1991 Camaro RS - Turbo 3.1l Project

I'm sorry I didn't get the chance to really talk to you guys at the m&g. Glad to hear that you are getting the tuning thing down though. It's probably a tire shredder on the 5 pounds lol

Thank you guys I really appreciate it!

Car is running pretty good now, boost is set at 10 psi. My injectors are around 80% duty cycle at WOT, glad I picked up some 48lbs a couple weeks ago. Probably installing those then increasing the boost some more. Car feels somewhere around 230-250 whp, not sure on torque. Hopefully going to get a run on the dyno at my college soon to get some numbers.

[DynoDave]

Nice! Don't go too crazy on the boost.

[C2YT]

Against Dave's better judgement the car is set at 11.5 lbs of boost

Pulls pretty good, no knock, afrs are fantastic. Car is idling much bettter, still a little rich though (14.2). I'm happy to say I have finally got all this tuning figured out. I want to work up the boost to around 15 psi, get a solid tune, and then back it off down to 10 again. Would like to take the car out to milan and see what both tunes run so I have a good idea.

Car is running pretty good, put the 4th gen rear end in. What a world of difference. Solid LCAs and a founders adj panhard bar and the wheel hop disappeared!

[DynoDave]

Excellent!

Does the 4th gen have the Zexel Torsen diff in it?

[C2YT]

I believe it does, but to be honest I had no need to pop off the girdle and check. It was from a 2000 camaro, so it should.

[DynoDave]

Yes, the '98 - '02 LS cars have it. A very robust piece, so you should be good-to-go!

[Atrus]

Didn't some catfish 4th gens have the Auburn, some have the Torsen?

99-02 only

99-02 only

Thank you.

[C2YT]

Well this pile is getting LS swapped. I caved...

Looking for a 4l60e and converter. I just picked up a 4.8 with 120k miles on it complete. Goal is to have it done by next spring and make 450-500 wheel horsepower. The V6 has been a lot of fun but it is time for something new.

[DynoDave]

Wow. That's a change alright.
