Compression
 

How many psi of boost do u think a stock bottom end can handle with a 2mm thick head gasket, csue I am redoing my motors, I blew out a couple rings and the head gasket and I was gonna put stock ---- back in except for the head gasket, how much do u think that would be able to handle?

Re:Compression
 

while u got the motor apart build it up a little, rods and pistons??? other wise, i'd say 200. I dont think compression has a lot to do with how much the car can handle. Rather lower compression decreases the chance of detonation.
