I've finally got most of my parts and will start assembling my B18A in the next 2 weeks.

1990 B18A
P30 pistons(should be around 11:1)
B18B head, ported & polished, 3 angle valve job, new springs, etc
Crane #12 cams
The usual I/H/E

Question, I've heard that one of the things that caused the 1990-1991 B18a's to be only 130 hp instead of 140 was the IM..

Should I run my stock IM, or get it PnP, too, or get an aftermarket one? Suggestions welcome!!

Anyone care to wager what kind of HP/Trq I'll be making?

Thanks,
Haggar
