2uz fj40

[Red Dragon]

Picked up a new project, the FJ 40 from Hardline Crawlers forum:
FJ40 Land Cruiser (Tons/Linked/v8 etc) PLUS LOTS OF PARTS
Its a 73 frame with a aluminum tub, and cut front fenders. CUCV dana 60 front with 4.56 gears, Detroit locker, rear is a 14 Bolt 4.56 gears, gov't locker. Rear has been four linked with some stock TJ springs, Rusty's offroad joints and have the brackets and joints to link the front. Chevy TBI V-8 engine swap, that is for sale.
This will be a slow build, but the plans are to remove the Chevy motor, install the 2UZ from the wrecked Tundra, Inchworm prerunner adapter for the 2wd trans to mini truck T-case, and some properly sized tires to get it road worthy. Sliders, tube fenders, roll cage, and then four link the front with some ORI struts to get it trail worthy.

Wrecked Tundra with donor 2UZ and auto trans.

Inchworm adapter:

Still doing research so any items I should adress or tricks to make a better out come post up.

Nice!! Looks like you're going to be having some fun.. Always loved the shorty 40s but in this part of the world "Car cancer" got most of them and what's left are a tad overpriced "Cruiser Tax" if you will.

Tip number one.. SC400 rear sump on the 2UZ will solve a few headaches with clearing the front diff

If you want a manual box use the R150 from a V6 4runner with the same kit to put it on the back of a 1UZ with an inchworm or trailgear kit to use the appropriate transfer depending on the diff configuration, was "offset, offset" on the 'Cruisers but given that it's had Danas fitted (and looking at the pics in the link halfway thru the post) I'd be inclined to run manual with dual gear driven Hilux transfers.

Now from memory the original tyre size on the FJ40 was 7.50x16 so given the 4.56 gearing a tyre size such as 275/75x16 should be spot on for highway driving giving you around 2700rpm at 60mph

Like the auto and since all I need is the PreRunner adapter to attach the T-case no need to try to source and attach something else. Also have to see how long the drivetrain will be before deciding on dual or single case for the rear driveshaft angles.
Will look into rear sump, also read about swapping the oil filter housing so that it points forward instead of down. Thanks for the tips.

Have you considered a 4x4 2uz sump. We see them in landcruisers. Thats what we prefer to use in our similar conversions. We also have a FJ40 in at the moment. Also with Auto but with an early 1uz. Cheers

 

[Red Dragon]

Not sure what would work best at the moment. Was hoping the front Dana 60 was moved far enough forward that oil pan clearence was not an issue.

 

[Red Dragon]

Mounted the 40" Trepadors on the H2 wheels and did some clearance checks, all looks good so far. Unable to flex it to much with just a floor jack, but I know its going to be tall.:frown:
Also took one inch out of the 2 inch body lift, next is finish cleaning up the frame in prep for the engine swap.

Drove the tundra into the shop this morning and did a chop shop job on it. Pulled the drivetrain and wiring harness before loading up the rest to sell for scrap.

Got the motor freshened up today with new Asin water pump, thermostat, timing belt with new tensioner, new crank seal, serpentine belt, and valve covers seals.


Swapped in some some 4.7 gears into a mini truck T-case and installed the rear disconnect for front digs.

Then installed the Inchworm Worm Gear prerunner adapter on the trans and ready for the new transfercase.

Cool project. I take it that the Tundra was 2wd.


How many miles were on the 2uz?


Don't get rid of the doner yet. You need the ignition key assembly.

Not sure of the mileage motor swapped in a year before it was wrecked by the previous owner.

Stripped all the electrical, steering colomun, AC, and dash. Even kept the fuel tank.

Polished up the trans some with a soft wire wheel cup and grinder.

Cool build. Hopefully I'll be building something similar pretty soon. Are you planning to wire it yourself?

 

[Red Dragon]

Drop the motor into the frame rails today to get an idea for some motor mounts.


PS pulley is to close to the shock mounts, may swap to some shock hoops.

Plan to use as much of the stock wiring as possible, with a minimum of tie ins.

 

[Red Dragon]

Cut down the stock motor mounts and used some bomb proof mounts in place of the isolators. Bolted the mounts in the drain holes in the 2UZ cast block mounts after making a smooth flat mounting surface. Cut off the shock mounts and cleaned alittle bit more on the frame.

Then removed the Bowtie and added a Sombrero to the grill.

With the help of a few BSLCA members, we got the motor positioned in the frame and began to fit the Tundra frame motor mounts. Plated the frame some and then trimmed the factory Tundra frame mounts to allow for the new motor placement. Tacked everything up and pulled the engine out to do some full welds. Still have lots of grinding, because I am no where near a good welder, before some paint and final install.





Finished with the welding, grinding, and started with painting after cleaning up a few other spots on the frame.




Started graphing in the Tundra tilt steering column, which well help with all the electrical switches and some leg room.


Also started on a shifter handle to move the rear disconnect next to the twin sticks, just need to add a linkage.

 

[Red Dragon]

So, my buddy was able to help me with wiring harness so we trimmed it down to what we needed using the EWD from TIS. Found out that the FJ 40 and Tundra headlight plugs are the same, also the Tundra brake light switch will screw into the 40's mount. Just need to figure out the FJ 40's wiper motor wiring to tie in the Tundra harness.



Put the steering column back in and stuffed the instrument cluster in the dash that still needs some work for a more finish look. Also worked on the air filter and intake, then prepared the battery box to mount where the blower fan use to mount.

 

[Red Dragon]

Can I tie the valve cover vents line together at the throttle body? Originally the passenger side valve went to the air intake tube and driver side goes to the throttle body, but now the air tube only has three ports and I need four.
