Re: (CiViC SiR)
dish pistons lower compression ratio which will slow you down. if its a street car limit your compression ratio to 11 to 1 if you don't mind running 94 octane all the time or 10.5 to 1 if you wanna get by with 92 or 91. nitrous doen't affect compression ratio as with a turbo. the only thing to worry about is your cylinder pressure. forged pistons are obviously a must for any shot over 80. srp is a good street piston due to the 10 percent silicone in it allowing it to expand faster. je is the race piston and does not have any silicone in it. so it takes longer to expand but is stronger. assuming its a street car and u don't mind premium gas.. srp pistons with an 11 to 1 ratio works perfectly..
