well it may take a little longer. you will probably want to put in a new clutch while the engine is out of the car and go ahead and check and make sure no seals or anything are needed. Any H22A clutch SHOULD fit. I will double check. I would go with an exedy clutch (stage 1 if this car is going to be your dd). I have used them with good results.

as for modifications to the F20B, I would go with an Accord Euro R intake manifold and a tuned P73 ecu (ITR). The stock IM is like the stock IM on the USDM H22A. It has 2 runners. The Euro R IM has shorter single runners and is good for about 6 extra WHP. It also sounds a lot better too. Get a good Header also. Other than that, you should be good to go. Keep it simple and you will have a fast, strong, and reliable engine.
