turboing my 2000 miata...
 

ok so im gathering parts for my build its going to be stock internals shouldnt be a problem since my car only has 40,000 miles on it in my eyes its still a practically brand new engine lol

so my question is! is there anything special i need to look at while getting ready to turbo the car?
i was on miata.net and that wasnt very helpfull i kept getting heckled for no reason so i gave up on that site...

im running a t25 turbo and building my own exhaust manifold, i co-own a custom harley davison shop here in ohio with my father so i have all the tools you can think of and know-how to get it done...

plan to run a SAFC-II but got told to buy a MS and no one would explain to my what they considered to be a MS???

do i need to run bigger injectors and fuel pump?

anyone else with some help please throw it out please no smart ass comments or anything like that this is my first miata and im just trying to learn and figure things out !

my car as when i first picked it from the guy in kentucky im now in Cleveland, OH area..

MS is a megasquirt if you didnt know... it's a standalone ECU, it's definatly the best, cost efficient way to run your newly boosted engine.

wether or not you need new injectors is up to you, it depends on your power goal. thats where you should start, decide how much power you want to make. go from there.



oh, and read the DIY FAQ sticky

I am by no means anywhere close to being an authority on this and compared to the knowledge on this board I know very little.

However I am just finishing up my turbo build on my 2000.

I hear great things about using the MS. I have an older Link ECU system. Any standalone ECUs are gonna be $$$ and the MS is completely customizable and cost wise a darn good deal.

I don't know what kind of power you want to make, but your stock fuel pump should be OK to about 260ish H/P. My system uses added injectors along with the stock ones but these guys know what you will need to add for injectors etc. Mine runs an auxiliary fuel rail with 4 additional injectors added to the factory.

Your manifold and down piping will be pretty intense to get right. One it is very tight to configure and two making it last. There happens to be a manifold and downpipe here for sale that may be a way better way to go as far as bolt-up and go. Can't remember what turbo it is for but trust me one of the biggest PIAs I encountered was the whole exhaust/downpiping configuration. Don't forget that it is way easier to do on a stand but WAY WAY different when you are actually trying to make it work in the frame of the car.

Also the inner frame rail may need to be notched to accommodate your set-up. Not sure how you will trial fit this without physically putting it in, measure,check, remove etc.

Mine was EXTREMELY close.

Turbo cooling and oil return lines. Again mock-up with all accessories. Lot of trial fitting and routing there. And I have already learned this with just a few hours use. I used rubber lines with heatfoil wrap. It won't last long. Go with braided stainless. Mine will need to be replaced with braided soon enough.

Don't know what if any you will run for inter-cooler. But again there is a TON of time spent with routing and clearances.

Everything you do routinely will be a lot more difficult after all of this is installed. I had to tighten up my alternator blet after run-up. Took a LOT longer because you have to de-pipe to get clearance to simple things now.

Oh yeah and you will be cutting belly pans etc. Take your time there.

Basically you need to plan on this taking a LOT of time. You need patience, think it all thru and learn to look past what you do to one part may cause an issue with another.

It was a challenge to do mine, but in the end most of the challenge came from having to become familiar with what will cause you problems because your car is new to you.

After finishing mine I can do it again in a 1/3 of the time and do about 5 things completely different than I did.

Be prepared to be without your car for transportation for awhile for this. Once it is in work, you are pretty committed at that point.

I have been working on cars and own High Tech motorcycles that I also work on myself so skill wise I am not a newbie. However you will still find your skills challaged in this.

Good luck and I will be happy to help with anything specific I can for you. I still have un-healed knuckles and hands that I can tell you EXACTLY where they happened from this build. All fresh on my mind......LOL

thanks man i have a couple friends who have turbo'd a miata or two before im just trying to get a grasp on this myself so i can help more then hinder ive been trying to figure this out without being heckled trying to figure out if i need specific parts i havent found anyone using an safc-II just people using AEM ECU's and MS...has anyone tried using the SAFC-II with some views?

SAFC is worthless. Don't even bother looking further into it.

What do the harley guys think about buying a custom bike from a guy who drives a girly car?

omfg

Take that SAFC and insert it firmly into you ass, then once nature has taken its course, sell it on craigslist.

The SAFC is completely useless, all it does is modify the voltage from the AFM in order to change fueling. Unfortunately it also effects timing at the same time.
Its unpredictable and dangerous. It has no place on a turbo miata.

