I would stay away from the heavier 5mge and go with something more modern. If you have access to the 3rz with a engine harness and manual trans ecu, I would go with that setup. You can use your stock radiator, 3rz belhousing and clutch, and a W 56 trans. You have to trade out the oil pain, pick up tube and dipstick from a 3rz equipped T100, cut the motor mounts off of the frame and modify them to be welded back on. Oh, and with this oil pan configuration, it's a great idea to have some lift on the front end or the axle moved forward to clear the pan. Remember, there always other obsticles to overcome when building this that aren't covered on this forum, so don't think you can do it fast - especially your first one.
