Tundra V8 and auto in a Jeep Grand wagoneer

[clembs]

Hey everybody, I just finished my '70 FJ40 resto and have the green light to start my next project. I picked up a complete '87 Grand Wagoneer (FSJ) for $600 and plan to make it a nice DD. My issue is the truck has 109k on it and the 360ci is a heavy engine and only produced 140hp stock so they got 8-10mpg when new. My family has a couple early Tundra SR5s and I love the 4.7v8. I was wondering if anyone has transplanted the Toyo 4.7 and auto into a non toyo for a reliable DD conversion? I am keen on also using the T-case but haven't looked into it.
My overall question is what parts/ ecu's, gauge cluster parts/ shifters? are needed to make a Jeep grand wagon a full 4.7 Toyo drivetrain?
I am not worried about engine/ tranny mounts and frame mods at this time, just want to know if it's possible
Thanks,
Brent

Try over in hardcore corner or general tech.

The 2UZ is a giant steel lump of a motor. The ratio of horsepower to weight is terrible compared to a LS swap. And there are a gazillion options for LS swaps, standalone harnesses, mounts, etc. for Jeeps.

Its doable, but novack makes bolt in motor mounts for a Jeep SJ that take a LS motor. A LS wiring harness can be made into a stand alone unit by 150tunes for $400. a '87 SJ will be driver side front diff, so use the 4l60e and a NP231C or np241 to save on adapters. A new radiator with GM inputs instead of the old AMC inputs, a fuel pump from a suburban can be used in teh SJ stock tank. Then, driveshaft adjustments and a new exhaust. Done.

So LS is the way to go i'm hearing. Bama would you be so helpful if you knew i went to Clemson? Just kidding all the Bama people I know are fantastic. What do you mean by "passenger drop"? does that mean I'll have to lose the center front seat for a floor shifter/t-case shifter, or something like that?

We're 2-2 with clemson the last four years and won 5 out of the 7 national championships we've played for over the past 11 years. We're good. Passenger drop as in the location of the differential on the front axle. Jeep changed from a passenger side diff to a driver's side diff in the early 80s. I corrected my fist post. It is easier to use a GM transfer case with the GM transmission to save from having to buy an expensive adapter to mount the jeep transfer case. Using an early '90s GM case like a NP231C with the 6 planetary gears and 1.5" chain will give you a stout case, allow you to bolt up to a 4l60e and then use the back have of a jeep NP231J to be able to plug your speedo gear into it and be able to install slip yoke eliminator kit. The 727 auto and np208 trans/tcase combo behind the 360 are stout, but I'd just go all GM to have a 5th gear overdrive.

Thanks Bama, I am going to get it up on the lift in the next month and see how the overall truck looks with rust and unseen cost/ time. I am temped to just get it running and cleaned up then do the swap down the road but if I need to start putting money and time into the stock truck i'll go the swap idea bc I'll already be removing so much (tank, suspension, cross members, etc. And haven't tried turning the engine over yet by hand so it may be decided for me

I was into Jeeps before Toyotas - CJs and FSJs. I built a GW (lifted, cut, integrated sliders, winch... ) Even with a new 360 and all the trick upgrades, it was sloooooow.

So, when it was decision time for the engine in the Scrambler - it got an LS. Everything was off-the-shelf. It was so nice to have a 300+ HP motor that ran cool, idled smoothly and - get this - started. Unique for Jeeps.

Nice-(bofum)

The GW would be worth some coin these days- retro rigs are all rage with hipsters at the moment.

Thanks for the post Manhattan those are both beautiful trucks. what lift did you have on the GW? I am wanting a 2" with 31bfg km2's nothing too big. My wagon is grey with burgundy int and I hope to make it look much like your GW. I am just trying to think of up front cost for the Wagon build. My agreement with my wife is that I build the GW nice enough to show clients (im a Realtor) then I sell my present LR LR3 and put the money back in the bank. Only issue is paying for everything before having the liquid funds and an LS swap may add some time to the build due to cost

love both of them. (even if your boomerang shacles on the CJ8 are upside down and backwards)

 

[clembs]

Also when you are talking about LS engines, are you including the 5.3L also or just 5.7s? I have a fear of the 5.3 bc of the trouble my bro in law had with his '05 tahoe, and a friend's Burbon both needing engine replacements. What LS would you rec to use

That was done on purpose. The theory (after building lots of CJs) was to fix the stabby shackle thing - they point down and forward and get stuck on rocks, ledges, etc. on approach. Flipping them was to make them less stabby... theoretically. That theory was never tested. Right after finishing the Jeep, some dude had to have it - kept texting pics of checks 'till one was big enough.

after also building a lot of CJs and YJs, that theory doesn't work. The boomerang was designed to keep the spring from inverting when flexing. Those rubicon express springs were notorious for that. The point should points should go towards the center, at top in the front, and bottom on the rear.
