kerb weight of an Amarok is 1000kg (2200lb) less than an 80series.
quick search shows power and torque of the 2.0 amarok as around 160hp/300ft/lb (depending on model year)
Please don't change the spark plugs on my dieselsounds like with some of theses modern diesels, you practically need to be a rocket surgeon just to change the spark plugs!
Jokes aside, these new ones are stupid easy to work on. The manufacturer specific diagnostic programs (available to the public btw) make it a breeze. Down on power? Computer tells you why. Rough idle? Computer tells you why. And so on.
That's a much more modern power to weight ratio. A ratio that the 80 never even came close to achieving.
Fwiw, the 80 came stock with 17 lbs per ft lb of torque. My proposed solution would bring it down to 11.8 lbs per ft lb.
Also, my google shows the Amarok at 4129 lbs to the fzj80's 4,751 lbs. My suggestion would actually give a better power to weight ratio.
Yeah, it is acually interesting to see some numbers like that.
FWIW I dont think 4750lbs for an 80 is correct, but not certain. my HZJ105 is approx 2800kg kerb weight which is approx 6700lb

What potential is there to increase output of one of the VW engines?
It would be interesting to compare the power to weight ratio of an 80 with a tuned up 1hd-t or 1hd-fte

Turbo, nozzles, and tune will get you 400 ft lbs. The 4 cyl VW can't get keep up with a modded FT/FTE tho, powerwise.
My HDJ81 with factory winch, 3 people in the car, and tools, weighed in at 5,581. I'd imagine 4,800 is at the lighter side of reasonable for a FZJ80 without driver.

QUOTE="mudgudgeon, post: 10754329, member: 30057"]I can't imagine a 2.0l, 4cyl engine being particularly impressive in a 2.5+ tonne vehicle. I guess torque is torque, but how highly strung and how heavily loaded is a 2.0 going to be in a cruiser?
then what do you use for transmission? the donor vehicles trans? Adapters for transfer case? is a transmission from a 1800kg vehicle going to cope lugging a cruisers 2800kg fat ass around?
Or do you use a cruiser trans, and reinvent the wheel making adapters to the engine?
what would you need to do with final drive gearing?
plus, it would look ridiculous in the engine bay of a cruiser, you'd fit two of them in there

Don't be too quick to mock a small diesel engine. If you look around on google, you'll find the story of a guy who put a 2.0 BMW diesel in a C303 and that thing was bonkers. I've also seen stupid fast diesel Audi wagons, I saw one at Pamona running 11s.

I'm interested in the V6 TDI. You'll have to forgive me, I haven't done a lot of research on these. From a cursory view, it seems like 300hp and 500ftlbs is very doable, maybe with just a tune and an intercooler? I don't know what search terms to use to find what I'm looking for. You sound like you've really looked into it, could you point me in a direction? I really like the idea of the V6TDI, they are very quiet compared to the more industrial options and smooth.
I know the small diesels can be impressive. just more the concept of a 2.0 hauling a cruiser around just seems improbable. in a lighter vehicle, sure. I'm not convinced it stacks up in a cruiser.- Thread starter

That would be the best part of any wheeling trip.
"What do you have in that thing?"
"A turbo diesel"
"Can I see it?"
"Sure"
And then stand back and watch them try to figure out how that tiny engine is hauling an 80 series around.

would definitely be outside the V8, Chev V8 diesel, cummins, isuzu engine conversion box 
I mean power is power.
Now, for the V6, I would probably just get a wrecked Touareg at auction. You're going to need harness, ecu, pedal, and a few other bits.
Fastforward Automotive in Canada can make you a complete plug and play harness, which will cut your swap time in half. You'll also want to delete the immobilized harness, and get a tune at the same time.
I don't know of any adapter plates, but those are easy enough to have made for you. Rest is just simple motor mounts and cooling systems.
For transmission, I would use the amazing 5 speed auto out of the late model 100 series.

Stage 2 tune for V6 puts out 340/530 hp/tq. That's with no other required mods... insane lol

I'll have to keep my ear to the ground for a wrecked one. I dunno how often they come up for auction. I have two bone yards around here, one of which, if I call and give the list of stuff that I'm looking for, they can get it all together for me at a reasonable price. When I put an LS in my 914, they saved me a lot of money and time.
As for the trans, the A440 proves to be really tough. I've seen some crazy 62s and 80s with built V8s and 40s and the A440 stands up to it.

All of that from a simple tune?! Those numbers are just about perfect for what I'm planning to use it for. It'll do all the wheeling I'll ask it to do, it'll tow my boat, and get good milage to boot. I'm so glad you spoke up. Now its down to finding the hard parts.
The 2.0 in an FJ40 would be amazing too. That might be a future project
Keep us posted. Also, set up reminders on Copart and IAAI to see when Touaregs come through auction.

Power figures are power figures, but you also need to think about where th power gets delivered in the rev range. A 2 litre amarok in my opinion is an absolute dog, especially towing, which I used to do with one quite frequently. That's in an amarok. Imagine in a heavy cruiser...
The V6, V8 and V10 are a totally different kettle of fish though. We also had a 4.2 V8 TDI Touareg that we towed with and that thing was absolutely sweet.
However, we got the help of a local VW specialist because myself and another colleague were considering putting a 4.2 TDI in an amarok. Obviously, fitment wouldn't be an issue, but apparently the ECU is looking for signals from absolutely everything on the vehicle to enable it to run, even down to the door lock actuators and he said without those signals being received, it wouldn't run properly.
That's as far as we got, went and bought a Ram 2500 6.7 instead and love it, but considering further, MTM performance has a 4.2 in an Amarok, and I believe they use a stand alone ECU, but don't quote me on that. I wonder if the ECU could be flashed to not look for those inputs? It would certainly be a nice engine in a cruiser, but the ECU thing is something to consider.

the problem with flashing the OEM ECU is having the code cracked so you can write new code, not something too many mechanics can even contemplate without a lot of help.
