I have a 2003 Cavalier with a 2.2 Ecotec of course. I found a really good deal on a stage one turbo from a friend of mine and came up with a few questions that I figured I could turn to you people with. First of all let me start by saying this I blew the ever so indestructible ecotec motor once and being that i work for chevy was the only reason they replaced it. It costed the dealership 5700 bucks to fix my motor and will cost me more the next time. So as you can see I'm not trying to blow it again. So I'm gonna do this the right way. Now before I do forced induction...My question to you is what ALL should be done to the motor first and in what order should I do it in? I really hope all of j-body fanatics can help me out here! I need it!!!

you don't HAVE to do anything to the motor really...you just have to run a low amount of boost.
GO PATS!!!
Well like Sparks was hinting at, it all depends on the amount of boost you're going to run. What numbers are you trying to reach? What numbers do you plan to run? What fuel mods do you have in mind? Are you sure you have a complete kit? Where did he get the kit? Oh, one more question, how on earth did you blow the Eco?
Blown.
what psi you run its strongly recommened that you upgrade your fuel system. bigger fuel pump, injectors, fmu, etc...
sorry, i tend to give partial answers quite often...
GO PATS!!!
Hold on you work for GM, why not talk to one of the techs.

Because they dont know jack @!#$in @!#$ about "hooking up" an ecotec they just know how to fix 'em. Plus they all think I'm retarded for hooking up a cavalier so they all talk to me like a mental patient.

Welcome to the world of J-bodies, haha. Anyway, on topic, what is the kit that you're getting? Is it from a specific company? Are you sure the kit will bolt on without heavy modification? Are you sure you have everything you'll need to boost? What fuel mods do you have? What numbers do you plan on running?
Blown.
My question is how did you blow it? What went wrong?
I think people mistake that the ECOTEC is some new undestructable motor that god himself sent to GM...it isn't. It's a well engineered motor but every motor has it's limits on stock internals.
If you want to "help" insure to have a lasting motor, you should do the Pistons & Rods. Notice I said help. There isn't a guarantee that your motor will last forever and you can throw ever damn thing at it and it won't break or you won't experience any problems, because there is always the possibility. Not trying to wish you bad luck but just giving you somewhat of an reality check. You could have forged internals but if you're not sending enough fuel and detonate, that could be it for your motor.
If you need any further ECOTEC help, just ask.

The kit is not actually a whole kit I should mention that..but I will be buying all the @!#$ anyway so... yeah it's a Hahn Racecraft Stage 1 turbo kit. Yes the kit will bolt on...without heavy mods...not sure. I have been told of someone who knows someone who knows someone that has an ecotec with a stage 2 from Hahn and stock internals stock clutch and drag radials and is doing fine runnin 12's...how true that is?!?!?dunno. But that's my question though if I go inside the engine deep into the internal parts and start ripping @!#$ off...where should I start...what should I do then..and then...and then...and so on and so forth. what fuel mods do I need? how bout this question:
the 2002ecotec came with a bigger fuel rail and bigger fuel injectors would they work for a turbo? or should I go bigger? i dont know the size of them but I do know they are bigger than 2003+up ecotecs.
and as far as number's I haven't figure that out yet...I just wanna hook it up and have fun doing it. I live my car and I feel she deserves to breath (so I'm going to FORCE her to...lol..)

Very true. I believe he's maintaining a 12.9 or 12.8 1/4 mile time. His name is Hypsy on here.

Well, like you said, you want a turbo kit. Do your turbo setup first then see where your next goal is whether it's horsepower or 1/4 mile times, find your goal. If you see that you won't be able to reach that point without going pass (or getting damn close to) your stock internals limitations, then open up your motor to do internal work. The best thing for you to do is to upgrade your Pistons, bearings and Rods. These parts probably take the most abuse as far as boost goes, so it's best to get stronger parts to handle that amount of power.

what fuel mods do I need?
Fuel Injectors, Inline or Intank Fuel Pump and some type of Fuel Management setup whether it's a piggyback, standalone or FMU.

No, you shouldn't use their injectors. I'm not sure how true is as far as them being "bigger", but that's a negative on using them for boost. You have different options on injectors to go with. As far as size goes, that's somewhat up to you, how much power you plan on pushing etc etc. When you figure this out, you can contact Karo @ www.carcustoms.net and he can order you whatever size injectors you need or you can find yourself some Ford Green Top Injectors which are 440 CC Injectors (which is what I plan on using).

Sounds like a good idea. You don't want to get too high of expectations and plan to do a bunch of modifications when you might be comfortable with just a turbo kit itself.
If you have further questions...ask away.

Well said, Adam.
I'd like to add that you should choose your fuel mods carefully. If you have the time and money you should invest in the Megasquirt system. You'll need a laptop, a wideband oxygen sensor (something you should have regardless of the setup you run), and alot of time. It will take some time to figure out how to use MS but its the best choice for our OBDII computers.
If you're new to boost (like me), which you probably are, then look into simpler systems for now, unless you have the time and money to spend on the aforementioned MS. FMU's (fuel management unit) and AFPR's (adjustable fuel pressure regulator) are something you should look into.
Hahn is a good company and you're getting some quality stuff (that is if it hasn't been abused by the previous owner).
Blown.

the kit has never been installed...he ordered a stage 2 kit and they sent him a stage 1 he was "supposed" to sent it back....yeah well they sent the stage 2 b4 he did so he said @!#$ it and kept it!
