Well, a 105 with a 1HD-T does exist, albeit that
Mister Blue did not come from the factory that way.
I bought the engine a a place that specializes in JDM parts and I was told was that it was about a 120K. So far I have no reason to question that. I did drive the 105 with the original 1HZ for a time and it just would not keep up with ordinary traffic. My intention for the truck is as a daily driver for the rest of the time I am in Dubai, so the 1HZ just was not viable.
So I had a couple of choices: install an aftermarket turbo or upgrade to a contemporaneous Toyota engine. I chose the latter because the local annual inspection is pretty tough and the rules around getting approval for an aftermarket turbo are murky. Mister Blue has a factory Toyota turbo, and I am hopeful that no issue will be made of that at the next annual.
I had a choice between a 1HD-T and a 1HD-FTE--price was not materially different. I chose the 1HD-T because I did not want to mess with trying to integrate the 1HD-FTE ECU in this old truck. The 1HD-T is basically stand-alone. There are no computers and the diesel pump is mechanical. It would have been nice to have the extra power of the FTE, but all-in-all I am happy with my choice.
Yes, a Yaris can still pull away from me at a stop light, but at least it is not so slow that I have people honking at me.
If you end up with a 1HZ 105, which I do recommend, and you live in a location where modifications are allowed by the local authorities, I'd go with a mild turbo and accept the uncertainty around longevity, but I'd also invest in a good EGT and boost package so you can stay aware of what you are doing. I happen to have gotten one of these installed in my
1991 diesel pickup in Florida by
@cruisermatt and from what Matt and my son say, it is a different vehicle. I'm shortly headed to the US to help my son (under Matt's guidance) change the clutch. The Safari turbo kit came with a heavy duty clutch but we did not put that in in the first go round and my son reports slipping in higher gears.
