1hd-ft swapped 80 with high get

I can't figure out how to get an Allen wrench on the Allen bolt on the top cover of the injection pump without hitting the intake manifold. Maybe I missing something.

Very common issue, especially if your running a bit more timing which gives even less clearance between the manifold and the pump. I often had to use vice grips on the two cap head screws closest to the engine to remove.

I've always thought the timing was my egt issue. I was told the timing was good. May have them check it again to confirm with Toyota specs.

Tuning and timing. Combination of these.

People wouldn't build up an old school gas engine and expect it to perform its best without setting the timing, and tuning the carburettor.
Same concept. Different hardware.

Diesel engine is no more mysterious than a gas engine, it just takes some digging to find and understand the info that's out there. The. Finding good info part is less easy.

37" tires will definitely make it feel slower, my brother's HDJ81 is running 33's and maintains 60-70mph on hills, usually running 1250-1350ºF. If I had to guess I'd say there isn't anything wrong with your engine or drivetrain, these things run hotter than many people think in stock form, especially traveling in North American highway conditions. If you really put your foot into it on flat ground does it move out pretty well? Short hard pulls at high EGT won't cause any harm, I've seen north of 1650ºF on my TDI a couple of times and run it at over 1300ºF for extended periods, though I try not to do that.

Having owned a couple of 2L-TE powered LandCruisers I can sympathize with constant concern over EGT's and having to keep backing off the throttle. Ideally I would recommend fitting an intercooler, but in the absence of that you can turn up the boost a bit and adjust fueling to keep exhaust temps in check under heavy throttle. It isn't super well tuned, but my brother's HDJ81 is fairly quick (by diesel LandCruiser standards) and doesn't run scary hot. Definitely much faster than when I owned it in stock form.

Getting passed by all and sundry is pretty much a fact of life for us diesel LC owners! I generally cruise at 75-77mph (around 120km/h) on the interstate around here and still get passed regularly by almost everyone, including semis. They're the only ones I catch up with on the hills.

They dont know whats coming once we get over the hill though. Ride that downhill like a skate board.

Wanted to update this post for things other folks should consider. I have the truck back and it has power. EGTs are normal. Max EGTs on the way home pulling up a long steep hill was 1150. The pump was pulled and the mechanic discovered that the injection pump shaft and shaft key was not properly seated with the gear. This was causing the pump to jump in and out of time and create my issues. With the injection pump key not being properly seated it damaged the injection pump shaft, which had to be replaced. Once the damaged parts were fixed and everything installed properly, the truck runs and drive great.

Good find, good mechanic

Los of room for more fuel if you decide you want a bit more power.

Another issue that resolved itself was the transmission. Before the latest fix, the transmission was shifting hard and holding in second and third gear. The original mechanic had no clue what was causing this issue. I thought it was the solenoids in the transmission. I had the solenoids replaced but it didn't solve the issue. I almost replaced the transmission. Once the pump was fixed it solved the shifting issues and I realized I wasted money on having the solenoids replaced. Money spent, lesson learned. It's shocking how the injection pump will cause all kind of issues.
