Thanks Mike-
That's a good suggestion about the 2WD. I would like to find some gear-ratio numbers for the 4wd, 2WD and Supra transmissions. We're running 5.29's with 35" tires and I would prefer to keep the spread tight and lose a deep 1st, etc.
Regarding the bellhousing:
I wonder if the pilot bearing/input shaft are at least the same dimensions between the two transmissions. I guess the next thing to look into would be the length of each bellhousing from the block mounting surface to the transmission mounting surface. I could use a bell-housing from either R151F/R150F (since it's not likely that either could be used to determine the starter mounting location anyway), right?
I would definately want to stay with the chain-driven case because of the driver's-side front differential. Do the V6 and 4cyl Tacoma trucks use different transfer-cases?
I'm very interested to hear what Marlin has to say about all of this. Especially the Tacoma/Supra hybrid trans. That would have much wider appeal than anything I'm working on with this 3RZ truck.
Hey why don't we both edit our previous posts to cut this thread down to some good technical information?
