oh i cant believe "forgot" hah only kidding, i was waiting for someone to ask the relaible question.
this is my weekend car
its an 89 turbo grand prix (factory) that has extensive work done to it, and it asl 5-speed swapped with the getrag 284. this car has seen more abuse than any of the cars on this forum , I can almost gaurentee that.
the 5-speeds (284s) WILL TAKE ANYTHING you throw at it, 2nd gear dumps at 5500rpms, launching under 25psi, ya it does well. (has non vacuum brakes- electronic so can launch under boost)
396 whp @ 8psi
