I have a 2002 Cavalier with the Ecotec and I am currently installing the Hahn Racecraft Stage II Turbo kit. I want to raise the computer limits on it to take more advantage of the turbo and I was wondering if the ECU from a Cobalt SS would connnect to my Ecotec. Would the connections fit and everything jive?
Won't work. Totally different computer. The Cobalt is more electronically controlled than the cavalier...example: we have mechanical throttle bodies, they have electronic throttle bodies.
When you say raise the computer limits, what are you trying to do exactly?

Raise the rev limiter and governor settings
Even with a turbo kit, unless your motor is built (valvetrain work) ready to rev higher than the stock limiter, you're not going to gain any power.
But if you must know, the new HP Tuners device allows you to raise it and get rid of the governor.

I have rebuilt the engine with Eagle Rods, Wiseco Pistons, and a Patriot Stage II Cylinder head. Once the turbo is on I plan on putting a new side exhaust on it and maybe MSD ignition. I'm not sure if those are the mods you are talking about, but that is what I have done thus far.

I was mainly referring to Valvetrain upgrade but if you have the Patriot Head (which I also have) than you should be fine. Did you upgrade your camshafts?

No, I read that the stock cams are good for up to 400HP. But if you have suggestions I am open to them.

You can run them up to 400 HP but that doesn't meant that you can't get a better camshaft profile for your application.

Comp Cams sells all types of camshafts for the ECOTEC motor, even a set of so called "Forced Induction" camshafts. Contact them for their camshaft specs.

What type of specs should I be looking for?
What qualities would a desireable set of cams for my application have?
