hi i am looking to give my 1988 sse some better performance and a better and quicker throttle response... can anyone tell me what i need or how i can do this.. and also i would like to no if there is a way to make my tranny shift faster so i can hit higher speeds faster... thanks

Honestly..there aren't many performance mods for your year.

My best suggestion would be to lighten up the car a bit from all the audio that you have in your sig. There is surely enough weight there to make a difference.

If you are willing to do research, The austriallians (spelling) have made performance parts for the LN3 ( I belive they call it the Ecotec 3.8 "don't quote me on that" ) You can find some interesting parts there.
