will my aftermarket headers fit ,pullys,intake?

If oyu are talking about internals then you can use the entire short block from the F22A sohc motor.However this is not a straight forward build. There is a considerable amount of machine work necassary or the H22A head to mate properly.There is an article about this on www.honda-tech.com that was posted a few years ago so search the archives.Now if oyu are talking about accesories such as the a/c or alternator Im not entirely sure. Since I dont know the AMP rating of the alternator and bolt configuration of the A/C pump.

your aftermarket headers WILL fit.... i'm not sure about your pulleys b/c the diameter of everything coming out of the engine might be different than the diameter of the pulleys. you'll just have to guess and check on those..... and again.... the same with the intake.... that all depends on what type etc..... if you have further Q's feel free to contact me @ racrboy_71@yahoo.com. I have owned 4 hondas and swapped a B-17 MUGEN SPOON into my current Si. I will help you as much as i can.

My guess is that your staying OBD2, if you can convert it to OBD1. Your aftermarket headers WILL NOT fit because the exhaust port holes on the f22b1 or f22b2 are like this 0 00 0And the exhaust ports on the h22a are like this 0 0 0 0So they wont fit. The intake can be fabricated to fit but I dont recommend it because the pipe diameter is smaller on a f22 engine. Meaning that the h22 throttle body will be bigger then the diameter for the intake for the f22. Get a short ram for a h22a and shorten it slightly to fit, or there are other options. The pulleys will fit.
