Stock (10.6 to 1) compression - 9.8 psi at 9000 rpm on the dragstrip, 8.5 on the street. 27000 miles and keeps on tickin'.
Octane, timing and tuning has a lot to do with how long a high compression motor will last on boost. I run 94octane in mine since day one. When it detonates, it's too much!!
I agree with Erik, fuel, fuel, fuel (in the proper ratio ofcourse)