Actually, I just remembered an SAFC wont even work on a 2000. The NB Miatas use a hall sensor instead of a traditional cam angle sensor, and the afc/safc/neo/etc is not able to read the output from the hall sensor. So the engine will not run.
So, ditch the fucking SAFC, its a peice of shit, its useless, and anybody who uses one is an idiot who doesnt know shit about EMS/tuning/etc.

DO NOT EVEN THINK ABOUT NOTCHING YOUR FRAME RAIL. I have seen disgusting pics of hack job frame rails due to shitty setups, and there is no need to do it. If your turbo doesn't fit, then you need to buy or design a different setup to make it fit.
Your stock fuel pump will be fine, as will your stock injectors up to about 7psi.
You can run stock injectors to about 7psi using a voo-doo box, anything past your stock injector requirements will require a good FMU to control timing and everything else, I.E. Megasquirt, DIYPNP, or a parallel Adaptronic.

Also, that fake non functional roll bar behind your seats won't work with a turbo application, so you need to remove it.

Read the FAQ. It is all there.

And welcome.

i have read this and no offense but some one just coming into the miata world this means nothing talking about MS and Link ECU's and what not means nothing to people unless they can find useful information on them ive gone through their forums and sorry but the write ups mean nothing unless you're already in the world i know honda's and DSM i understand turbo'ing them but miata's are a completely different animal in their own league so i have started to understand the MS and i will be getting one instead of the SAFC for sure especially since it WONT work with my car...

i think ill be running RX7 injectors most likely...

No offense, but quite a few of us turboed our cars off those FAQs. If you don't understand something, google it until you do. The pieces will eventually fall into place and you'll be better equipped to troubleshoot and make improvements if you fully understand the system you put together.

like i said im starting to understand A LOT more! im looking for a megasquirt-II as we speak! will this work with my 2000-LS 5spd 1.8L miata ?

Yes sir, it will.

Look in the stickies in the Miata parts for sale section for Braineak's thread on selling MegaSquirts that he builds. They are a good deal and he has built MANY for forum members.

im trying to save up some money to finish up buying my MS now!!! lol im thinking ill be running 550 or 650 rx7 injectors...

my next question is can some one show me or explain to me the whole GM air temp sensor install or whatever it is??? i see this and just not sure where it installs too

First of all, you sound like a 14 year old girl texting her friends...2nd, the gm iat gets installed in the intake piping, I prefer to put it about 6" from the throttle body. That way you get a precise measurement of what your intake temps are before it enters the engine. 3rd, the only injectors you will need are 550's. I prefer the rx-7 pnp's cause you can score em pretty cheap. 4th and final, the megasquirt is a not really beginner user friendly unit to work with. Find out as much as you can about it before you make a costly mistake. I suggest buying a diypnp unit from braineack. Good luck with your build, and keep this in mind...as long as you listen and learn, me and other members will be more than happy to help. I.E. Don't be a douche, cause we'll all tell you to go f yourself.

not being a dick or anything but where do you get off saying i sound like a 14yr old girl texting her friends? second ive never acted like a douche towards anyone so im trying to figure out where you're coming from with all this ???

The 14 year old girl part came from where you were like "lol I think ill be running...". I just didn't see the humor in the injector size, so what was the "lol" about? I also never said you acted like a douche, I just said don't be one if you want help. No need to get all riled up for nothing.

sorry but no offense you coming in here telling my not to act like a douche bag then contradicting yourself and attacking me saying i sound like a 14 yr old girl word to mouth you attack me then tell me not to act like a dbag? practice what you preach

How about I practice this..You are a new guy. I was once a new guy too and I learned way more than I thought I already knew. You need to worry more about learning and reading about other members mistakes. I'm just trying to give you the edge and save you many headaches and lots of time and money.

sorry but your post have nothing to do with saving money the only thing you said was run 550 injectors after that you were thread bashing! so i have read i understand that the MS system is not for beginners and is not to be taken lightly! hence why i am asking about the all this stuff in MY thread hence the reason people post THREADS on here TO LEARN im hear reading and asking questions so please unless you're helping dont post on my threads i asking a specific question all i need is a specific answer not a smart ass response this isnt just to you but to all that feel the need to come in and thread bash

Well thanks for not singleing me out...I guess. No thread bashing intended, if you have a question, I'm here to help.

ok thats all i ask im not some smart ass punk here just thinking of doing this im already in the works im already buying parts and what not so that was my question can you point me in the right direction of where to find out about the GM ats or the IAT as you called it?

