Cummins and Isuzu 80 series kits

[Wheelingnoob]

Yes they are but a toy diesel is about the smoothest running diesel out there for a truck application.

I've seen A440's fail behind the 6.2 GM which is much more light duty and way smoother than either the Isuzu or the Cummins.

That said, i'm not saying that it won't work, in fact i'm very interested to see if it does.

If it doesn't a rebuild and extreme valve body and extreme TQ converter after about 4k should make it pretty bullet proof.

Yep I totally agree with you.

I already have an extreme valve body for a A440 and a lower stall diesel torque converter. I will be sending the TC off to get rebuilt and tweeked to reduce heat build up. So the two together should help the A440 handle the added vibration (I think its actually the two power pulses per revolution that is hard on them).

The set-up I have described above should be good for the power I plan to run out of the 4BD (160-180hp). I also have most the $$ mods already for it so its worth a shot. I'm not trying to make a land speeder I am mainly motivated because of economy (range on a tank of fuel) and simplicity of the engine. Up here there are lots of places I want to explore and see but with 250kms of range in a tank off road I can't do it, I would need to take to much extra fuel.

If the A440 cant handle it then I will look for a non electric A442 out of a JDM 81. They have there weaknesses too tho.

What about a manual Conversion or those with a manual gearbox ?

These Aisin transmissions are some of the more reliable automatic transmissions made.

The power levels most people are looking at here aren't pushing the limits of anything.

The stock A440 converters are the only part I would suggest anyone upgrade as part of the diesel install. The A442 converter is much improved.

Most people are not doing this to put a 300 HP 12 valve in their 80. They're doing it with engines around 160 HP and 400 lb/ft. Reliability and economy are priorities, not seeing how far they can shoot the rear axle pinion into the pavement doing a boosted launch on 44's.

I am not familiar with stickshift 80's nor the available engines in markets where stickshift 80's do exist. There's a possibility we could support these, but we're starting with what we know and supporting diesel conversions in the US where diesel SUV's and light trucks aren't available is our primary mission.

Hey All,

I've purchased an adapter for the 6bt from Dustin at Allmaras Machine.

I've got a 1993 FZJ80 with 174,xxx miles, I'll have the engine by next week plus motor mounts and if all goes well, the engine will be in the truck by the following week. Sooner, if I have time.

All work is being done at a professional, full service custom shop. I'll post pictures and results as I have them.

Frankly, this is a dream come true. The fact that I don't have to screw around with the drive train makes this feasible. Not just monetarily but, I don't have the time or patience for all that BS.

Who is doing your work? PM me if you aren't comfortable posting their name.

Cody C on this forum has a 6BT/NV4500 in his 80. He's had issues with wrecking the stock R&P in the 9.5".

Too much skinny pedal, and dropping the clutch on hot pavement with 37's may have had a part in it.

I have killed two R+P's though, the other was after wheeling in in -24 celsius weather. And a dodge clutch fell to pieces in the bellhousing a couple months ago.

When I bought the 80 it had the A440f with an aftermarket torque converter (wholesale auto I think).

The A440 worked well and held up to wheeling, but the shift points were a bit off, I probably could have adjusted the shift cable but didnt think of it.

I broke a few flex plates on it, which I believe were the result of a poorly built adapter plate, which appeared to be part of a toyota bellhousing and a dodge trans adapter maybe. Having broken a few custom built flexplates I came to the realization that I had to look at a different solution. This the NV4500/AA/split case.

Having said that, the A440f worked without fail while I had it, but I prefer the 5 speed nowadays.



Oh yeah, if anyone wants to buy the old A440f with the custom torque converter off the 80...


Too bad, I sold it over a year ago for $400 and it sat in the classifieds for well over a year.

What setup is easy to mod a lil I know the 4bt u can turn up the juice easly but how about in Isuzu 4cyl I'm thinkin 4 cyl diesel should be plenty and I'm sorta a noob what auto is in the 97 fzj80s

Its a full custom shop I'm closely related to.

See our URB, interior tire mount and DIY videos.

We have plans to build more, take on outside jobs once this one is done. If that is what you are interested in. I'll post pictures when complete.

Absolutely, I'm not planning on entering my 80 into a truck pull competition!!!!

I want the economy!! I want a diesel!!

Can you guys make an adapter that will allow an ATLAS transfer case to mount up to the FZJ80 series transmission?

This is getting far outside our market.

Why doesn't Atlas support FJZ80????

Answer:

The initial development costs are more than the product can net.

Max,

Let us know when you get ur swap all buttoned down. Whats ur time frame on this project? I'll make the drive north to check it out!

I'm looking at having the motor in the truck by next week, running and driving the following week?? You all will be the first to know.

Maybe we can meet each other at a Cascade Cruiser event.

If I'm reading some of these posts correctly I see that some are asking to put a manual behind their 1FZ. Are all of you wanting to do the NV4500 or the H55? Doesn't the H55 come behind the 1FZ in some countries? Why would you need an adapter for this? NV4500 because of cost?

Well, the NV4500 already bolts up to a cummins, and AA makes an adapter for the 60 series split case, as far as the isuzu goes, not sure if it will bolt up to a NV.

A 5 speed is a nice thing to have in an 80 IMO, and I think the isuzu with a 5 speed would be a great combo, especially with the AWD for 6 months of the year up here.

If I were doing another swap, I would definately look into the suzy motor or maybe a mitsu.

There was a thread where someone twinned a suzy motor in a ford half ton, then later went to a blower and a turbo, cant remember the site though.

 

[AppleTech]

any possibility of making an adapter to fit an NV4500 behind a 1FZFE??

It would be a new cast bellhousing and billet flywheel if we were to do it. In order to cover the up front investment in casting there would have to be a demand for them. If there were ten interested in the initial run I could keep costs reasonable and make it happen. If it's just 2 or 3 I'd be upside down in casting costs for a long time. You can PM or call the shop if you'd like to talk about this.

I've been thinking about this and have already roughed it up. I'm just looking for a used Dodge NV4500 to take final measurements and take the designs somewhere to get them cut. My design (simple in nature) would utilize the A343 bellhousing and an internal slave, at least my initial design. Once I have my hands physically on a NV4500 and not relying on internet heresay, I'll be able to determine the best adaptation method.

This adapter would center on the bellhousing and the NV4500 front bearing retainer to ensure proper fit.

I think I've got all the electronic issues worked out (in theory).

NV4500 for the price of the tranny and the options to run a myriad of TCs via AA.

Phil, I might know a guy with the NV4500 dimensions your looking for, plus the IFZ, A343 and A442/A440 dimensions. He has machining centers and CAM too

 

[RockJock82]

What kind of power will the Toyota transmission hold up to? Could they handle a mild built 4bt? I'm not thinking of compounds but that would be fun. This is an interesting idea and makes me want to build another cruiser. I have built a few Cummins, 6bt and 4bt's they are great motors and simple to work on. Again the shakes of the 4bt can be remedied by balancing the motor.

 

[cody c]

I am willing to bet that if you made 10 NV4500/1FZ adapters you would sell them within a year.

BTW, the NV4500 has a removable bellhousing and an adapter plate to the cummins engine, for your CAD/design you may be able to grab a bellhousing or adapter, though Im guessing you would still need the whole trans to get center on the input shaft.

The NV4500 is a great transmission IMO, and changes the driving experience in an 80 greatly.

That reminds me, Ive got a slave-master w/resevoir hydraulics for an NV4500 I need to put in the classifieds.
