Mitsubishi turbo/T25"

buffon01 05-28-2010 12:32 AM

tronik you haz to use mitsu flanged turbo. So 16g, 20g..etc...

The first TD05 you listed is very similar, in specs, to the 2560. I would get that one.

Vashthestampede 05-28-2010 03:37 PM

So....even though this thread went another route, I have another question.

I've always been one to say no gaskets, but that usually leaves me with exhaust leaks once they blow out. :vash:

After doing some searching I'm thinking of going with copper gaskets from SCE. http://www.scegaskets.com/Turbo-and-...orGaskets.html

Does anyone have any thoughts on this?

I would be getting one for the manifold, downpipe, and for the ewg. So roughly $30 for the gaskets isn't bad in my book.

Does anyone happen to know the size of the ewg flange? Everything is still bolted up to the car so I cant check mine to reference it.

No idea on the EWG size, but I've heard nothing but good things about SCE copper gaskets. I'll be using them on my car.

buffon01 05-28-2010 03:54 PM

What about high temperature grease?

Vashthestampede 05-28-2010 04:04 PM

I've used high temp silicone before and had it blow out in less than a days time.

I did some searching and it seems lots of people praise the use of copper gaskets. I actually never heard of them before until I searched "turbo gaskets" about 30 mins ago.

buffon01 05-28-2010 04:06 PM

Not silicone, grease. 18psi did it, and Ive heard from others that it seals very well.

RyanRaduechel 05-31-2010 11:46 PM

Hey Tronik, have you gotten your DP and mani yet? Im curious as to what the actual product looks like, if it is close to the picture...

tronik 06-01-2010 04:37 PM

no not yet. If it's drop shipped from china, it could be awhile, but I have ordered from CX in the past (IC stuff) and gotten it in a reasonable amount of time. Their IC stuff is a big time recommend btw.

I don't expect to be able to use the Man/Dp out of the box even if it looks alright. I plan to weld bracing between the engine flange and the turbo flange, and to make relief cuts on the manifold. The downpipe doesn't cone with a secondary O2 bung, so I will weld one on. if my crappy wire welder can handle all that, anyway. It can on mild steel. Have to hope everything lines up properly..

purchased the TD05 from CXlighting over the weekend. Bigtime thanks to those that weighed in.

Vashthestampede 06-01-2010 04:56 PM

The turbo just came today! I'll upload some pictures after I clean my desk off.

It came in WAY faster than I expected via FedEx, and it was handed to me (not left on the porch in the rain) once I signed for it.

Out of the box it looks as expected and the fins actually spin, unlike my Garrett. :facepalm:

Vashthestampede 06-01-2010 06:29 PM

Pictures! :)

Now I guess I need to take off the wastegate and have that shit welded closed. I also need to order gaskets, some hardware, make sure my coolant and oil lines are good to go, etc. So this probably wont be going on the car until next week, but at least its here! lol

buffon01 06-01-2010 07:14 PM

That is sexy

ZX-Tex 06-01-2010 08:11 PM

Looks good to me! The wastegate arm angle looks a little steep but if you are welding it up anyway no worries.

I love it how Chinese companies selling product to the US feel compelled to put USA, or US, or American, or some US city, or some other reference to the US in the name, even though most know it is from China. Harbor Freight is full of stuff with names like that.

RyanRaduechel 06-01-2010 08:20 PM

Cococarbine3 06-02-2010 03:01 AM

Are Garrett and Ebay turbo parts interchangeable? IE could you hypothetically speaking put an Ebay compressor housing on a Garrett CHRA? Or more specifically, can I put a GT30 .63AR Tial V-band turbine housing on a T3/T4 Ebay Chinacharger?

Pictures indicate it's plausible, but I've looked and haven't found any evidence that the two are compatible sizewise.

buffon01 06-02-2010 10:17 AM

I remember Scott said he was going to try and see if the parts are compatible. Ask him.

NA6C-Guy 06-11-2010 04:57 PM

I would like to confirm that this thing actually has "standard" flanges, not like some ebay turbos I have read about recently on here that use slightly different flanges to really mess your build up. Looks like a steal for $300 shipped.

Would you guys think this thing would be comfortable at 10psi (or whatever would put me in the ~200-220whp range)?
