hey guys I am looking to do the turbo from cobalt proformance aka this one: http://www.cobaltperformanceparts.co...roducts_id=417

except im gunna build it on my own to save me alittle cash.. by bending the piping and stuff

And I was wonderin g who all makes the parts for this because "larger than stock injectors" is kinda bland.. what kind and how big do i need them...

This is what it says but I kinda want to know all of the specifics:

Garrett® GT2860RS Turbocharger
Cast turbo manifold
Cast down pipe
Gaskets and fasteners
Oil and water lines
Attachment hardware
Charge air cooler
Charge air cooler plumbing
Hardware
Engine Control Unit
Larger-than-Stock Fuel Injectors
Garrett Brand Boost Gauge

Your probably better off buying the kit to be honest. Lot less headache and comes with tuning and has been tested. Without the tuning your going to be pretty much dead in the water.

sick06cobalt

well what im looing to do is buy part of the kit and do all the piping my self

NJHK

You are basically talking about going custom.

You're better off buying the parts seperately from this kit.

Just understand you're putting all the R & D in your hands, especially, the piping part and fuel management part unless your'e going to try to get the SCT flash.

Do you have enough understanding on how to build a turbo kit properly?

rick1217

unless you have had experience in the past with turbos, etc..... I would just buy the kit, It might seem like more money, but in the long run, it might just save you money....plus it will be a learning experience for you. just my 2 cents.....
Good luck!!

sick06cobalt

I have a buddy helpin me with it... he knows more about it than i do

NJHK

Do you or him know how to weld?

Do you or him know how to tap the oil pan properly?

sick06cobalt

never mind ive decided im gunna buy the kit when i got the money

just because ill pay for the research the people have put into the kit

NJHK

That may be a good idea honestly because you don't want to get over your head...I've done the custom route on a L61 and it's pretty involved.

sick06cobalt

well thanks guys +1 rep to you guys for helping

wait hold on one more question

would this kit fit?

I'm not 100% the difference exterior of the engine between your vehicle and a cavalier but I'd imagine that space might be different slightly and maybe in how they route the piping.

Just buy the kit that was designed for your vehicle

sick06cobalt

i dont know what kind of gains i would expect

sick06cobalt

okay ive been reading on some stuff and on kits and it says manual transmission only... if i have an auto should i even consider doing this

NJHK

It won't fit your vehicle properly

sick06cobalt

okay so i guess no turbo for me...

adam isnt the MT only thing just for the alpha kit.

I think all the piping would still be good and ofcourse the turbo and all the rest, its jut your tune.

If im not mistaken SCT almost or does have a tune thats available for the 2.2 auto's. You could buy garrets GT tuner kit, which is everything but the tune, and try for the sct tune or use a piggy back on low boost, so as to not hurt the engine.

And if i sound like i dont know what im talking about, I dont, Ive just been researching and **** for a long time and it seems to me like what i said is right, oh and the fact im dead tired and its 2:30 in the morning, so if any of that was wrong please correct me

NJHK

I don't really follow the kits but if a kit says manuals only, it's saying that because of fitment issues and difference in routing because of the transmission.

They usually advertise what transmission they support.

This isn't saying that you could never turbocharge your automatic

Just that a kit that says "manual only" won't fit yours.

Moza13-

what about alpine? They were in R&D last time i heard on an auto

NJHK

Yeah, I believe I remember seeing the same thing

If that's the case, then it will fit.

sick06cobalt

but what about tuning? am i screwed or what

Moza13-

alpine has a piggy back tune with their turbo kit. Its safe to use under low boost pressures as far as i understand. But SCT i think may have a tune or will have a tune for auto soon or maybe now

NJHK

What Moza said, you can use piggybacks and be fine.

Read up on O2 Sensor Clamping and that'll help you some.

I can point you to a little read about it if you want...

sick06cobalt

sure why not
