The project idea and concept arose after returning from a trip early 2010, from the Murchison area in Western Australia and finding that the old petrol 4.5L engine wasn’t up to the task anymore. With the desire for remote outback travel the idea of a turbo diesel wagon was more a necessity than a want.

The new wagon had to meet the following criteria:
1. Turbo Diesel and automatic
2. Must be able to carry 2 adults and 4 kids comfortably
3. Live axles front and rear
4. Coil springs all-round
5. Part time 4wd
6. Easily available spare parts and accessories
7. Fit down any track in Australia
8. Cost no more than $40-45K for a complete touring 4by with all the bells and whistles (could be dreaming)

I started looking at several different options, selling the FZJ80 and buying a HDJ80, finding a HDJ wreck and doing a conversion, upgrading to a TD 100 series and finally the 6.6L Duramax conversion into an 80 Series.

A few Duramax conversions in Patrols had now been completed by this stage (Heath...) and the output figures were very impressive. I managed to get a pretty sweet deal on a new LMM and 6 speed Allison with all accessories so the decision was made to buy a salvage FZJ80 and do a full conversion and rebuild.

In July last year I purchased a 96’ FZJ80 from a salvage auction, as can be seen in the below pic it had front left accident damage, all superficial panel damage, no structural damage.

Now the fun begins…the strip down. The front end was stripped off and engine and trans removed.

Damage was LHS inner and outer guards, radiator support panel, LHS headlight, Lower indicator panel and front left hand edge of bonnet, the bonnet can probably be panel beat straight.

I think it should fit the FZJ80 has a very long engine bay and the duramax engine is not very long at all the width might be an issue but I am sure it can be made to work.

It would be really badass when done.

My dad has a FZJ80 and I love it, with a duramax it would be out of this world cool

Still deciding but I will most probably go with the original Toyota diff in the rear with air locker and solid pinion spacer and a hybrid Toyota/patrol front diff. I'll use the GU centre with ARB air locker and Toyota side gears with the original axle tubes, hubs and brakes.
Rear diff should be strong enough with the solid pinion spacer and the front diff with GU centre will do the job on the front. This way the braking system remains original and balanced.

Now with the engine and trans removed it was time to remove the dash and strip the rest of the interior.

Once the dash was remove the ventilation fan, aircon evaporator and heater unit was removed.

The intrusion bar was then removed allowing easy removal of the wiring harness.

Here I have the complete engine and body harness in a box, some mods to be completed at a later date. :wink:

Now that the interior was stripped out I started scraping all of the original tar insulation off the floor and firewall. Instead of using the ‘chill and chip’ method I thought I would try the ‘heat and scrape’. I started with one 500w lamp but soon found that by using 2 x 500w lamps I could heat a larger area and get through the job a bit quicker.

MAN WHAT A JOB! Clean slate for application of new insulation at a later date.
