ok i know if you swap a F20C into lets say a CRX you will have 1 drive and 6 reverses unless you do a tube frame and RWD, so my question is far out there but none the less.... can you make the F20C spin the oposite way it does now? machined parts an all

 

sure, with whole new engine management.
But that's just one of your problems, the s2k tranny won't fit any FWD.....

 

well it was a long shot....

im getting a old CRx and im going to dump a japspec prelude type s engine in it, that is unless i do a tube frame CRX and use the F20C RWD setup

 

Hmm.... I donno that it's going to fit....
I mean a B20 is already a very tight squeeze.

 

F20C really isn't any bigger than the B20, although it _might_ be a touch taller - hey, I always wanted a CRX with a pro-stock hood scoop :-)

If I was going to put an F20C in a FWD Honda, I'd look at snagging a tranny from the RSX-S since the K20C rotates in the same direction. Of course, then, why not just pick up a K20C. Probably cheaper and no custom bellhousing needed.

You can't make the engine turn the wrong way, but you can run a transmission backwards (with some major glitching). You would have to turn the engine and transmission assembly 180 degrees from where it usually is in the CRX (so the engine is on the passenger side and the trans is on the driver's side), then you would need a custom bell housing and custom mounts, etc. It would drive, but for whatever reason, I hear honda transmissions grind a lot when run backwards. I can't really explain why, since the syncros look symetrical enough... but I've been told it grinds and breaks pretty quickly.

You can indeed make an engine run in the opposite direction. Some of the key changes:

1. Cam profiles - on most modern profiles, the accel/decel ramps are different in shape, so you need to grind completely new cams.

2. Timing belt - The tensioner needs to be relocated.

3. Oil pump/water pump - depending upon the design, they may not pump properly when run in reverse. Go electric or change the drive system. Race cars usually go dry sump oil and electric water pump.

4. Distributor/ignition system - with direct ignition, no biggy provided your indexing sensor is properly located. Distributor may be tougher.

For reference, many Prelude VTEC based touring car engines are reworked to run clockwise. This makes it easier to run Xtrac trannies (Xtrac finally offers a CCW sequential tranny) as well as orient the intake facing forward and exhaust the rear.
