Very cool kit, sad to see the transmission controller is another $1k.

The conventional 60/80 series Cummins conversion went like this-
Cummins to straight up GM adapter $1150
4L80E $2000
Advance adapters splitacase adapter $600
Splitcase $200
drivelines reworked $600
4L80E controller $600+
Sorting out the transmission and t-case shifters (priceless)
Some kind of tachometer signal converter device $120
My rough math says that's $5K+ on top of what you give for an engine.
With these adapter kits you have-
Cummins to Landcruiser adapter $1250
Reworked Landcruiser converter (if you want to go all out) $250
Compushift controller $1100 or less if you actually call and talk to them.
That Looks like $2K less than the alternative just in parts.
How much is the labor saved by not needing to touch the transmission, deal with the transmission and transfer case shift linkage or reworking the tranny crossmember worth to you? These parts cut the scope of the conversion project in 1/2.
FJ62 and FJ80 don't need the Compushift.
93-94 have a seperate transmission controller that may be useable with some input signal modification.

The numbers don't lie, now if I could find someone to do a swap on the east coast i would be golden
Sweet, now if someone made a motor mount kit instead of me having to fab 1

I will have the opportunity to form up some mounts for various engines in 80 series in a few weeks.
I have a 4BD1T & will definitely throw it in my 91 3FE Landcruiser when it dies. Give me the run down on everything I need to make this happen. I need $ amount as well as parts you make to show to the boss and close the deal. Thanks in advance.

Where are you located? A friend of mine owns a 4x4 shop in Ohio and he will do it.

Hey hey!!!
Is that my adapter kit, I just bought???!!! hahaha
Looks great! Very happy with the finished product. Dustin was a champ to deal with.
It was so pretty I had to share! Thanks again!

The FJ80 Isuzu kit is $1250
Have your converter overhauled with the stall speed changed to 1600-1700 RPM $250
Our Isuzu oil filter relocation block kit $40
A remote oil filter kit of your choice such as one for a PH8A filter around $60
If you were interested in purchasing premade mounts these would be around $200
Buy a Toyota wiring manual for your specific year around $40
Electric fan kit with thermostat (I like the slimline Derale) $210
3" exhaust with a chambered muffler works well and should be around $350 turbo to bumper for an 80 series at a decent muffler shop.
Budget $1000 for hoses, fasteners, filters, oil, tubes, clamps, gaskets, seals, spray paint.
If you want to splurge have the exhaust manifold and turbine housing ceramic coated black. This will run around $200 for both and probably won't make any performance difference, but keeps those two parts looking GREAT pretty much indefinitely.
I see about $3600 in parts there to completely finish your install. $1490 for parts we sell.
Thanks!

A nice option to have in the future for my LX. Plus planning to get an 80 in the Philippines and gassers are sometimes half the price of a diesel 80. Isuzu diesels are also considerably cheaper than toy diesels.

This is exactly why its worth doing, the headache and $$$$$ involved in the alternative, traditional "swap" is ridiculous. Makes someone question why they'd do it in the first place.
I look forward to the first 5k miles after the swap, then we'll see what its all about!!!

Oh, so its for the auto's, a bit of rotating mass to smooth out the engine on those motors then.
On my cummins there is just a flexplate and not any extra rotating mass with the auto's. Well, before I swapped to the NZV4500 anyway.
For your H55 kits, do you provide a new flywheel? Im guessing the 4BT cummins is still an 8 bolt crank, is the isuzu 8 bolt as well or how what is used for the flywheel for the H55f trans conversions?
Thanks!

The Isuzu and Cummins adapters do not interchange. The bolt patterns, dowel locations and crank flange depths are different.
Isuzu 4BD1T/2T/6BD1T have 6 bolt M14X1.5 crankshaft bolt patterns. 6BG1T's have M16X1.5 threads.
The H55 kits use the existing Landcruiser bellhousing and the original 10 7/8" FJ60 clutch. They include the aluminum adapter plate, new forged steel flywheel, starter and bolts.
Has anyone researched what inputs the A442F takes from the 1FZFE in the 93-94 model years? It's a standalone tranny computer with a throttle cable to the valve body, so I'm curious if it needs a TPS signal or anything else for shift points. It seems to me this could be made to work without the compushift?
$1490 with the motor mounts? If so, that's a great deal. My motor even has an intercooler. Had the motor over a year and this is whats been holding it off. I need where and how information. Thanks.

So how is the stock gearing going to work with the Isuzu?

I was actually going to ask this guy to help me out. I read his thread beginning to end and did a good job doing so.

The stock 4.10's work perfect with 35's and a 4 cylinder or 37's and a 6.
33's and 4.10's work fine around town, but 70+ isn't great.
3.73's are available and not all that expensive. This would be the way to go to keep 33's. We recently quoted a complete front and rear 80 series switch to 3.73's from a reputable portland gear shop. The parts and labor total with front axle rebuild was around $1700 iirc.
The Isuzus do have 3400 RPM, but like to cruise around 1700-1800.

I believe you will want the TPS connected. This shouldn't be a challenge, Most Cummins engine have a TPS on them, Isuzus are not a challenge to adapt. I would be happy to share how I have worked through Landcruiser throttle cable and sensor routing in the past. I thoroughly support these products and do my best to help if there's a problem with your install.
What I want to try with the 93-94, but haven't yet is using an adjustable "signal converter" box from Dakota Digital or one of the various other makers of such things connected to the input speed sensor in the transmission. Most of these converter boxes are set up with DIP switches or other means to select the input-output signal ratio. I would use some simple relay logic to setup up 2 or 3 different signal modification ratios with the converter box, each different ratio would be activated by switches on the throttle linkage or manifold pressure switches.
This would do the same thing as add on "chips" for engine tuning, just fake out the input signal to get the factory electronics to control the transmission how you want.
The nice thing about modifying the input speed signal as opposed to toying with the TPS or throttle valve adjustment is the TCU will believe it's behind an engine that's turning 5000 RPM at full throttle and set high line pressure accordingly. The shift points will be artificially low to work with the diesel, but the feel will be the same.
I don't think it would be that difficult to sort out. It could probably be made as a plug in kit.
