ARCHIVE 2UZ-FE to H55F - Interest?

[Well Sorted]

Hey guys, I've recently started up a business focusing on modern performance upgrades for classic vehicles. I am of course into Cruisers but not exclusive to this market, however I do want to work on some products and support things in the Cruiser world where it makes sense and I see opportunities.

I've had an idea in my head for a few months that I can't shake which is to develop the necessary components for mating the 2UZ-FE to the H55F. I found a source in Australia but they are too busy to do more than the occasional one-off job so I'm contemplating designing the adapter bellhousing and clutch/flywheel bits myself. Sourcing bellhousings will be an expensive proposition so before I get too far along I'd like to get general feedback of who might be interested in this setup.

I know the LS is a great option just based on my own experience building and using my rig, but for folks looking for a little more pure swap with a Toyota engine I thought this might be an interesting offering. Let me know what you think, or specific questions if you have them.

The price is right on the used dressed long blocks and rebuilding one wouldn’t be huge deal.

The marks adapter kit for an ls has some issues that concern me with that adapter and we’re validated by someone in the know. Get in at or lower than that kit and you’re on the right path.

I’d love a mount system, bellhousing, fan clutch/shroud and accessory jumpers to work with ac and ps.

More options is always nice... but second hand 2uz prices are pretty high relative to LS engines... plus wiring is more complex, less after market support etc.

I personally wouldn't bother but I'm also the sort who doesn't care what badge is on the Engine

@ddelong6767 Post up in the 100 series forum, there might be alot of interest in an Automatic to H55 conversion there

The question is: Will the H55F be a good fit behind a 2UZ-FE? Torque-wise as well as final gearing in high range and low-range wise.

There is a reason Toyota used the H151F behind the 2UZ instead of the old H55F. The H151 would be a plug and play unit and it is mated to the HF1A vs the BF1A transfer case.

And this is going to be an expensive proposition for most 6x series owners.

75% of 60 series owners gripe about the cost of a dizzy cap and rotor from Toyota. This demographic will egg you on to develop something like this only to find that you are the one holding the bag when it's all said and done and 2 people out of the 100 that egged you on actually buy something from you.

Keep that in mind too.

Good luck. This sounds like a cool project.

Good points Beno, I've thought through some of those elements. The real hurdle is the investment cost of making H55F adapters and associated retail price of the pieces versus buying the H151/HF1A. I think the Cummins R2.8 is an interesting case study on what people will really spend on the old rigs for some of these more modern engines.

My gut says there's probably not enough market to justify this project, but that's why I posted this thread. I hear you that expressed interest doesn't translate to actual purchases at a high rate, seems like many manufacturers I've talked to say it's on the order of 10%. But maybe there's a pent up demand for 2UZ swaps that I don't know about...

I've seen and been in your feet many times in the past in different (but similar) capacities in my professional career in the Land Cruiser community.

The reason the R2.8 is so popular is the marketing IMO. I think the marketing and money thrown at this by Cummins is what is driving interest in the R2.8 (along with shops that are pitching it as well since they have a direct relationship with Cummins).

Personally, a Cummins in a Toyota Land Cruiser is blasphemy.

1uz is a lot cheaper than both LS and 2uz.

Also- Obd1 would be tons easier than both LS and 2uz.

Imho- most people don’t need the expensive h55 overdrive as most will be running rubber overdrive.....and will want to spend on tcase gearing options.

so cheap widely available 1uz engine/ dirt cheap 4spd / and let people figure out how deep into gearing options/expense with Orion’s/atlas’s / toyboxes /diffs expense they want to go behind a budget modern balanced engine. Short v8-short 4spd.... lots of gearing/price options behind. If you can keep the Used 1uz/used4spd/adapters/wiring and clutch stuff less than the cost of rebuilding an F,2F,3f,1fz.......you have a short plug n play all Toyota option with 250hp/250tq for 40/45/55/60/80 and let people go to town with whatever gearing suits their needs or budget.

Adapter/ wiring and a touch of desmog/simplifificatiion on the obd1 1uz

Coming from the Land Rover world, I have seen vaporware parts before. However a few guys build things for their own rigs and then has a few extra made.
I would use this as a feeler to see who is interested.
If you are doing this yourself or for someone else as a swap, make a few extra kits and see if they sell.
If they do, and they problably will then see what the interest is and make a few batches
This is how I know one guy did it for Mercedes Om617 to land rover gearbox adapter. He made like 3 at a time.

 

[red66toy]

I have seen this a couple times before and nothing comes of it which makes me think the math never works out to produce such a kit or adaptor. I think this route will forever be a one-off do it at your own risk swap. A 2UZ in a 60 would be awesome!

So why cant we get that combo here then? 2UZ-FE and H151? I'd love to do this in my 62. Myself and @bdyer12 have talked about this conversion, not the H151 but the H55f.

I can get you anything you want to pay for.

Damn I should have figured you could, then I'll start working on my bank account! Really would be an amazing set-up.

I am currently working on a 1HZ-R151 conversion to a turbo 1HZ-H151F conversion in a 105 series.... Talk about walking the tight rope!

Didn't CastleMaine in AUS make this bellhousing and kit? IIRC either Tucker or Delancy comes to mind in a thread A LONG TIME AGO..

I have a OEM 2UZ to A440/442 bellhousing (still available by Mr.Yota), so I'm sure the monster exists somewhere for a 2UZ to H55F in the aftermarket world in Oz or SA...

THIS..... Unless its something I personally want... I don't make efforts anymore. Out of 15... you'll sell 1-3 and the other 12-14 will sit and collect an inch of dust and take up space over the next 5-10 years... I won't make things over 2-300.00 anymore unless I have 10-20 guys that are prepaid with a NON-REFUND policy in place... It's just not the 60 guys... it's all things cruiser anymore.

Good Luck Doug,

Jason

1UZ and 2UZ will use the same bellhousing ..

I have the chance to put my hands on 1UZ from an GS400 and I'll love to put that engine on Tencha ( with my H55F ) mostly coz the lower gears on the BF1A .. but my main barrier isn't the clutch thing .. it's the harness ( simplified ) to use the UZ out of it's OEM platform ..

 

[gregnash]

Hasn't that been the biggest hurdle in the past, the fact that the ECU/PCM must be modded to allow for the engine to run outside of the normal application and shutoff various items/sensors? @reevesci I thought you had looked into this at one point and your programmer/modder said that it would be a huge effort.

Thanks for adding to the discussion Jason, that's pretty much my conclusion on this. I may still do it on my rig using the Australian parts but I don't see the market being big enough to be worth the effort. Maybe I'll be able to support others who want to go that route with motor mounts or something simple like that, but a full adapter effort doesn't seem to have any business case behind it.

@beno - if you want to shoot me a price for an H151F/HF1A combo I'd be interested, but am afraid of what it will be...

As the saying goes, "if you have to ask" ...

New OEM parts, not including shipping and the like, is well over $6K for the H151F/HF2A or HF1A if you want to part time the sucker.
