i just got my b18a block today im so happy
Incorrect, there are 2 diff types of the b18a1, the obd0 and the obd1. The obd1 b18a makes 140 hp, 2 hp shy of the b18b and the b18b's ignition curves are more advanced so you're only an ecu away from that extra 2hp. The obd0 b18a1 has weaker cams. Thx for playing tho
