I did a search and didn't have much luck in regards to finding the info I needed. I'll be ordering my H22a soon and I am just trying to confirm what exact parts I will need to complete this swap correctly into my 5th gen sedan.

Whoever knows or has done this swap please help me out so I can round up these parts in the mean time so I have them when it comes time to yank the motor out.

IF you go with a good company to get your motor from, it should come with everything you need (Engine, ECU, exhaust manifold and downpipe, axles, shift linkage). The items I went and sprung for were maintenance parts like new timing belt, water pump, cap & rotor, spark plugs, spark plug wires, all kinds of gaskets just to give you an idea. I also purchased an ACT clutch kit, AEM cai (for 'lude), and some othe little goodies.
