hey, im new here and looking for a little help... i really like Diesels and i have 2 ford rangers... one is a 93 and one is a 84... i would like to re do my 84 from ground up and put a 4 cyl diesel in to it... i saw some stuff on the Cummins 4BT but i wasnt sure how well it would work and what trans set ups it would use... i found a post on here from 05 on it and they said there was a set up where they used a TH350 GM trans in it? be like in a ups truck? I'm open to any diesel motor... i would like it to be a turbo and not super rare.. something some what cheap as well... any other tips or thoughts please chime in and say them...
There was a 2.3-liter turboDiesel factory option in the 1980s. If you can find the parts, this is the most straightforward swap as all the engineering & design has already been done for you.
A 4-cylinder, 4-stroke Diesel engine has a LOT of torque ripple - much more than a gas engine of the same net torque output. You can't casually swap a gas engine out and a Diesel engine in without re-engineering the clutch/flywheel/harmonic damper/torque converter/et al.
If you're going to go to the effort of swapping transmissions, why select a 3-speed non-lockup non-overdrive THM350 when 4-speed lockup overdrive transmissions exist?
With or without an overdrive, you'll need a different final drive ratio - you definitely don't want to be cruising at 3000 rev/min. You'll probably also want something beefier than the stock 7.5-inch axle.
A 4BT is heavy. You'll need to change the front springs, and then you'll need to change the front shocks.

- Hella headlights (highly recommended)
- DOT C-2 back end (also recommended)
- R-12 air conditioner converted to R-406a. Saved ozone and money
- 4.1:1 final drive converted to 3.4:1. Quieter, better mileage but it's a good thing I live in the flat Midwest.
- 9/22/2007, age 21: Still running well when reluctantly sent away for reincarnation, due to body & frame rust.
- Never did get around to converting it to french-fry oil, which is why I originally stumbled upon this site.

box the frame, figure out how to have more verical rise in your engine compartment.
Having driven approx 375,000 miles with two separate 4X4 Rangers (1986 1994), I am a real fan of these trucks.
This will be not much harder than an early Bronco swap or a Jeep swap.
Good candidates IF you use a 4 wheeler chassis.
BTW: 4bt cummins engines can be found with FORD, DODGE and Chebby running gear.

i know the diesel is alot more weight but i just like the... the ealry perkins are hard to find and harder to find one with a turbo on it... i thought about the VW's and a Marcidaes.. Sp.. but wasnt really sure how i would mount that motor on to a trans and t-case...
where are some good plasces to look for motors... i havnt had much time to look on here...
hey biblo have any pics of it? i want to see them both... i dont know what ranger to do it to... the 84 or the 93...
It seems to me that I read somewhere the the 4 banger cummins weighs about as much as a chev 350. so basically I would say do the front end like yours setting up to do a V8 swap. There are plenty of rangers out there with 302's
