I have yet to lay eyes or hands on one, but the rumour is Aisin.

I was sure it was allison, but a quick search reveals it may have been both:

4bc2,4bd1, eagle1, 4bd1t or 4he1t are good motors you can also use 4d30,4d31,32 or 4d33t from a canter. all motors i mentioned can be mated to allison automatic trans.

early model automatic you need machine shop to do it for you they will make adapter plate to mate the ford bell housing in the isuzu/fuso flywheel housing. late model isuzu/fuso came w/aisin automatic trans. or a more durable allison.

KOTSE.COM > Isuzu : 4ba1 Vs C240
(it's a Phillipino website - half the posts are in english, half in Tagalog - sometimes in the same sentence!!!

For something different, I saw a site in the UK that was converting the 2.8TD 4M40 mitsubishi motors into RR's. They're a pretty good motor and something I'd be looking at, not sure how to marry up g/boxes though.

Cheers

I'd run the other way from that engine. In a challenger it gets worse fuel economy than a 100 series landcruiser.
But the Isuzu 4JB1T (2.8 turbo) would be an option.

Slap in a Deutz V8 air cooled diesel.
That way you don't have to worry about the radiator

Or if you want more grunt!

This lovely V12, only used by a little old lady to go to church on Sundays..

Just a tad too heavy, thanks anyway, Regards Frank.

I have the Isuzu 3.9T at the top of my list, I'm looking for an Auto box to suit, Regards Frank.

It looks like the Yank 700R4 type thing or the box that Isuzu used (either Aisin or Allison, not sure) is your only real option for a self-shifter.

A quick google search for this: Stanton 4x4

Not much info on fitment though. I was under the impression they were a strong motor with not much going wrong with them. I know of a few Pajero owners easily getting less than 10km/100 fuel use.

I know of two people who owned Challengers with that engine. They both got hit with very expensive fuel pump repairs at low km's. I thought coincidence until I mentioned it on a NZ 4wd website and the only regular there with that engine had the same story.

Fuel economy was around 8-9km/l, that's less than my rangie with the 4BD1T, despite weighing half a ton less and pushing less air.
