ok guys a buddy of mine wants to build a b20z vtec turbo.. He has got the block its 84.5 mm its has a block guard installed and he wants to boost it to 275-350 hp.. its going to have a forge piston and rod combo arp rod bolts head studs the basics then a pretty simple build for the head like a b16 head type r cams.. now ik 84.5 is pushing it but to friends of mine have done similar builds and had lots of luck with them.. now my question what would be the best cp ratio for boost ? i mean i will drive it na for a bit and enjoy na then boost in the future so i was thinking 10.1
