ok i did a little lokking around and found a thread that dealt with the internals and stuff.I guess i should of done that 1st. Ok now i have a new question that i couldnt find a thread on. What the compression for the pistons on a 2000 cavy 2200(2.2l) at and when i get new pistons what would be the best compression i should keep them at for boosting? and to add 1 more thing how can i change the gear ratio in my tranny(auto)?
