I'm not a whiz with pistons so you have to bear with me on this one. If I get a wiseco piston for my TB how much more hp will i get? How much more speed will I get? When they say for example .20 or .40 what exactly does that mean? Will I get more hp that way? Please help I'm looking for that little boost. Thanks for any advice and help. P.S. I'm only looking at Wiseco and NO other companies. Also let me know if you've had good or bad experiences.

 

I dont have an answer yet. but i just picked up my wiseco piston for my 2000 trailblazer. Im boring myn .20 over. from what i have heard you dont want to go to much. because of the air cooled will make it heat up alot easer.

 

Ok I know a little more about pistons with the help of my friend across the street. If I just get the stock bore size piston do you think I'll see any difference over stock? If not I'll just go to .20 over. How many cc's will it add, and how much hp will it add? Thanks.
