In response to In response to 37

          

If you are blowing the motor(ring lands) at anything under 8 psi, then its your tuning to blame(fuel system). Running lean on these motors under boost causes detonation. Detonation is the uncontrolled burn of the A/F mixture. The tip of the mix at the spark plug ignites, then suddenly, the bottom of the mix ignites, resulting in VERY high pressures inside the cylinder. This cracks the piston's ring land(the metal "edge" that supports the ring). I blew mine at 11.5 psi. I was running plenty of fuel. Either the spark timing was too great for that psi and stock comression ratio, or it was just too much power for cast pistons. Never heard any detonation. Keep it at 8 psi or less, with proper tuning and maintence, and you will be just fine. As Dino said, getting boost happy, and craving more, gets you into debt, real fast. You will see
