I just bought a b18a1 block at a junkyard. My question is what head would be best for me? a b16 or a gsr? i plan on mabey turboing the engine later after i put the engine in. i hear a gsr is better for turbo. also if i were to bore it out to 2.0L and sleeve the block. what kind of pistons would i need and what else would I need to go along with the new block? and would it be fairly east to make 200+ hp with the lsvetc? Thank you!
