Ben, the tank is mounted under the passenger side just rear of the passenger front door, has approx. 23 ltr of useable gas, you can definitely feel the difference when it is on in relation to the power. I haven't had it dynoed with the gas on the chev but it used to give me an additional 9 kw at the wheels when I had the 2.8 installed. With the 120 % increase in the price of gas I only run gas every couple of tanks to try to clean out the system and reduce carbon build up. If gas was still cheap I would recommend the conversion but not any more. As for fuel economy I didn't gain that much in dollar value as opposed to power, if you turn it off at 100, you physically feel the car slow down.

G'day Ian,
I had just discussed this with Ben. I just got told by a fitter on site who had installed gas on his 6.5L and he said there was a 35% increase in power with no down side. He said the simple reason was that gas loves high compression.
The only reason I am not so keen to do it, as for Ben, is the loss of room for camping gear.

Always good to hear that, although until I dyno mine I think a 35 % increase is a bit high but good if it's true.

Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

Sorry RLI, until that got bumped up by ET, I had missed that one.
Yes, cost as per above. I am told however that if I want a 4L85E box put in, that it is a ten grand job! That put me right off...

Holy Cow, that sounds a tad high to me... I was told it was a an easy peasy swap out. I'll be a tad pissed off it isn't.
A crate 4L80 (IE new) with the higher rated TC was $5,000
A prof reco 4L80 manual shift was $3,000
A prof reco 4L80 and valve body with a compushift was under $5,000
The box bolts straight up to the Chev and the adapter for the Patrol transfer case to 4L80 is under $1200
Supposedly the Chev/4L80/adapter length is the same as factory engine/gearbox so the cross member/drive shafts don't need to be worked
I was going for a reco sometime sooner rather than later but if it's 10 grand it will be later thats for sure

Ten grand for install of a 4L85E at Gryphon Engineering here in Cairns, I just double checked. Gryphon work with/for Brunswick, so I'd guess it would be same price over that side of Aus.
I don't know whether it would be worth getting the 4L85 over the 4L80 or not, nor what the price difference is.
I do however have access to a mate with a hoist and mechanical ability, so if a reco gearbox was not a big job, then that is what I will consider doing. I have been very close to wanting to install a low range reduction gear at the moment as well. However I could save on that and put it towards an Auto.
