H22 VS. F20b which one to choose?????

S-spec · Dec 16, 2007

PS - it was mentioned before, but make sure the F20B motor was from a manual car. The Autos came with 180 hp, the manuals with 200. If it doesn't have a tranny, or at least a flywheel, chances are it was from an auto. Even if it does have a flywheel...its sketch without the tranny. No reason to split it.

Yep and be careful most of them on sale or for dirt cheap are F20B Auto's.

if u buy a f20b just look at the throttle cable ring, if it has a provision or extra slot it is for an auto, only supposed to have one slot for one cable, this is a manual transmission engine.

Do you know what's the actual differences between the auto and manual f20b? The internals should be identical, I always guessed the difference was mainly in the ecu tune to make the auto more practical. Could be completely wrong though.
