I've gotten a lot of feedback that what I was thinking about wouldn't work... but... Anyway, the AFM thing is down, because I'm going to a Motec ems and will use MAP for load. I think its a better measure and a lot faster than any air flow sensor (MAF). I did this conversion (though using a Haltech) on my 3rd gen Rx7 that is one of the more highly modded Rx7's on the street. I got the M3, becuase (a) I had one and loved it and (b) I DIDN't want to turbo or supercahrge. I wanted to spend the money to build the strongest motor for street/track days I could on a normally aspirated basis. I just love the sounds and feel. I am trying to build a motor that will put 250 hp to the ground reliably. I currently am making about 215 rwhp, so I have a ways to go, but it should be do-able. I am close to going with Jim Rowe at Metric Mechanic to upgrade the motor a but (pulsed chamber header, 13:1 cr, extremely light flywheel/clutch and smaller throttle bodies.) . That's why I was wondering if some sort of Vanos/Vtec could be cobbled into the motor to widen the torque curve. I fiugure, you never know. The bores on the M50 or some Honda motor might have the same spacing as the S14? Maybe there was some way to adapt it? I know that the high rpm range lobes are fairly aggressive, so I thought it wouldn't hurt the top end power, if it would work at all. I don;t have a clue how close the front cover is or anything else.
