Info, is it worth the expense of converting the 94nj on gas. Also what can i do to reduce the revs when cruising on a 100 km hr 3000rpm to 2000-2500rpm

Personally , I wouldn't put a V6 onto Gas. Known to have head and head gasket problems.

What can you do to reduce revs. Change Diff ratios. Problem is , the V6's like a few Revs on Board. They work best between 2800-3500. I think you would run out of puff to much gearing down that far.

Hi Dyno,

A friend of mine looked at doing the same as you to his V6 Paj and was advised by the gas fitter not to covert it to gas as stated in previous post due to reliability issues. Ring a few reputable gas installers and see what response you get .

Have heard also not to run the pajero V6 on gas.

I have the same problem with revs.
Stock GLX with diesel and it doesn't like the revs at 100 either, most probably more than your V6.

You can get 4.6 diffs from an NL instead of the 4.875 in the NH. 5% higher.

Ended up going for 235/85 16s instead of the 235/75 15s. 10% difference and speedo is only out about 3%. So it does 2650 rpm at 100, or 95 indicated on the speedo. 730 dia to 805 dia, so38mm more clearance under the rear diff and front sump guard.
Reckon it only saves about 0.5l/100k. But top speed has gone from 145 to 155km/h indicated :-).

Oh, forgot to mention, 10% higher gearing also means 10% less power, so it is more of a slug of the line. And I wouldn't want to go much higher because you need to slip the clutch a little more on a hill start already. Overtaking at 100kmh also takes a couple of seconds more. And low first is not quite as low any more.

So if you are willing to accept that, for a 10% gain, go the tyres. A 20% gain in gearing would definitely need a lower first gear, but 4th may be more useful for overtaking. And the speedo would need recalibrating. Not sure how you would do the change in gearing though. An overdrive is what we need, but I don't know of any one that makes one for a pajero. Used to be made for the land rover, and there is one for the landcruiser, but it takes a lot of miles to save the $3000.00 in fuel.
Ideally we need a 6 speed box. Havn't found anything that would easily work or swap in.
