I measured twice, hmmmm.... It's pretty close to a 90 si motor. Some more questons have come to mind since this was posted. If I do go frt. wheel drive and shorted the axles and keep the original frt. susp. will I blow outter cv joints with all that new power? The idea that was most cost effective to me was to cut both axles, the one from my donor motor, and the one from my N600. fuse the two together and retain the outter joint so I could use the original susp. I'm kinda worried that is too much for the outter joints to handle. Also the N600 was air cooled, so I need to put in a rad. which I have no room for. So the rear wheel drive idea sounds better. Anyways, this is kinda what's up in my mind right now. I was entertaining the rear wheel drive idea last sat. when I was working on an NSX, I was looking at how the engine was mounted and how strong the subframe looked. I wonder If I pull this off if any rice magazines would want to take pictures and put it in the magazine, .......
