I had a zc in it but it blew and I've decided to do an H22a I've heard it's a pretty complicating swap in the 4th gen compared to the 5th gen can I get some info on all that's needed to do to make it fit different axels wiring harness,mounts,computer,fuel pump......everything info appreciated

also I know it's way heavy but I'm willing to do the suspension work to correct the understeer info on that would be great also thanks!!!!!!
