What Compression should i get

[airjordan56]

I am getting my block rebuilt and I was wondering what type of pistons i should use. My mechanic is planning on putting 11 : 1 compression pistions in my car, but wouldn't that be too much compression if i bolt up a turbo or run nitrous? Any advice would be greatly appreciated

you need to figure out what you're gonna do before you choose,you can run a turbo on high compression pistons,but you will be limited to running a low amount of boost. you can spray nitrous with high compression pistons,however.. if you don't know simple things like this, i reccomend you stay far away from the bottle.
