There's a hole in my block. My car is a 92 h23 and i want to swap in an h22. I have a good idea of what i need. Just wanted to double check. So if anyone knows exactly what i need , please let me know.

Do a search. There is an amazing write up here on exactly what you'll need and how to do it. It's what I used, accompanied with the Helms manual, to do my swap.

If you're transmission is in good condition, then you will only need a h22 longblock. You'll have to modify the wiring harness a little bit.

Make sure you get the ecu and the proper exhaust manifold (stock or aftermarket).
