Other tid bits my Dad and I have done is put in a new short block, fresh head, oil pump, steel timming guide, torque cam, etc. As I've said before, the cam is the best bang for the buck on these 22R motors. We also rebuilt a w56 transmission from a '87 4runner, which I might replace with a R150f and VF1A t-case.
While my Dad had another engine on the stand he worked out the issues with mounting a 7mge 90 amp alternator on the 22r. We took it off a MKIII supra automatic. The lower mount had to be filed down to fit into the 22R bracket. Then the pully off the old alternator had to be drilled out to mount on the new 90amp unit. The bracket for the belt adjustment also had to be extended, I used a ground down piece of the bracket as an extender. It's a pain to get down in to place and I had to unbolt the power steering pump. Also the cables are hard to reach being clocked towards the block. However, it keeps up great with my stereo.
Also under the hood is a brake booster and master cylinder off a Tundra. It works great and the only issue is that the reservoir of the clutch master is pushed over just a bit. I also upgraded to V6 callipers up front.
