ok here is the deal im gettin bored of my massive b18 swap in my crx for those of you who have been here awhile you know what im talkin bout. never thought id get bored with roughly 300 hp b18a. but i am so im thinkin bout puttin in a h23 vtec with a jackson supercharger with 25 psi.... what i want to know is how do i put my h series into a 91 crx si that previously housed a obd-0 b18a1?  

buy the full swap from h motors, send your harnesses, ef and h23 vtec, to rywire, buy mounts h mounts into ef, cut a hole in your hood depending on your front end (if its sir front and you use innovative mounts you wont have to if, if you use hasport you will, but remember h series has a low hanging exhaust manifold and oil pan).there is a little modification to the tranny mount. You will also need axles and shift linkage. There is some more but that's just the basics.
