I'm preparing to rebuild a 6 bolt and use it inside my 2g. So far the setups on Jackson Auto Machine are what I'm aiming for, the Stage 2 motor and Stage 3 head setups in particular. My only question left (so far after loads of research) is in regards to the differences of 8.5:1 and 9.1:1 compression ratios. My plan is to basically hold the horsepower at 550-600 until we get used to driving it, then open it up to 700-750hp. I'd like to only change the boost setup and retune the ecu accordingly to make the jump in hp. Can I build this motor at 9.1:1 and still throw enough boost at it to accomplish this? Or should I keep it at 8.5:1? I just like the idea of a little more giddy-up off the line with the 9.1:1, but with needing to receive more boost to make the final hp mark I'm also understanding in the need to lower the compression. Any comments are appreciated.
