Hey all,

I'm looking to import an HDJ81 into Canada and wanted to get your opinions on which is the better option to go with? I know of the BEB issues on the T, but my biggest concern comes down to part availability when comparing the two. With the FT only being in production for 2 years is there a big difference in part availability?

If ya'll were going to import one which one would you go with?
 
Yes, very big difference in parts availability. Lots of new parts still available for the HDT including short block and head, very few pars available for the FT. Plenty of info here on mud but have to dig around: @SNLC probably has the most knowledge here in the US on these engines


You may want to seek one with a FTE...
 
I was considering going with a 100 series for the FTE since I don't do heavy wheeling and more of expedition and long highway miles. Thanks for the links to the other threads.

It definitely seemed there were a lot more part availability for the T on Amayama and PartSouq so I thought that might be the case that it had more availability than the FT.
 
I looked at an HDJ101 the other day and it felt nice for sure, might have to seriously consider going with a 100 then.

I agree with Hulsty.

100s are a bit more refined in terms of overall comfort, NVH etc.
100 is a bit more spacious for passengers.
1hd-fte is definitely superior to early 1hd engines.
Overall, better for long highway use etc
 
Agree with the 100 series. More room and more comfortable seating.

I have a 1hdft and have zero issues getting parts. And lots of the parts in the HD series are interchangeable. Pistons, blocks, but the heads are different. They are even a few guys who converted their 1hdfte from electronic to mechanical. Why I don't know but they did
 
From what I've seen so far maintainance parts and auxillaries are still widely available from both OEM and aftermarket. What is a bit concerning is the availability of FT exclusive engine parts. I don't think I've ever seen even one FT injector pump online anywhere and performance shops sell modified ones only with core exchange. Spare engines are also very rare even over here. I guess in the unlikely event of catastrophic engine failures there's always the option of going towards FTE or some hybrid version in between.
 
When I imported mine I specifically went for the FT. I can't compare it to the HD-T but I like it and a lot of the parts are still available and interchange. I think it I went for a 100 I'd just stick to the 4.7 V8 already available in the states. While not a diesel it's one of the best Toyota engines ever made.
 
Yep but the question was where to get one. I don't know what the cost to rebuild an IP is these days but I'd rather have ADS rebuilt one than anyone else doing it, they're proven.

The point was/is new not being available.

Cheers
 
No you are right, I didn't think about it that way. Even with the core charge ~4k AUD wouldn't be too bad for a fresh replacement pump, although I'm sure their supply is very limited as well.
