Builds 94 Toyota Pickup on 94 80 series chassis (6 Viewers)

[HiCruiser LandLux]

The main reason I strayed away from duals was I had heard lots of horror stories about big power and big tires killing them. I'm pretty sane, but I've put the boot to the floor out of frustration before, and 250hp and tq seemed a bit much for duals, especially when you think about how much torque you're putting on input shaft #2.

I'm just telling you my personal experience. I thought I could use the higher trans gears like you mentioned. I "read somewhere" that's not a great idea. Something about the higher gears not being up to the task strength wise. IDK if it's true but ,it was a pain in the ass doing it anyway and the gears were screaming when I did. It got old fast.

From my logic, not using anything other then beer math, running 4th gear through the lowrange set should be less torque applied to it, therefore less stress on it. I can definitely see how gear noise gets old, didn't think about that. If this ends up being a massive PITA I have the option of either going to dual 2.28's or keep my 4.7 with a 2.28

Another reason that I stayed away from duals and chose the landcruiser chassis in the first place was because I plan on towing with this rig. The Celica pictured above on a light aluminum trailer is gonna be about 4000lbs to 4500lbs. In my head that many adapters and coupler in a line with that much weight stresses me out, especially when you consider the fact they're cases from a late 70's mini truck with 90hp and 29" tires. If towing is too much for the single case to handle I will be looking into either an Atlas 2 or 4 speed transfer case

 

[aztoyman]

Oh I get your logic. You have more power than I do, more weight and towing. I get it. You have a different rig and different priorities than I do.

I thought I made the right choice with a single case and 4.7's and I experienced things I didn't think about. Just throwing it out there so you lose sleep ha ha.

It's the strength of the trans gears being weaker in 4th and 5th I was talking about. Also just what I've been "told". IDK if it's fact.

I'm also poor now so I gotta run what I have and hopefully make it last. See, different priorities. I'm enjoying your build, sorry to derail it.

No dont feel bad at all. I get too much sleep anyways lol. I appreciate the hell outta you looking at it from another angle then I would. The 4.7 is definitely gonna be a compromise, but I think/hope/pray its the right list of pros and cons for me

 

[LowDown]

Bitchin' build. I really dig it. Hoping the 1UZ doesn't grenade the tcase output shaft...fingers crossed.

 

[aztoyman]

I think Marlin sells a high strength output shaft. The good thing is the op is already nervous about it failing. Hopefully he drives with that in mind but, you know how it goes when you have power. I know because I used to be young and blew $hit up. But now I'm old and wiser......kinda.

I wish him luck, I like this build and will be following along.

 

[Broski]

I'm really liking this build also !! I do think he should go with a 80 TC and a black box. Keep it all Toyota

Yall bastards just cost me $600 lolol. Marlin doesn't make a high strength output, but TrailGear Longfield does. Should be the last component for beefing up the case unless y'all can think of anything else lol

I couldn't figure out a cost effective way to bolt a LandCruiser case to a manual r150f. I know they came that way in Australia in the stick cruisers, but short of importing something im SOL there

 

[aztoyman]

I'm helping you spend YOUR money and maybe you'll chicken out, go Atlas and I'll buy it off you.

I was thinking a North West fab Black box would bolt to the r150f but I could be mistaken.
But I know you on a set path and don’t want to spend any more of your money we’re good at that on Mud.

Ultimately I would have stay with the Cruiser Trans & TF Case with the Black box in between. That would’ve affectively given you a 4 speed transfer case.
And a combo that would hold up to V8 power.
And I prefer an automatic.
That’s for another thread and another build

The black box is actually a sick little unit! I don't see any options to go to an r150f but I'm they could make it happen. Sadly I'm pretty stuck on making my gear drive case work at this point lol, sorry @aztoyman

Another thing is personally I just can't stand automatic 4x4's from a enjoyment side of things. They're definitely better though, I wont lie, a full 100 series powertrain nearly ended up in this rig. But dammit the truck started out with 3 pedals, its keeping them lol

It'll work until it doesn't! In double low, behind a stock LS 5.3L, I grenaded the stock output shaft in my old Toyota mini-truck doubler as I was coming off idle.
Stock 5.3 - W56 - 2.28 (23 spline) 4.7 (stock output shaft). 39" red labels, 5000 lb rig. I'm not saying you're doomed but definitely go with the upgraded output shaft and keep in the back of your mind that you're likely to eventually out grow the Toyota t-case and end up with another set up. I went ORD Magnum-205 and have beaten the hell out of my FJ over the last 5 years.

