You said you needed it on a budget, what exactly is your budget. I was going H-series in my 96 teg for a while, but found out it really can't be done cheaply, your lookin at LEAST 2-2500 assuming you do all the work yourself.
But to answer your other question;
You'll need mounts (500ish), customs axles, a modified shift linkage, of course the motor/tranny, the ECU for the H22, and I'm sure various other nick-nacks to make it all work.
