Easy, talk to your engineer as to what exactly he requires and what you need to do to create a roadworthy build.
If it were me and I had the coin it would be a 45/47 body on an 80 series chassis powered by a 200 series 1VD. Alternatively stick with the 40 series chassis, run 70 series axles and...
7.5k won't get you much of a 1HDFTE seeing they are now pulling 15-16k for everything you need for a conversion before you even swing a spanner. The 2.8 is not supported here and not worth the trouble. Besides the Aussie dollar is terrible against the USD so costs are excessive.
If you want a...
If it must be petrol what about the 1FZ?
Up to 240 ponies in the later models.
But as John said don't get hooked up on power. Personally I think a modern diesel is a much better platform but all depends on what you want from your vehicle.
If you want stupid power just put a 2JZ in it 😄
What's your budget?
What do you want from the vehicle?
Have a look at either a 1HD-FTE.
Smack on 200hp and one of the best diesel swaps you could do.
Or the 1KD-FTV with an easy 230hp on a simple ECU tune. This being my first choice.
I don't know the actual manufacturer, they are all Caterpillar branded.
Running a 40L fridge, some LED lighting, radio and USB charging of phones etc I can get nearly a weeks worth of power out of it. I also use a Cat 1000CCA start battery but they do many different models. You don't have to go...
Lithium will be horrifically expensive for a decent size battery. I recommend the Caterpillar AGM batteries. Along with their lead acid batteries they are decently priced for their performance. Have one as a secondary battery that's nearly 200Ah and been going strong for years. Being charged by...
Any Aussies here interested in a conversion kit to swap the 1KD-FTV common rail diesel engine into the 40 series chassis?
Although still under construction check this link out and maybe send an inquiry.

This is from a 2002 model vehicle.
As purchased through written off vehicle auction no service history is available. Engine was successfully test run in vehicle prior to removal with no known problems. Vehicle had only rear end damage so all front end components are in serviceable condition...
