I need to know if i can use the OBD 0 ECU in my 5th gen hatch when i get my b20 swap in. I can get a B18a Head, ECU, and intake mani, and injectors for around $150. i want to know if i can put this head on a b20b block. will i need a different ECU, can i use the stock one from my 5th gen(non-VTEC), or can i get one reprogrammed? thanks a lot.
