I have a ford gp and thinking of modifing her cus she naked and all ready modified.
i would like to have: 4bt T18 dana20 on Fj40 axles or
4bt T18 LT95 (landrover/rangerover transfercase 3.3:1) onFJ40 axles
any ideas on axles- had an ofer of dana 60 front /80 back but was told they would be to big- dana 80 is 11/5 inch ring and axles rated for 10,000 ft/lbs of torque not bad at least they wont break with 33/35 tyers.
cuase of the 4bt rpm band of about 2300 rpm i might have to drop/raise the back ratio to 3.5 of lower- no lower then 3.00
if you can think of a ratio between on Fj40/dana axles love to here it.
by the way the 4bt is:
4 cylnder-like the dodge motor minus 2 cylnders
296-350 ft/lbs of torque @ 1700 rpm 90% avalibly at idle!
350,00 miles/560,000 garented before overhual from factory or 3500 hrs @ 50% load
$4500 with turbo 400( too long for jeep) will sell or give to jeeper!
not wanting to mod jeep too mutch as have the FJ40/45 axles in it
cuase it is cummins engine all dodge ford jeep amc gmc chev and ih bellhouseing work anf fit