Go to diyautotune.com and you can find the gm iat on there. I used a steel bung not an aluminum so I could weld it to my intake pipe. Depending what setup you use, you can snip the stock iat pigtail off and solder or splice ( I recommend solder) the gm iat pigtail on. If you would like photos I would be happy to provide.

pictures would be great!

When I get home I'll fix you up...give me like 45 minutes?

no problem im in no big hurry i havent bought the megasquirt or anything so im just like i said doing reading and figuring out which parts im going to need and what not?

can you also inform me what other custom things i might need i have the turbo,exhaust manifold,blow off valve,boost controller, interfooler+ piping,down pipe, wideband, ordering the MS...im just not sure what im missing custom wise besides the IAT...? im trying to make as much as possible by myself...and im kinda doing a poorman's build...i know i sound like a cheap ass but its what im working with right now...

The homoeroticism is palpable

really??? can we get a mod in here to ban this guy??? im in a build thread and this tool comes in here saying that the gayness is easily seen?

did you have to google "homoeroticism" and "palpable"? :laugh:

I was referring to youre little one sided bitch fight with 'thirdgen'.
Maybe you should actually listen to advice when you asked for it, instead of getting all defensive.
If it wasnt for us you would be trying to hook up an SAFC right now and wondering why you cant even get your car to start.

how about you read it all!!! him and i are over all that bs and then you come in here starting some bullshit drama seriously

mod please get rid of this guy!

and yes i did take the advice numb nuts!!! hence why im buying a MS!!! and not a SAFC-II!!! read on dumbass READ ON!

Yah, Im the dumb one here :facepalm:

: Pantiesinaknot:

seriously??? ok ill start coming into your threads

Thanks, I would appreciate the input. Have a great day.

Have a great day,

Mike

Well now...45 minutes after I post from my iphone, which I hate posting from...and I get home to this bullshit? What would I say in a pardiciment like this?...I guess I would do it as if I was face to face with someone, which would go something like this...
"Listen you Fucking ChinBall Wizard...my patience with you is ice skating...ice skating on thin fucking ice that is...I mean you give me shit about calling out a doucher when in reality all I am doing is trying to help you from making the same mistakes as I did, as we basically have the EXACT same car. You single only me out, even though other members said valuable informative things like, "MS is a megasquirt if you didnt know... it's a standalone ECU, it's definatly the best, cost efficient way to run your newly boosted engine", "What do the harley guys think about buying a custom bike from a guy who drives a girly car?", "omfg
Take that SAFC and insert it firmly into you ass, then once nature has taken its course, sell it on craigslist."
Aside from the anger...here's a pic of a GM IAT mounted where I believe it should be on my '99...and sorry for bein all agro, but remember, you can't just jump in the ring with ALI cause you think you box. Full Tilt Boogie...1,107 posts as of this thread...senior member...maybe for a reason? As for the OP, I should change my avatar to "Word to Your Mother", cause fuck all this bickering. If my car was faster than yours than F you, and if you said "how do I make my car that fast?" I'd gladly say, "here's how, but you MUST listen to EVERYTHING I have to say." Here's a lesson on opinions, cause BTW, I HATE harley's, cause only ------s that fill out credit applications ride em.
Attachment 15907

really man i came at you asking questions nicely the bickering was over till the other 2 stepped in hence why im getting pissed all im doing is asking questions to make sure i get shit right and thank you for the picture!

:bowrofl:
I love you man
*no-homo*

Lol, welcome to mt.net

Don't take anything too seriously on this forum. It is the internet after all.

Good luck with your build!

btw none of the harleys i build/ work on are new they're shovel-heads and evo's all carb'd not fuel injected

Someone please put this in the FAQ

To reply to #42...
Yeah well I don't care what they are...if they support East Coast choppers than their homo's. There's a saying, and it goes something like this, "build it so YOU can fix it." My grandfather owned a 1939 Harley Knucklehead since 1942? He knows nothing about it other than how to ride it, which is pretty bad assed since it's suicide shift. Fuck all that though, I bought a '78 Triumph Bonneville 750 that people said was "worth money" and the day I got it home I sawzalled the tail section off and 2 weeks later there was a TIG welded hardtail on it. NO Rear suspension, jockey shift, and wait...what else??? electric start???? That's for pussies who watch the discovery channel, it's KICK START only on these 2 wheels...Needless to say I turned it into most likely the most badassed Triumph creation in PA, and when people say "why would you F up the originality of that bike? It would be worth so much more?" I say..."Oh yeah? to who, cause to me, it's priceless"...same goes with a turbo miata. I could get book value for my '99, or I could make it smoke Z06 vettes all day long. Is it worth $6,000?..maybe, but when it beats a $32,000 car, it's worth the satisfaction.

