Thanks, yes I'm getting a lot of advice from Justin Cooper here in Tassie, he's the guru down here.Just a word of warning on the turbo kit, be happy with around 400nm of torque and the driveline will function as it should. Start cranking up the turbo for more torque and the CV's and gearbox will turn into consumable items. So you will still be as slow as the 76 you just sold. But the Perntie will ride better than the 76.
Having driven the Perentie off road, they are a pretty capable 4wd. The 3.9 Isuzu motor is easily equal to the 1HZ. Probably has a slightly better low down torque curve than the 1HZ due to the larger volume in each cylinder. Good luck. Keep posting the build, it will be very interesting to see how you fit this out.
The ride is good, the difference is you don't get the side to side movement in the cab like you do in the 76, which I think is why we were adjusting the steering wheel so much to keep the car straight.
