We (Westcoastcruisers.com, San Diego, California) just completed the build of a 1996 80 series with a fully rebuilt 1HD-FT engine. Here is a brief documentation of the project. I will be uploading pictures over the next days, but feel free to ask specific questions.
The background:
The truck had a 1HD-T engine in it. I had multiple problems with this engine (some documented on MUD), and finally decided I had enough of it, and threw it out, despite having it rebuilt fully before that.
Then we had the good luck to pick up a 1HD-FT engine from a storage locker in SF. That engine turned out to be almost brand new, but the piston pin in #6 was wrongly installed, so that cylinder had some scoring. So the engine got a full rebuild.
The truck:
The truck is a 1996 US model 80 series that has been re-registered as diesel. Yes-fully legal, yes-with the correct VIN, yes-as the correct year, no-it is not a grey market vehicle (just to pre-answer the usual questions). The truck is fully locked, OME heavy 2 inch lift, front ARB, rear BumpitOffRoad, factory auxiliary tank, dual batteries, Waggongear goodies……..just no useful engine.
The truck has a new H151F 5 speed manual transmission and a HF1A part time transfer case.
The plan for the engine:
Fully rebuild it with all new bearings, seals, pistons with Alfin inserts, new hoses…
Add a Grunter 2 G turbo.
Add a top mount intercooler.
Completely rebuild the injection pump to the specs provided by the good Graeme at G-turbo. Rebuild the injectors.
People that provided essential help:
Michael at westcoastcruisers owns the shop we work in and has enormous knowledge about Toyota diesel engines.
Bob was always there to help.
Pete helped me pull more engines than he ever wished for.
Graeme was super helpful when it came to the turbo and injection pump specs.
Akella4x4 managed to get all the 1HD-FT specific parts we needed at great prices.
TheBigBoy rescued the whole project by going out of his way in getting us a clutch that could actually handle the torque and power of the engine.
Thank you all!
The outcome:
The truck is crazy powerful. I do not have Dyno data, but it is just ridiculous in acceleration. On a long fairly steep grade that I had to downshift to 3rd with the 1HD-T I can now accelerate easily in 5th gear. The temperatures are actually lower than before. On a long and fast highway run the water temp was stable at 180F and the EGTs never exceeded 700F during acceleration and were stable at 400F when cruising at 75mph.
OK, here are some pics:
The block back from the machine shop and the rebuild injection pump installed.
