I would suggest you take it to a shop with the equipment to do a compression/leak down test and get some accurate numbers. Im an all motor guy myself, but from what Ive learned watching my brother build a 350hp H23 turbo prelude you want some where around 9.5:1 compression ratio if you want to run anything above 7psi. Those ceramic coated pistons sound ideal for forced induction/ possible NO2 application. MSRP numbers for the JRSC are $2595, where as a greddy turbo kit is $3,249.00. Obviously the turbo would be my prefernce if I wanted to run anything above the 6psi the JRSC gives you out of the box. I know you can go up to about 12psi with the JRSC, however at that point its pretty much just as expensive if not a little more than the greddy kit. I would say right now you need to figure out what your working with on the bottom end of your motor. The link at the bottom has some dyno plots with JRSC and boltons...hope this helps.
