yes i know alot of post like this but this one is kinda specific.. if i was swaping from N H23 to an h22a 200 hp motor what else will i need to purches to make the swap to work for example will the water pumps swap over will the starter swap over power steering pump ext.. anything else i would have to buy ? thanks in advance to anyone who has done this

 

I haven't done it personally, but I have assisted a few people. Assuming you get a long block, tranny and an ECU... Since the engine will be off the car, you might think about replacing:

The clutch
All Belts
Oil pan gasket,
Valve cover gasket and grommets
Timing belt, and cover gasket
Engine Mounts
Alternator
Dizzy (Distributor)
Plugs and wires
Intake Manifold Gasket
1/2 shafts (CVs, axles whatever)
Front Wheel Bearings.

Make sure you get all the necessary harnesses. It took 3 of us 1 weekend to get the a blown engine out of the car, and 2 weekends to get the new one in replacing most of that list.

 

does anyone have a write up of a f22a4 (honda prelude S) to a JDM h22a motor swap?

 

yes
ive attached a helpful text file, it covers everything u need to know
good luck
