1hdt

Hi, And here I am thinking with my buttons about what kind of power upgrades or even "raw HPs" would the stock clutch handle. In my case I'm running a custom clutch based on the stock one but it isn't all that much aggressive then the stock one. Engine wise I'm running stock CT-26 @ 15Lbs...

Just pulled an injector for replacement and it looks like this. Hard to tell if it's oil or some sort of fuel sludge. Should I be concerned?

Can the oil filter from the 4Runner/Tacome/Tundra/gas Land Cruiser (Toyota: 90915-YZZD3) be used in the 1HDT engine? I have a lead on a box of them for a decent price and wonder if they can be used? Cheers,

Hi. Iv got a 1990 HDJ-81 With the 1HDT. How do you get the oil pressure sender out? I need to replace it. Is there a trick to this or do I just need smaller hands? Any help would be great. Thanks. Michael

These Injectors have SOLD! I have a set of 6 injectors (USED) for the 1HDT engine from our 1991 HDJ81 (Japan market, RHD) Land Cruiser that I am selling for $350, plus shipping costs. The injectors have NOT been tested, cleaned, or reconditioned. They are being sold 'as-is' in USED condition...

I was hoping someone could help me out here with a diagnosis and hopefully, an easy fix. I noticed that the corrugated, bent portion of the air intake hose that is AFTER the air filter (probably a foot or so below the air filter along the air intake hose), but BEFORE the turbo, is wet with...

Hi all, Timing belt let go on the 80 and did not end well. Engine is being rebuilt. I started a thread over on 4wd action and thought it would be of interest. Link below. If this breaches rules I'll remove and copy content over. Any feed back welcomed. Cheers Mat...

Following @IanB I'm reposting a question here

Hi, Just a quick question, from what I've found a turbo back exhaust for a 1HDT is the same as for a 1HDFT, am I right? Same turbo flange and mounts. Thanks Cheers

Does the STANDARD aneroid pin allow full fuel at full boost (thinnest part of taper)? Or is it still restricting it in comparison to the main set screw setting? As such, does rotating the aneroid pin affect any change at FULL boost when the pin is fully depressed? I am only talking full boost...

I purchased a kit that included the copper washers but not the o-rings, and I'd rather not pay/wait for shipping from Australia to get them. Does anyone know the dimensions for the 1hdt injector o-rings? I heard Viton rings might be a good upgrade to what Toyota provides. Is there any truth to this?

I decided to perform some minor cylinder head porting and polishing when my engine was apart for a minor overhaul. Researching the forums and looking at common practices with high performance motorcycle and car engines I decided to do some basic cylinder head modifications. If you have any...

Hey guys, I installed a 3inch muffler on my HDJ80 past weekend, and well here are some pros and cons that I found... Pros: 1- More Power, when accelerating the car just accelerates beastly. 2- More torque, when going uphill, it has more torque to stay on a High gear. 3- The sound... It is...

I have a 1hdt that has done 6000k since full rebuild. It has been blowing blue smoke on start up and at idle since first got it back from Reconditioners. Although it is not using much oil ( 200-300mls per 5000km) it is blowing smoke out oil filler and rocket cover bypass if you open them but...
