Vtec, the b16 i was referring to was the b16 out of the Skunk2 booklet/mag i got from the skunk2 rep at nopi nats. last year. If i can get my scanner to work ill snap a pic and post it. They may have been lieing of course but it said it was b16 race engine.. Im sure they could have been running race fuel. Oh and out of curiousity are you still running the Busa itb's on your motor? If so what kind of power increase are you seeing from them?
