    Well you could get lower compression pistons, and you could get a thicker headgasket which is the cheapest route.

    lots and lots of oem turbo cars have CR's in the 8's, if you are planning on boosting I always recommend doing up the bottom end before the boost, so you have time for break in, it's much easier to work out any problems such as rings not seating right. And when you add the kit, your peak psi would comply with your engine management, fuel, and tuning, which are all external from the motor itself, of course this is just my opinion.......I am an all motor guy after all.
