Re: boosting a 12:1 gsr motor
obviously a thicker headgasket will lower the compression, however the difference between 12:1 and 11.5:1 with boost is pretty negligable, I would try to get it down to 10:1 max for a pump gas engine, a bad tank of gas and that engines going boom at 11.5:1

he is better off replacing the pistons to something lower than 10:1 or it will have to be detuned to the point that it will probably not work well at all and run the risk of damaging something.