Don't buy anything until you've spent 6 months familiarizing yourself with all of the different aspects of the possible arrangements and their benefits or drawbacks. If done properly, it will involve much use of the search button at the top of this page and reading through sometimes initially unrelated threads that distill into morsels of useful information. There are years of trial and error and accompanying advice from thousands of contributors and sources. Every question you have asked had been posed and resolved thoroughly and repeatedly such that our elder members can become weary of the questions. They see it as a sign of laziness when newcomers ask to be spoon fed. They treat those noobs less than graciously as an offhanded way of dissuading this behavior. As was once simply stated regarding this forum, "We are a helpful bunch, but we will not spoon feed you."

As one who has been there, there are three ways to proceed from this point. You may study and learn with the help of the forum and its tens of thousands of pages of resources, proceed against the grain and become more deeply frustrated, or acquire a complete kit from a reputable manufacturer and have someone tune it for you. I chose the first. Most that remain here did as well. The ones who chose the second option often leave without the information they seek. And many of the ones that choose the last option either don't need us or don't want to be bothered understanding how everything works beyond the ignition switch and the throttle pedal.

Most importantly, don't peragrate your build without proper time invested in study or regret will be your constant companion.

Most of us are quite friendly and very gracious, but tire quickly of the deluge of noobs every week requesting we regurgitate pages of data on demand. This is one reason you have been treated harshly by some. They also see it as an affront when sentences aren't begun with capital letters and ended with punctuation of some sort. It is seen as a sign of disrespect to the forum. Do not feel unwelcome, but instead feel a renewed understanding for the value the members place on the sanctity of our forum and its etiquette and decorum. Their remarks to you are to them as shooing a fly from their potato salad.

Good luck with your quest for enlightenment and your subsequent construction.

sorry to say but i will be turbo'ing the car i am not going against the grain but going with the flow and learning fast im not one to sit back and have people talk shit just because im not "buying from sponsors!" its annoying as hell! seriously because i dont go with everyone else and the way they have done stuff not being a dick but there is "more than one way to skin a cat" im reading im taking advice from the members and im sorry that the search tab is useless when you dont know what you're searching for hence one member says GM air temp sensor the other calls it a IAT sorry i dont put 2 and 2 together

i bought my PLX M-300 wideband today and im working my ass off on bikes to pay for my MS

Most of the people on here are running DIY turbo setups, so I have no fucking idea what you are talking about.

Also, if you dont know (or cant easily figure out) what an IAT sensor is, you shouldnt be modifying cars. Sorry.

i know what a IAT is i just didnt know if you "MIATA GUYS" had different acro's for stuff shit

You callin me gay boy?
We dont take kindly to talk like that in these parts

Chill out if i learned at least ONE thing from this forum it is to lurk, read, and keep your head down. Tons of good quality information come through here all the time. The only reason people will flame you is because they have dealt with more douchebags than their are numbers in Pi(π), Its not a personal attack its a defense mechanism and a damn good one at that. But no ones here to bust just your balls they are more than willing to point you in the right direction. I suggest you check out the build threads to you can learn alot of dos and donts in there plus plenty of purty pictures.


P.s everyone here is pretty gay so thats just something you'll have to get used to.

I've read most of your posts and feel for you. Sometimes it feels like the natives are a bit harsh.

I think with a better punctuation/grammar/spelling, a tad more humility, and not stooping to the senior haters levels, you'll do fine.

Most people here would help out with answers and steer you in proven directions. If you post up that you bought something or want to try something out that we don't approve of for some reason, feel free to ask why the hate? Trying to save a couple hundred bucks that'll lead you down a path of frustration and future $$$ wasted is sometimes not worth learning from your mistakes. Sometimes these mistakes are very costly.

I'm totally for saving some money, but I asked around, was directed towards someone that had some great reviews, and chose it. Overall, I'm extremely pleased I didn't try to pioneer anything nor try to wrench anything on my own. If you feel comfy working on wiring, engine management, fitment, etc., then by all means go for it. I personally think that unless you're pretty familiar w/ the past failures of these guys, you're starting blind and are a good candidate for expensive "whoopsies".

Anyhoo, good luck and please use a period (".") when appropriate. Your thoughts convey a lot better and doesn't turn us off from helping.
