Need driver side drop transfer case solution for R-series transmission
Been searching around and can't seem to find an answer. Is there any way to mate a driver side drop chain drive transfer case from a '99 Tacoma to an R151F ('86/'87)? The R151F has the 7-bolt cover, and '99 Tacoma uses the 5-bolt cover. I can't seem to find an adapter from Novak, AA, Marlin, Inchworm, etc... unless I'm just inept. I see adapters to put gear driven cases on newer Tacos, but nothing to put a newer chain drive cases on an older truck transmission (I know, who would want to do that?! Please don't flame.). There is inchworm's lefty adapter, but at $800...ouch! Or am I misunderstanding some of the adapter options and what I'm looking for is right under my nose?
Along the same lines, would a '99 driver side drop t-case mate up to an older '80s era R150F? Do they share the same output? Or would a newer Taco R150F mate up to the 22R-style engine with proper bellhousing?
I'm putting this setup behind a VW 1.9TD with the Acme adapter (which makes it a 22-R style engine). This is going into a Jeep XJ, which is why it needs to be driver side drop. I basically see two options (I think):
1. R151F with '99 Tacoma t-case
2. Older R150F with R151F bellhousing and '99 Tacoma t-case
3. Newer R150F with R151F bellhousing and '99 Tacoma t-case
I'm sure there's probably a dual-case setup that could work, throwing a driver side drop D300 on the back of a gear-driven passenger drop t-case, but I'm not going for a dual setup at this point. I also don't want to swap axles on the Jeep to make it passenger drop.
So, any thoughts?
I'd really like to hear options using the R151F most of all, as I already have the R151F and '99 Tacoma t-case. I could sell them, of course, and go with another option if a truly better one exists, but if there's any way to work with what I already have, I'd love to hear it.
Is this another option? http://www.inchwormgear.com/store/pr...products_id=72
Still, I'd like to find something that is slightly less expensive.
Thanks.

Why not just use the Taco R150? Why are you so set on using the R151? Because of the steep first gear? You do know they R150 and R151 share the same strength, right? No one makes an adapter from a gear driven R series trans to a chain driven case, you are going backwards. Your easiest and cheapest solution is to look for a 95.5 and newer R150f.

But I still need the bellhousing from R151F, right? R150 all mated to V6. I have no problem using a 95+ Taco R150F. I just want to be sure the R151F bellhousing will mate up to it so I can put it behind my 22R style motor.

I'm digging at an old thread here because I have all the parts listed ^^^ on the bench and I'm attempting the same thing....OK the taco r150f T-case adapter is NOT a direct fit behind the R151...the bolt pattern is the same, however due to the difference in shift mechanism, forks, detent locations for fifth and reverse it can't be done without alot of cutting up and welding of the tacoma t-case adapter....on top of that the bearing sizes for output are different (larger on the 151) ....still not sure if the taco plastic oil funnel will work with the r151 counter shaft....if the taco did not have a syncro reverse mechanism this would be a relatively straight forward hybrid.....just too much was changed between the non syncro rev r151 and the syncro rev taco r150...
