Because the original poster asked. ;-)

That would be my initial thought too, talk to a Denso shop and ask them to look up the specs of the 2 pumps for comparison.

Apologies for the misinformation, I stand corrected - just took a look at the Toyota CD again and yes the A750 vehicles had the 3.9:1 ratio.... Does the 8" centre from a live axel front fit into the IFS? If so, I might try and source the 3.7:1 from the newer V8 Troopy... Yes, although the Toyota ...

I also discovered that the 2006 and possibly earlier HDJ100R with the 5spd auto had 4.1:1 diff ratios while the 4spd auto HDJ100R hd 3.9:1 diff ratios. Since the LX470 has 4.1:1 diff ratios, I am in no hurry to change them (I thought I needed to change to 3.9). All Aussie HDJ100's with the 5 speed ...

ferrit wrote:Not to mention that if you fit Free wheeling hubs to the 100 series with ABS it causes the ABS to crap out and stop working- the front sensor rings are on the CV's, not the hub rotating assembly.

Only applicable to RFS (live axle) models, IFS are fine as the sensor is on the wheel hub.

Dieslex wrote: As far as I know, front diff locks were not an option.

Correct! No IFS Landcruiser has had a front diff lock as a factory option.

Hdj 79 is good for everything except crossmember ,clutch pedal and shifter so flywheel clutch and box with transfer are all good from one of them only thing to remember is you will lose full time 4x4 and if you put free wheel hubs on your abs will fail 80 series or 105 series petrol or td are the H ...

The FJ80 (3F) used the H150F box, the FZJ80 used the H151F box.

They should interchange / bolt in by swapping bell housings, but the input shaft will be wrong.

Assuming you were in low range, the centre diff lock (CDL) should have engaged, yellow light on dash, and you should have 50/50 front/rear drive. If you were in high, and the modification of adding the non VC 80 series centre diff lock switch to the dash had not been done, then you would have ...

100's with ABS don't run a LSPV.

Perhaps the increased COG and stiffer rebound shocks are keeping the wheels from good contact with the ground?

Got it in one. Apparently the EGR ECU also doubles as the glow plug controller too.

KaMo wrote:Did the manual and auto 1HD-FTE 100's have the same power figures as one another? i.e. Was the engine de-rated at all to suit either box?

Same figures for all 3 trannys. The manual does have a power limiting function via a switch on 1st gear though.

The FJ80 had the H150F gearbox, just like the HZJ80's, but the bellhousing will be different and possibly the imput shaft too. FZJ80 and HDJ80 had the H151F, only difference is that ratios of first and 2nd gears respectively were taller than the H150F, and the input shaft is bigger. No 80 series had ...

Sept. 2007 according to Redbook.

Keeps pulling to 4800rpm

Does it maintain that 25psi at 4000 - 4800rpm?

Depends on what sort of reliability you're after, power and fuel efficiency you expect, etc. The 1HZ in the 100 is more frail than earlier models, and has to work harder dragging the larger truck around. The fuel system ideally needs to be in tip top condition, as the 100's are getting on nowdays ...

The 105s at the mine I used to work at got a serious flogging 24/7 (1998 models cut down to twin cabs with trays) and none of the gearboxes failed, according to the LV fitter. But they were NA 1HZs more than likely de-tuned. And if they were running in low range the torque loading is substantially ...

The gearbox in the HZJ105's is the R151F, same as TD Prado and Hilux, i.e. much lighter vehicles.

In the HZJ105, behind the 1HZ and particularly with aftermarket turbo, larger wheels, more weight, etc, etc they give trouble as they tend to be a little overstressed.

All 105's run 4.3:1's.

Inlet open 8deg BTDC, close 36 deg ABDC
Exhaust open 51deg BBDC, close 5deg ATDC

The OP Tom stated he's already running 11psi max. How much boost do you suggest he to run to drop his EGT's?

The turbo which toyota matched to the 1HD-T (essentially the same engine, just different injection and head) is too small? Well the 1HD-FT and 1HD-FTE are "essentially the same" engines too, yet no 1HD* engine runs the same turbo. High EGT's are caused by not enough boost, turbos that are too small ...

Yep, and an oil analysis isn't going to help the diagnosis either.

Bite the bullet and rip the head off.

If it is all working correctly, then yes it will lock in 3rd or 4th gears.

You should be able to see all this happen on the tachometer while driving.

I think the fact that you can hear the miss through the oil cap means the compression is getting into the sump. I'd guess cracked piston (unusual) or broken ring(s).

The CT26 is smaller than ideal for the 1HZ, causing greater heating of the intake charge and less air mass, therefore higher EGT's. It will be better than no turbo, but not as ideal as the right turbo. The fitment of a boost compensator (BC) means that they can tune it for higher peak power (exactly ...

They're essentially the same box, however the 1st and 2nd ratios in the TD box are taller.

You'd need to change your clutch plate to match the larger input shaft.

Possibly, but there are many different CT26's, even the 1HD-T and 1HD-FT units are different.

What vehicle is the R151F from?

I think the rear HZJ105 R151F housing is different, so it matches the HF series t/cases and makes it equivalent in length to the H boxes.

dot know if they still do??

Any details Jonathan? I know they have mentioned it, but I've never seen or read anything more.
