Engine Swap - 1997 Cavalier RS 2.2L
To get a higher compression ratio you can do one of three things.Get domed pistons with valve recesses,mill the block or the easiest mill the head.Take a few thousandths off the head at a REPUTABLE machine shop and bolt it up but make damn good and sure your valves will clear the pistons while at TDC (Top Dead Center) before you mill that head and check after it's milled with the head torqued down,otherwise you'll do all that work only to destroy ALL of the valves AND pistons!Boring it out will ONLY add to your displacement ie. CID/CC/L maybe from 2.2 to 2.3 or so depending on wether or not you go .030 or .060 over if it will handle it.Then larger pistons and rings to match.That will help with the HP pluss mill the head to get 10:1 compression and run 93 octance and she'll purr nicely.Throw in a header,a good exhaust,highflow cat and muffler,knock off the AC compressor,cold air intake and she'll be top notch.Don't know if they make roller rockers for these or not.It really all depends on how far you want to go with it.Hope it helped and good luck boss!!!