That actually makes me much less nervous then I had been. 1UZ is either equal or less power then a 5.3, not running dual cases so thats at least 2.28 times less torque on it. I just ordered the upgraded shaft too as it was on sale lucky for me. I've spent my whole lunch break today looking for examples of the longfield shaft failing and haven't seen anything yet luckily. Also y'all have definitely superglued the idea of going to an Atlas case or equivalent long term.

Guess what showed up today. You guys suck lol. Thanks for the input on the output, gonna be assembling the case at work tomorrow. Excited to see how they turnout.

Get it done!!

When I ran double cases (trailgear 4.7 geared case w/stock chain 3rd gen 4runner case) with a stock 3.4L and 33" tires I had nothing but issues from day one after it was installed. Trail gear case would pop out of gear going down hill. After that was "fixed" and I was able to put some trips some on said I found case was leaking so I pulled it and found they didn't cover all the case edges with sealer, which turned out in my favor, during said reseal I found a lot of the metal paste formed during metal parts breaking down, the trailgear case gears had lots of chipping on the teeth. After pulling and reinstalling the tcases around 10 times over the yr I owed it I pulled said and sent it back for the 2nd time. On trailgears side they did replace the case with a new unit but I sold off for 1/2 cost and went with a 4 speed atlas. I also later found I had also stretched the stock 4runner tcase's chain during the time I ran the doubles

 

[HiCruiser LandLux]

Well finally got stuck into the t case. Started by pulling it off the trucks w56, drained and cleaned the exterior

Pulled the case apart, kept the components grouped, washed the bits of the case that will be reused, sandblasted, rewashed and painted them, as well as the Advance Adapters reduction housing

Pretty excited and hopeful about the strength of the Longfield output, and Marlin 4.7 gears. Got the new trail gear shift rails for the top shift conversion in as well. All new bearings of course

Fought some of the bastard retaining clips for a good while, didn't have the proper type of snap ring pliers. Of course made sure everything was smoothly operating as it went together.

Got the FROR twinsticks on as soon as I had it finished, super satisfied with how they shift. The triple drilled flanges are also Handy as I'll be using the big LandCruiser sized Driveline flanges. If y'all are right and I grenade this thing, it'll at least have had the best chance and it'll look pretty decent lol

Had to test fit the transfer case mount when I got home lol. Fits good, even around the speed sensor, only issue is having to either remove the rear of the t case every time i pull the powertrain or having to pull the case off the transmission. Small issues that shouldn't matter much too much though.

 

[LowDown]

Nice, no time wasted!

 

[aztoyman]

I originally went with that mount and I worried that any twist from the engine would load the case and cause the gaskets to leak at minimum or possibly crack the case. That is going to hold your T-case a lot more solid than your engine mounts (If they're stock) The original T-case mounts on the bottom will at least allow the entire case to flex over.

I have stock OEM 3.4 mounts and I had a lot of movement. My shifters moved a lot so I attached a cable from a shock hoop to the engine lifting bracket toward the top of the driver side head to limit that movement. It worked great. I got the idea from an old Pirate post. They were using a piece of chain though.

There's a few posts out there about that FROR mount where somebody says it breaks cases but no proof and plenty of people running them that say no problems. It caused ME concern so I went back to the bomb proof mounts in the stock location. Since you don't have that option, maybe think about something to limit your engine torquing over. Or maybe I'm worrying about a non issue. It saved me from tearing out engine mounts at least.

The case looks awesome! I love nice clean parts. This is going to be Baddass.

 

[HiCruiser LandLux]

Alrighty. Finally got some time to work on the ol rig again. The ever divisive transfer case has found its home even

Even if it does turn into goo it'll look nice as it goes. This is the Advance Adapters plate, it fit okay, little annoying with fastener placement and the fact you need 4 different lengths of fasteners. Also jad to trim the 4wd shift fork down to fit.

Mocked up the FROR cross memeber and uhh should have measured. Bought the mini truck fully welded one trying to be lazy and save time, landcruiser chassis is narrower, gonna have to cut it done a bit

Maybe ill just mount it to the top of the frame rails lolol. In other news finished the motor mounts, didnt catch pictures of sfter i shaved the OEM mounts. Probably gonna do some 1/8" steel braces on the tube mounts.

Not winning the beauty contest but it'll do nicely I think
