Well, I figured out what was wrong with my d15B1. 1 of the exhaust valves had a quarter of it missing. So I went to junkyard and pulled a head off of a B2. My friend told me if I got the head and ECU, it is about a 20hp upgrade. Only, I think it is slower. I even swapped the ECU's a few times and there is no difference. What's the deal...is this kid BSing me???
