    R150F to transfer case question

    Guys sorry for the newb question.

    I have a 94 runner that I just swapped a R150F in. The transmission is 23 spline output. I found a gear tcase locally for cheap but it's 21 spline. I really don't want a 21 spline tcase.

    Can I swap the input shaft and convert into a 23 spline? How much stronger is it?


    I really want to run a AA adapter and run a Atlas but I haven't decided to spend that much money on a Tcase just yet.
    Thanks

    Yes
    but marlin is outta stock so trail gear.
    Think about long range cost of doing a doubler ect. Vs atlas now...

    to coin a phrase oft used

      R150 will have a chain drive case, you'll need an adapter and a gear drive 23 spline input. No advantage at all if you aren't doing duals or a 4.7 gear at the same time. If you do a 4.7 gear, you just order it with a 23 input.

        Guys,
        I do plan on the 4.7 reduction which is the whole reason for the tcase swap. I'm just not sure I'll be happy with a stock gear case 4.7 swapped. I'm running 1 tons with 40's and will do an engine swap later down the road.

        I personally believe my tcase will be a weak link if I go with a stock 4.7 swapped case. Some people say they are super tough and some say if you're running larger axles and tall tires it'll still break.

          You should go up top and fill in the ENTIRE plan so we can give good advice..
          sight unseen I think, 4 gear atlas tighter package and marginally more $$$

          first pick eng. Then build rearward.

              Id just go Atlas now. buy once cry once. I did the same thing just wished I would have went with a 4 speed instead of an Atlas 2.
              What is your current engine a 3.0? Planning on going to a 3.4?

                Current engine is the 3.0. Planning for a 3.4 later. The build is taking all my extra cash right now. Engine swap isn't in the budget right now.

                  Understandable.

                  On tons and 40s Id still go with an atlas.

                      Swap back to A340 and go atlas 2 speed. 4 speed if you keep the R150F.

                        How much of a trail rig will it be? An atlas gets into the floor for the passenger seat.

                        that’s where I’m at in turning my 4runner into a

                          Axle gearing makes a big difference. For some reason there was a big trend ~10 years ago where everyone thought it was cool to put 1 tons and 40-44s on their toyota, but leave the 4.10s in the axles. This puts crazy stress on the tcases.

                          On the other end of the spectrum, I know a local guy who put 1 tons with 7.17s in his toyota and has ran 42-49s for 10 years with bone stock tcases and no issues.

                          I ve ran them through a lot of shit in my old tubed samurai on 37 stickies and 4.10s (broke 2 rear out puts being dumb) and my heavy 4runner with 35-42s (twisted 1 front out put with 4.10s and 39 stickies, being dumb)

                          Toyota cases are strong, and will hold up to a lot. But they have a point where they don't make sense. As tcases get harder to find, and more and more people are building rigs where you need an adapter to run them, plus 2 donor cases, atlas looks better and better. I have a hard time running them behind anything bigger than a 4cyl.

                          I wouldn't bother with a single 4.7 honestly.

                            I remember that thread. I learned a lot about matching the ratios.

                            personally I think 37s and under should be toy cases. 40s can be adult driven. More than that and you don’t need Toyota drivetrain.

                              Tire size doesn't matter as long as you have decent axle gears.
