[trooper Tdiesel]

there are some 4.30 gears that the 3sp autos had, other then that its all 4.62/5.12~ or MUCH higher....

i found a chart of gearing for those things, its long gone and deep but it is on this site...some where..

a 2wd 2 door is about 2,330lb stock 4 doors are around 2,600.

other then the VW idea there's one other set up i can think of..
51hp 1.8L SOHC 4FB1 out of a Isuzu I-mark, being RWD it would be a fairly simpal install.

the engine is about 380lbs and the trans is around 80lbs other then the VW diesel engines with an alloy head, its one of the lightest all cast iron old school diesels out there. set up for highway use.
the 2.2L c223 that the pups have is around 450lbs and uses the same MSG RWD trans just the starter is in a different spot. there meant more as a lugging engine in a truck then a high revving car engine..

the I-mark was around 2,280lbs and the SUV being about 2,650 in a 2 door with the doesel + added aro drag. your looking at a auto that will feal like it's hitting a power wall at around 45/60mph clean up the aro and it would likly be ok tell around 60 going 70+ will be WOT or real close to it....


if your going to swap out the diff with another one, id say 3.73/4.10 for larger tires such as 215/75/15 or 225/235s
smaller you could try a 3.55 diff but with larger tires you will end up driving it as a 4sp....though in some cases it could help economy, as having your trans in direct drive and the diff making up the O\D it can make for a more efficient drive train..
