troopy engine and gearbox change

Have a read of this thread, it's the same conversion done to a 105 Series.

1HD-FTE into 105 Series

G'day Ian
Can't comment on the engine change - other than "lucky you".

I have a 1HZ Troopy which now has a turbo gearbox/transfer case. The drama of this conversion can be read on Lcool here

It's been a while but I think the H150 rather than the H151 might be the one you are after. From memory the shift levers on the 150 are closer to the position of the originals. Mine are only slightly forward. You will need the floorplate from the donor vehicle as well.

Pitfalls? Biggest one is believing anyone who says conversions are a "bolt up" to your truck. :)

On the 80 series it is a straight swap as all wiring is already there. Not sure about 70 series
Exhaust engine pipe has to be changed.
R151 Gearbox. If length of gearbox, position of transfer case and mounting are the same as H151 then original mountings and tail shafts should be ok.

I had no problem swapping the engine and transmission in my 80series.

Good Luck

Hi Ian,

I am in the process of doing just such a conversion to my 1HZ 75 series.
The engine I am using is from a '97 model 80 series and the gearbox from a '03 79 series. I have the flywheel and clutch from the doner 79 because as you may know the clutch is about 1" larger in diameter, although the existing flywheel can be machined to suit. I am using a new clutch and pressure plate just to be sure. Just make sure you get the right spline for the H151F input shaft.
Because the 1HDFT has no more electronics than the 1HZ the wiring appears to need very little modification. I do have the engine wiring harness from the 80.
As you probably know the starting glow system is different on the 2 engines but everyone I have spoken to says the intake heater on the 1HD-FT is not needed unless you are in extremely cold climates. This does not usually happen here in good 'ol WA....lol..I am going to leave it disconnected and see how it goes, if no dramas I will remove the heater element altogether.
I have the cross member from the 80 that supports the g/box so minor changes may be necessary if I need to use it.
Not sure about the R151 but to swap from a H55F to the H151F the tailshaft length needs changing.
The radiator will get rodded to make sure it is in good condition and the aircon condenser will be repositioned so that the radiator is getting the coolest airflow possible.
As others have said fitting an engine into an engine bay that was not originally designed for it is always going to present a few (or many) challenges depending on the engine in question. The inquiries I made before purchasing anything tell me this conversion is not rocket science if you have some reasonable mechanical nous.
If you have a look on lcool a lot of good info is there, you need to join but it is free.

Anyway good luck with your conversion

Ian,
If you have not done so I would join LCOOL as there are many people there who have done conversions and as it is dedicated to Landcruisers you will benefit from the wealth of knowledge.

LCOOL
