85 4runner build.

85 4runner build--*UPDATED*Dual Transmissions.

I've been working on this thing for about 3 years now off and on.
Started with a plain jane 85 4runner EFI, 300,000 miles on the Odometer.
How I originally bought it:

Changed a few things up, removed some of the ugly trim

First time out to URE with 31" SSR radials, open front and rear. Spun a bearing on the way up dutch john
I let it sit for about a year after that, mostly because I was frustrated with it.
Ended up throwing a recently rebuilt 22re in it, and traded the blown engine to topless toy for a welded third.

Mixed up the leaf packs, ended up with about a 2-3" lift, and moved the axle forward an inch, and got a smoking deal on 34" LTBs from adam greene. Also went to ECGS and bought some sliders, great guys.

And that's how she sits.
For the future i'm going to start getting more serious on it:
63" Chevy springs, Aussie up front, Longfields, Duals, 36-38" Tires, and an Interior Cage.
That should be able to handle URE at least, until I get a tow rig to head out to bigger areas.

Looks good. Have you thought about doing something besides the Chevies in the rear? Maybe some 54" Explorer leaves?

Little update

Got her up on 36" TSL's
Beadlocks to match
Trip to the beach:

During a ride at Uwharrie, my driveshaft decided it doesn't like rocks as much as I do. Aftermath:

Decided to get rid of the cancer on the rear fenders, and since I had a hard time finding information on how to cut them, I'll do a little write-up to save people some time in the future hopefully.

Tools needed:
3"cutoff wheel(Northern tool has a cheapo that worked great for sale 12$ right now)
Masking tape/pencil
Eye protection

Step one, decide how much you want to take off, for me, I just wanted to get rid of the rust, so I measured how thick the thickest rust was, and cut that much all around the fender.
Another option if you wanted a completely round wheel wll would be to use a string with one end tied to a pencil and the other to a lug nut, to give you a circumference that you could cut along.
My rusty fender:

Masked off where I wanted to cut.

Started cutting, I was a bit apprehensive at first, but got through it.
First layer is cut away, exposing the inner fender well.

Then, just start cutting away along the same lines you cut through on the outer sheet metal.
And viola, you have hopefully cut away the rot, and added some uptravel to your rear suspension.

Rinse and repeat for the other side, here's the leftovers.

To seal off the inside from the weather there are plenty of options, the best would be to weld in between the gap a new panel, I'm not going to do that since I don't want to mess with paint, I plan on fiberglassing the inside, simple and easy for me.

good looking 4 runner man! a black soft top would look amazing on that thing.

Dual transmission installed
I posted this on pirate as well, just have to throw in the fuel tank and I'll let everyone know how it turned out on the street.


Total cost:
Adapter: -225$
G52/G54:-200$
Nuts/Bolts/Metal:-30$
455$, not too bad.

This all has taken about 3 nights of working on it with my brother, all that's left is to put in the gas tank.

I chose the g52 because of a couple reasons, mainly that it's cheaper.
Also, I wanted to test the limits of dual transmissions, might as well see if I can bust a g series tranny before i put a rebuilt w56 back there.
And last, it's easy to find a forward shift case with it, so I don't have the transfer case shifter in the back seat.
On to the pictures
G series Transmission with forward shift case

Removed Bellhousing

19.5 Inches added +2inches of adapter

Cutting the input off at 3 someodd inches. Don't hate on the face shield, I hate fucking sparks in my face.

Transmission with adapter and bearing retainer cut down

Removed the Horsecollar Cross-member for clearance, that was a bitch with a sawzall. We also had to remove the gas tank.

Clearance Clarence.

Our ghetto ratchet strap hoist system.

Finally got it fitted up after 30 minutes or so of frustration, word of advice, break out your calipers and measure your Tcase input spline vs your 2nd Tranny's input spline, ours was a bit off, nothing a flapper wheel couldn't fix though.

All fitted up ready for the crossmember

Reused the stock crossmember, going to put another stock crossmember in the stock location and see how it looks with a peice of plate as a skidplate between them, probably going to be too low though.

Here are my shifters, shouldn't be too far back. Going to weld the 2nd transmission shifter a little more forward so I dont have to shift behind me.

Loooong front driveshaft is long, but got to reuse the stock ones, might need to shorten the rear one a little, but I think I'd rather just move the rear axle back a few inches.

So there it is, 3 nights of work and all that's left is to figure out a good spot for the fuel tank...
Gotta thank Csudman, JLtoy, and freeclimber, and everyone else that has contributed to the various posts about dual transmissions.

OK for the NONtoyota guys please help.
I don't get it. Is the first picture what you started with? or..
Is it the finished project less bell housing?
19.5 inches added, take that away and I don't see anything to shift the original trasmission and transfercase.
I don't see the extra shifter for the added transmission?
Is the original trasmissin an auto? Where is the T-case shifter?(Again, for the non toyota guys)
very curious just want to know
thanks

Chip...I think it's like this. There is no pic of the complete set-up outside of the vehicle. The first pic is of the "new" second transmission before install with the old bell still attached.

Original transfer case is removed. Second transmission (with no bell) only has the adapter and bolts to the tail of the original transmission that no longer has a trsnfer case. The second transmission is the only one with a transfer case.

Only one shifter is in the original position and is for the front transmission (no transfer case on this one) and is not shown.

The pic showing two shifters in the new hole are for the second transmission (one on the right and is cut off short) and for the only transfer case (one on the left). They are so close because it is a forward shift case. The transmission being cut off short tricked me at first because it looks like a dual case set-up.

I'm just trying to figure out the advantage of dual transmissions vs dual cases.

i think i now have your old engine.... you spun that bearing good.

cant wait to see more of this truck

Yea that adapter is way more bling than the one that I had.

 

[Xlain]

Sorry I havnt replied in a while, my keyboard broke.

But freeclimber00 on pirate4x4 made it, I don't know if he has any left though.
Came with a nice set of instructions on what to modify on the transmission and such.

It's just the rear transmission in the first pictures, was just showing how much longer it was going to add to the driveline.
3 shifters- two transmissions and one tcase
I should have gotten a better picture with the first trans shifter
