FJ60 diesel conversion questions (1 Viewer)

[Mike S]

In the next year or two, my FJ60 will need an engine refresh. As I see it, I have two preferred choices, rebuild the current 2F to blueprint standards, or go OEM diesel. So I have some diesel questions...

1. I am thinking that a 6 cylinder that meets or exceeds the performance of my current 2F is needed. 1HD-T? Any one done this swap?

2. Registration in California - can a diesel conversion be registered without an act of God?

Thanks for any and all help and suggestions.

1HD-T is a great motor, it is the turbo charged, direct inject version of the 1HZ. The only problem these motors had was with big end bearing failure. It is often recommended that these are replaced if not previously done. The swap would be just as straight forward as a 1HZ except for the added turbo plumbing etc. Still not very difficult i think.

A turbo'd 1HZ or 12H-T would also out perform a 2F and may be cheaper, not sure though.

I have a 1987 HJ60 that was imported into the US, then I bought it. Im having it restored at Radd Cruisers on Vancouver Island BC. I chose a 1HZ for it. Great engine for sure. Cant go wrong with a 1HZ or a 1HD. The 1HD is going to cost you much more.

I prefer the 1HD-FT in my HDJ80 myself

I am looking to retain the H55F and split case that I have, and understand that the 1HD-FT has electronic controls, which would complicate installation. Great engine tho'.

Youll need to change the gearbox or change the input shaft if you plan to use the 1HZ or 1HD-t.
The 2H or 12HT diesel 6s will fit your gearbox.
The 2H would have less HP than the 2F and the 12HT (turbo)is not easy to source.About $7500-$8000 in australia.

You will need the computer and all the asscociated wiring from a donor for the 1HD-FT and probably the trans.

The 2H will feel like a bit of a slug compared to the 2F. 12HT would be a relatively easy swap if you can find one.

what about the 13bt in a 60?
i think it's a great motor for the 60.....

Mike, AFAIK the 1HDFT does not have much in the way of electronic controls. Maybe you were thinking of the 1HDFTE? Either one will mate with an H55f and split case if used with the correct bellhousing, but your present gearbox does not have the correct input shaft anyway. The only desirable (IMO) one that will bolt to your H55f is the 12HT.

2. Registration in California - can a diesel conversion be registered without an act of God?

The way I understand it is that CARB will allow diesel conversions as long as the engine has been installed in a US vehicle. gifu (Brian S.) has a better insight into this matter.

That said, there was a guy doing 1HDT swaps into several US 80 series in So. Cal. a while back and he was able to register them. I don't know how he did it though.

I am not yet fluent in Toyota dieselspeak. I do know about the input shaft problem. Sheldon at G&S said that there was an Isuzu clutch that helped resolve the compatibility problem. Failing that I guess a different tranny (H55F or H151?) would be required.

Trying to preserve the investment I made to date in upgrades to the truck. My 2F runs fine, but when it strats to die, I want to have a plan, and Diesel is very appealing.

Don't know about other possible issues, like 24V vs. 12V, adequacy of the 2F radiator and compatibility, any difference in weight and impacts on suspension. Etc.

Thanks for all the repsonses, More research is required, I think.

The Isuzu clutch only solves the input shaft spline count problem for a 1HZ version of the H55f gearbox when used behind the 4.2L turbo diesels (1HDT, 1HDFT or 1HDFTE.) The 2F/2H version H55f input shaft will be about 1/4" short if used with the 1HZ bellhousing.

No problems, Mike. Ask anytime

Newbie here.

Mike, I'm somewhat in the same boat, as I'm starting to explore a diesel conversion for my FJ60 here in California, though my motivations are somewhat different; wanting better mileage and the option to run bio-diesel somewhere down the line.

Currently running a TBI Chevy 350, 700R4 tranny, Toyota t/c (originally from behind a 3 spd), and a GM203 gear reduction box, and might be willing to swap out this entire drivetrain to go with an oil burner. I went through the local smog referee relatively painlessly when I bought this cruiser out of state and brought it in. A testament to the thorough work the previous owner did.

Have you been able to find any info on registering a diesel conversion here? Lots of rules for engine conversions here, but any that I can find talking about diesel conversions. It'd be stupid to have the same rules for a diesel conversion (so they probably are the same rules), especially since diesels don't have to be smog tested here.


thanks,
Herb

I just don't know. A Diesel swap to a 4.2 L engine would cost more than double what a rebuild of the 2F would cost, but I would expect it to last much longer, and give better mileage and torque.

If we can find someone who has done a swap and legally registered in CA, it would be helpful. I will talk to Mudrak, and see what he says...

Jeff Bryant in Susanville runs a 1HD-T mated to an H55F. He used an engine sourced from SOR and did the conversion himself, with a lot of info and advice from a couple of legendary sources. He's had this conversion since the late 90's and having driven his Land Cruiser for a lot of miles, I can honestly say it's one of the nicest diesel Land Cruisers I've ever had the pleasure to experience. That is the route I wish I'd gone when I decided to do a diesel conversion, but the price of the engine and the hassle of the non-US parts took me in a different direction.

 

[crushers]

for better performance and ease of installation i would suggest the 1HZ with a aftermarket turbo and PI.
the 13BT will give you the best fuel economy and pobably the cheapest route.
just my unbiased opinion
cheers

Contact info??

Do you have contact info for Jeff Bryant? I would drive to Susanville to see this cruiser and talk to Jeff...
