F22 to H23 or H22 Swap Possible?? - Honda Prelude Forum

I'm no prelude expert.

I just wrecked my recently purchased '92 S with the f22a engine. Mechanically, the car is fine...the body and radiator support are junk now. It is possible to swap my good engine (f22) into an Si or 4WS Si with a h23 engine?? What problems would I expect to encounter(?), given they are both 5spds.

Any help is greatly appreciated. I just want back on the road.

Why would you want to swap a f22 into an si? You're replacing a stronger motor with a weaker one. It'll work with no problems but I don't understand why you'd want to.

Yes, I would prefer the Si engine, but I'm living on med student loans, which don't budget for cars or car parts. I need to use what I have. If I found a 92-96 VTEC 5spd with a bad engine, would the f22 bolt on with no problems as well?

You would want to use the ECU from the 92 s model, but other than that everything should work fine.

I know this thread is old and i appologise but i am about to make a paper weight of my F22a1 and i am craving some h22 goodness but not sure about direct swap if it will fit or if i will need anything major other than engine tranny and ecu the F22a1 was/is SOHC Non-Vtec and H22 is DOHC VTEC is there going to be wiring issues or cv joint issues i should prepare for? i searched the forums the best i could sorry if its already poasted.
