not an H22 but ive done a f22b (the JDM DOHC H23 equivelent that came in non vtec JDM ludes) swap in a civic (well the mechanical part, wiring was done by someone else) and pretty much as straight forward as a b-series but you do have to cut the passenger side frame rail mount off and cut 2 big ass holes in your floorpan. if you can get over that than your good. i didnt have to worry cause itr wasnt my car (still came out good)

die grinders and air chisel are your best friend for these projects though
