I have a 1999 usdm civic SI. I have 60 k miles on it. I was running 8lbs of boost on factory internals. Its a DRAG GEN III kit. I blew my piston rings in two cylinders. I need to rebuild and was thinking of going with JE forged pistons 9:1 compression and eagle rods. My goal is 12-15 lbs of boost. I would also get a blockguard. Do I need to re sleeve the block or anything else like that? Thanks for your help
