    Years/differences/suitability of 2H changeover engine.

    The cost of buying and installing sleeves then boring. Sleeves are not machined to be a install and run setup. Parent bore only requires machining. Plus pistons and rings for both scenarios.

    100/105 series diesel gears

    Still available on this end through Partsouq. I've also used drivetech gears in 3.73, same as Marks and PDI I believe, with no problems at all. they set up very easily, like OEM. They are Japanese.

    Auto FZJ105 are 4.3. Auto HDJ100 are 3.9, aswell as all vdj76/78/79 from 07 to current.

    1hdft and 1hdfte cylinder head differances?

    Just an FYI, you can use your FT valve cover on the FTE head. I ran one on mine for years. You just have to plug the unused holes with 6mm grub screws and a bit of sealant.

    Welcome to my 1HDT rebuild nightmare.

    That looks like a snapped crank to me. There are a lot of these running around and it's not a common issue.

    Possible turbo oil leak

    Like gerg said, work that engine. Give it the best possible chance to seat the rings. Some rebuilt 1hzs here took 20k kms for the oil usage to settle down. They were using as much as 1L per 1000kms

    VDJ79 H150 into HDJ80?

    That all depends on what the H150f is out of and what its going back into. The H150f out of a 1hz 80 series has small input shaft, fine spline. The H150f out of a HDJ79 has the larger input, coarse 14 spline. The H150f out of a VDJ79 has the same coarse spline as the HDJ but is longer in length...

    1HD-FTE maintenance and proformance in my hdj79

    I found my boost cut at 15.5psi on my HDJ. The computer will adjust for fuel upto the boost cut limit. I found the gains to be marginal.

    VDJ79 H150 into HDJ80?

    Will need to use your input shaft, front bearing retainer and bell housing from the H151f and swap it into the VDJ H150f. Transfer case will bolt on.

    What happened to my 1HDFT? Taking bets

    Incase you didn't see them before

    What happened to my 1HDFT? Taking bets

    I would strongly recommend new pistons too. Pics 2 and 4 show heat related cracking of the pistons at the combustion bowl. If this is left to its own devices, they will crack all the way through. This is what the end result is Cracked completely in half.

    RTH: GTurbo got lazy after highway drive, slow to build boost, lower boost levels than normal

    I'm gunna disagree slightly, but with oil on the bearings it should spin more than 2 revolutions

    Jrace Industries 12HT exhaust manifold

    JRace is just up the road from me. He does outstanding work. Check out his facebook page

    My rebuild thread

    The injection pump is gear driven off the crank. The timing belt drives the cam off the injection pump so if your trying to turn the injection pump, you're trying to turn the whole engine. I personally don't think its the root cause.

    The 2H/12H-T/1HZ/1HD-T/1HD-FT Gturbo Alternative Tech Thread

    This has more to do with the lack of fuelling than the turbo itself (emission control). Bring in more fuel down low and you'll be suprised what that std ct26 can do. For a mild upgrade, run a ct20b of a 1hdfte like dougal said above

    My rebuild thread

    Remove the oil filter and cut it open. Remove the media and lay it out on the bench. Check for particle buildup. If you find any, pull the sump and inspect all the BEB's.

    1HD-T rebuild and transplant into HZJ 105

    This is a post off the LCOOL forum. It may shed some more info. There has been much discussion over the years on converting an R151 to a H150 or H151. Some info good some right of track, her are some things I have just learnt by doing the conversion. If you have a HZJ105 STD you need a h150...

    1HD-T rebuild and transplant into HZJ 105

    You are correct. The HZJ80 (1HZ) has a fine spline H150f. The HDJ78/9 has the coarse spline H150f. (Direct fit) The FZJ78/9 also has the coarse spline H150f. (Need 1hd bellhousing) The VDJ76/8/9 has the H150f/H152f but needs the 1hd bellhousing and input shaft. A GCC spec GRJ79 will also...

    1HD-T rebuild and transplant into HZJ 105

    Just as a heads up, The H150f out of a 1hz 80 has 21 spline input shaft. The H150f out of a Hdj78/79 has the coarse 14 spline input shaft. The Hdj7x/ vdj7x never had the H151f box not that there's much difference. If your looking for a h series box, look for a box out of a hdj78/79...

    Landcruiser 100 lacking power and using lots of fuel

    Check the boost line pressure damper and hose for cracks, these quite regularly fail causing the boost signal at the map sensor to read low, thus not delivering correct fueling. It causes the exact symptoms you are describing.
