    I have a H22a4 and I want run with a turbo 22psi, type S piston will resist or I'll should buy forged piston ? I use eagle connecting rod.

    CP pistons or JE pistons are better?

    type s pistons = 11:1 compression

    11:1 compression plus 22 psi = FUCKING BOOM!!!

    H22 sleeves plus forged pistons = fucked up cylinder walls...

    22 psi = your block needs sleeves and forged 8.5:1 compression pistons...

    Yeah, I'd say the type s piston will resist, it'll resist right through your fucking block. If you do try running 22 psi on a cast high compression piston, PLEASE videotape it for posterity so we can warn other noobs what happens when they don't :search:
