I'm asumeing the jeep in question is the one in your sig, 82 cj7? What do you want to do with it? Daily driver or on the rocks only?

You'll need a OD trans if you want to get on the highway and do more than 55 comfortably. D44 axles will do OK on the street but are marginal on the rocks with the 4BT, using a automatic will help. If you live in calif, getting it registered as a Diesel is easy.

your turn,

Steve

I put one in my Jeep. It is a 1997 TJ.



Here is the website where you can see it.

MY96Z, that is a great site. What kind of mileage do you get, and would you do it again ? Thanks, Ponz

Well right now I have just changed the axles, suspension and tires. I now have Dana 44 front and rear with 4. 10's the tires are nitto mudgrappler 35x14. 5r15. I am going to estimate that with A/C running and pure city driving (also about 3 hours of off-roading) I would estimate around 16 to 17 mpg. I will have better numbers tomorrow it will be time to fill it up again. .

I talked to the local cummins rep several years ago about putting a 4bt in my Landcruiser. He said all he knew of was some folks in Montana that had put them in jeeps. The upside was 40-45 mpg. The down side was getting the right gear ratios for highway use, mounting the engine level with out a monster body lift( something about the oil pan and the pumkin on the axle), and finding a complete assembly for a descent price. He recommended finding out the h. p. rating I wanted and then start looking for a delivery van that had everything in it. Just check on the price of an intercooler or a turbo from Cummins that wasn't included in the deal. Delivery trucks are great donors but all the ones that I have found in Northern NV are Chebby 350 engines. Portland has quite a few diesels but finding one with the HP rating you want might be a little harder.
