Prelude conversion FWD to RWD?

Well first off you would have to get a different motor/ combo, like a F20C/F22C from a S2000, then you would need a custom drivetrain fabricated for the rear differential, axle housing, and a custom tunnel would have to but cut and made in the center of the car which means custom rear seats made, and a custom center console, then the issue of electrical and engine wiring would be an absolute nightmare, also the seats might have to be changed due to the width and clearance for the center tunnel, an exhaust would also be needed to be custom made s the factory one sits where the driveshaft goes, you will have issues with the steering column where it enters the engine bay as far as clearance. So after all is said and done you can expect about $25,000-$40,000 in parts, labor, and fabrication.
