you probably dont need my help, or even want it for that matter, but its worth saying...

you should probably consider going mid/low 8s on compression with over 20 PSI... relative atmospheric pressure is at 14.7 PSI at sea level, so an NA motor pulls 14.7 PSI into the cylinders itself... if you run a turbo at 14.7 PSI, you are doubling the intake, your 2.0 will flow 4.0 liters of air, and even with stand alone EMS's you will have troubles with pre detonation and knock retardation with that high of a compression ratio... 8.0-8.8 is the best area for forced induction motors, most guys running big T-77s and T-88s are pushing way past 20 PSI, and their compression levels are low, in the 8s...

pre det and knock retardation is a fvckin pain in the ass dude, do it right, dont screw with it when its put together...

with that said, if you have personally witnessed the exact style motor you are building, and i mean witness not youtubed, and its got 100k on it, then by all means, run the 9.3.... if you are seeing guys running 8.0 or 8.5 ect, you might want to re think things a bit... too much boost in too high compression will split that block like a fir round....
