I'm thinking about swapping to the h22a motor. My question is can I do a straight swap or Will I have to by different mounts and can I use my f22 transmission???

 

This has been done to exhaustion. Look online and you'll find the answer. You can use the f22 trans if it still shifts smooth. I would at least pull the trans anyway, buy a lsd, and pay a shop to put the lsd in. Either way, its another grand to budget for, the difference is whether you want the engine to spin at 3200 rpm or 2500 rpm on the freeway.
