Ummmm. I've heard of 200+ whp D series motors. And not with drag kits either. That's with the greddy kit. As for the B16, that puts down 134 and 98 to the wheels (99 Si numbers). 4-5 psi greddy D's hit 140 and 140. You'd be school'd by the turbo D. My only gripe against this is the platform. Your rods are toothpicks and would snap in a matter of months. Also the head... To be effective, at least snatch up a DX head. Other than that, GO D SERIES!
