DPFI vs MPFI also.

The B18A1 has always used MPFI. The extra power probably came from different cams, different exhaust manifold, better fuel and ignition management, etc.
Whoops- he's talking LS. Sorry, brain fart. I thought he was talking about Civic engines, and I couldn't for the life of me figure out where he was getting a 12 hp difference from.
