alright, i currently have a b18b, and ive got the money to buy nice parts for it.
i was thinking cams since i already have the pistons.
question is, should i buy cams and all that jazz OR should i spend $450 to buy a clean gsr head thats ready for a b18b bottom end?

you guys tell me.

 

gsr head ftw... make sure u get the oil pump too since the vtec head will require more oil

 

alright, would i need to get a diff ecu?
and would my car being obd0 be a problem?
and lastly, would i need a tune?

 

Can't go LS/VTEC without a VTEC head. In the FAQ, there should be a list of parts needed for an LS/VTEC. Go from there.

 

there is a thread about this somewhere let me find it
