Hi there,

I searched the forum for some conversions of 1HD engines. I noticed that most people use 1HD-T engines for conversions instead of the 1HD-FTE. The FTE is electronically and I want my car to be as basic as possible, but in Europe it is much easier to get one than a 1HD-T or 1HD-FT. I think because there are quite some HDJ100's around here.
The australian 79's also have 1HD-FTE engines so it should fit, but is it easy to change the 1HZ for a 1HD-FTE? The 1HZ isn't electronical at all, so what is needed for making the fuel pump working? Is there anyone with experience with this conversion?
And I found on the internet that some FTE's have some problems with the fuel pump, is it really that bad or is a conversion to a 1HD-FTE a good alternative for placing a turbo on my 1HZ?
 
My 1HZ has 300 000 km on it, and I don't expect it will last for another 150 000 when I place a turbo. Besides that I need a boost compensator, new injectors and probably new radiator because this one isnt that good anymore. So when I can purchase a low km or reconditioned 1HD I think it will be a better and maybe cheaper option. But I am not sure about that, so I need some advice or experiences.
 
I would look for a 1HD-FT engine, second option will be an 1HD-T .. the think with the FTE it's you don't know how well or bad was it's past life ..
 
I was under the impression that the injector pump on the FTE could be converted so it was no longer electronically controlled
 
Better off in the diesel forum. Most owners who do this swap use the 1HD FT pump on the 1HD FTE engine.
 
please bear in mind that the r151f gearbox does not last long with extra torque from turbo engine

Yes I realize that, but when it will break down I can always upgrade to a h151 or replace the output shaft. The newer r151 gearboxes are better than those who are used in the early 79's aren't they?

Really?! 300,000KM isn't that bad for a diesel engine, especially a 1HZ. Unless it's been poorly maintained, I would believe that engine would have a lot of life left in it and worth rebuilding.

Are you purchasing a full donor rig, or just the engine/components? The only big issue I could see with only purchasing the engine is not having the proper electrical to go with it; unless of course you have a background in automotive electrical systems.

Do you have any photos of your LC? Where are you located?

Not sure where you are but in ZA they actually got worse with time so I would swap both motor and box at the same time ..
 
honestly yet to see one of those R151 to blow .. they might not last 20 plus years .. but I don't thing they are bad trannys, just not that much over build as the old H150 and H151 are ..

Hi Tapage.
Around here the earlier R151 boxes mostly went(less so in the 105 ser prolly due to the diff ratio)in 3rd gear, and only if turboed, or towing abusingly in 5th gear.With the newer 1HZJ 76 boxes, significantly more boxes started failing during normal usage so ..
 
What are the main issues for the electric wiring when placing a 1HD-FTE in a 79? I think the gas pedal is electric on the FTE, while there is a mechanical in the 79 cruisers. Is it much easier to bolt on a 1HD-FT pump on the FTE engine? Or will you face other problems when doing that? And what about the intercooler on a 1HD-FTE, it won't fit in the narrow front of the 79 but will it be a problem to remove it?
About the gearboxes; it is quite easy to get a gearbox from a HZJ74 and a HZJ78, are they delivered with R151 or with H151 gearboxes?
 
79s came out with a non intercooled 1hdfte. Model designation is hdj79. Yes, accelerator pedal is fly by wire (electronic). Conversion is not that hard if you have the complete wiring harness. Hdj79's also have the stronger h150f gearbox.
 
I know some one who did the conversion from a wrecked hdj100 sahara into a fzj105, He replaced the engine and gearbox, so 4 speed auto to 5 Speed auto. It took him ages because the wiring was very different apparently (he had a whole donor car), The sahara had alot more electronics including rear ac unit. Probably doesnt help you much but keep that in mind if you get a donor car.
 
Hmm difficult electronics seems to be a problem in my case. I prefer my cruiser to be as basic as possible. That's why I drive a 70 series...
Better option is to find a 1HD-FT or to replace the pump of the 1HD-FTE for a FT pump. Is it necessary to replace injectors etc. as well in that case?

And about the gearbox; what is the weakest point of the R151 box? Bearings or output/input shafts? And what about the gears itselfs? Maybe it's possible to improve the R151 a little bit? It's quite hard to find a H151 box in Europe I noticed so far.
 
This thread will give some info about injector pump swap.

Hmmmmm. Can't link the thread for some reason. Cut n paste from said thread.

Just off the top of my head

- timing cases are different. New holes have to be drilled and tapped or source FT timing cases.

- injector pump shaft is a different size. FT is smaller so either get the FTE timing gear modified or use a complete FT timing gear set.

- the FTE runs higher injection pressures so either have the FTE injectors rebuilt to suit the lower pressure of the FT pump or run FT injectors.

Hey how are things... have you got a contact for this guy that did the conversion, as I have just started doing the same conversion into a 78 series...
 
If you're in Europe, checkout ebay uk. 80 series are pretty cheap over there. I got one last year and by selling all the extra parts of the 80 series i had my 1hdft for free. It however needed quite some maintanaince, but an expensive engine probably needs that too... You will also have a free h151 that way.
