hey guys, i'm building my 89HF to use primarily at track days. right now i just have a stock 1st gen b16 with intake and exhaust. i'm looking to get some more power out of the engine but i need some advice about which route to take.
the first thing i'm doing for sure is upgrading to obd 1 and getting a chipped ecu. but after that i'm either getting a b18c block or getting some cams and valve springs. which one will give me more bang for my buck? which is more important to upgrade..the head or the bottom end?
