hi im dave, i just bought a 96 ssei. fully loaded. it has 147k and i absolutely love this car. this was a upgrade from my 94 grand prix with 180k (got into accident...thank god). im looking for performance parts. i know of insense and zzp. im looking for a exhaust system. i know alot about the series 2 engines my friend on niaoa is doing a l67 top swap on his impala and ive been helping him. i know i need to do the 180 deg t-stat and colder plugs. and i have a few questions. what is the top speed limiter? and where can i find a upgraded pcm. intense has them for 97 and up. oh, and when i swap pulleys down to the 3.5 should i go presson or modular?
