R151+RF1A questions
Hi all, new to the forum.
I’ve picked up a somewhat cobbled-together R151 paired to an RF1A. All is well except the transfer was converted to top-shift when the input shaft was swapped. The current setup is crude, at best, and requires a 2” bodylift to fit. Would it be possible to swap in extended factory shift joints without tearing the case apart? It’s out of the car at the moment so I’d like to get it sorted!

Welcome, you should introduce yourself in intro section.
To completely answer your question I can't say. But for my crawler box was was forwardshift when I got it. I trimmed shaft to be a topshift without disassembling box. Might take another set of hands.

Hey thanks for the reply. I know that most people seem to prefer a a top-shift box, but I want to make this fit as factory as possible. This will be replacing a G52.I’ll make my way to the intro section.

Talk with Rory at RADesigns. He set me up with my triple stick setup. All you would need is a "forward mount twin stick" setup:

Thanks for the advice, but yikes that’s a lot of money! I’ve got access to factory selector rods, and I can extend them to account for the adapter plate, but my question is: do I have to crack the case open to swap them?

Found you a tutorial with pictures. Good old 4x4wire.com. It's a tutorial on how to convert an RF1A from forward-shift to top-shift. If I understand correctly you are trying to do the opposite, still it's got everything you need. http://www.4x4wire.com/toyota/tech/topshifter/

Fantastic. I saw a similar thread on another forum but it skipped past the shaft removal. Fair enough, I’ll have to crack it apart. Now if I can just figure out how to clear the intercooler I can peg stock body height.

You've got my curiosity going now. You said something about an intercooler. I can't immediately think of any ’86 - ’95 Toyota pickups/4runners that came with an intercooler. Care to expand on that?
I'm interested because finding a spot for an intercooler has always been a problem for these vehicles and because I have been thinking about a VW diesel swap for my first generation 4runner. I have recently learned that the 2.o BHW engine in the 2004 - 2005 Passat will put out 173 hp and 305 tq with the only modification being a tune for the ECU.

Not in those years, but around 2000 they added an intercooler on some of the land cruisers with the 1KZ. These made 145hp and 253lbs/ft - I should hopefully be able to safely dial it past that. I’ve just ripped out all the EFI and got a mitsu 4m40 pump running on it yesterday. Still need to sort out the transfer linkages though.For reference:
