If you install shorter pistons for a less comp. rate, can you make your engine a non-interferance engine? because i read on a couple of threads that that the GTS has a 10:1 comp rate that meens that its to high for FI.

Ive been curious about this. Why is it that most raise the C/R when going SDS stage 2 or 3. All my conventional turbo wisdom tells me that I should lower C/R to compansate for the extra boost, but its different with the SDS, why? CAN you run a stage 2 or 3 SDS with a lower C/R, say 8:8:1 or so?
