been pondering this for a few years now and wondering if anyone has reversed the rotation of their engines, or aware of how to do it.

 

< thought we were talking about wheels and became confused. Are you thinking of F20C and FWD?

 

either way?

pre 01 (ccw>CW) Post 01 (cw>CCW)

 

the camshaft is the primary piece requiring redesign.

however the timing belt/chain tensioner system would be a major flaw/fail point



i can't help but to ask......why?

 

engineering student, i like to think

 

so custom camshaft, maybe play with dizzy, and pray belt doesn't break.
i don't see why there would be any more strain on the belt as long as components are properly aligned.

 

reverse spinning starter

 

What advantages or disadvantages would this have?
Has it been done b4?

 

camshaft grinding would be the easy part, water pump would have to be moved, as well as the tensioner because the crank pulls on the exhaust cam. everything on the front of the engine would have to be mirror'd for the crank to pull on the intake cam. and i don't see any advantages in doing this.

if your talking about engine effeciency in the way it opperates, it's already very well designed for being an L4 engine. in theroy though the flat four's should be even more effecient. stress loads on both are always opposing each other. the only difference is you have an added stress load from the camshafts and valve train. the flat fours have an even distribution of the stress load.

 

If you waste your time thinking about stupid stuff your never going to accomplish anything.
