I want to do an engine swap. Either between an H22 or a GSR engine.Which engine has more power and would fit and line up with my 91' 4 dr Accord better weight wise?

Search the threads...there are several on this or similar topics...but

Get the H22, the B18 (since you already have a F22) would be a drop in displacement and it is a harder swap...the H22 is like a cake walk as far as swaps go and it is a much better starting point for power upgrades. check this out

yes i know it's for a 5thgen but it tells you everything you need to know for a 4thgen as well and it's even easier plus you can use your existing tranny and other parts if your swap doesn't come with these...you don't even have to buy motor mounts they're all the same.

This link even tells you what year model engine swaps the easiest into your year model and etc.

Good Luck!

Note: yes the H22 is heavier than the B18 but that is more than made up for buy the fact that it is a better engine to swap into your car.
