2.3l diesel in a TJ

I have an 87 Ford Ranger with a 2.3 liter Mitisubishi Turbo diesel engine just over 100,000 miles. 87 hp 150flb torque
I read about the 4bt swaps,but will this 87 hp be enough to replace the 4.0?
will it be enough diffrence to be worth the effort?
Has anyone installed a Mitisu in a jeep before?
Mitisubishi used the 2.3 in there Jeeps,with gear drive transfercases

whats the benifet from a diesel swap in a daily driver besides the mpg,i get 19 now

sounds like a really cool idea, im not sure what the amount of work would be like, but definitely a cool swap. id say look at the weight of the ranger, and the weight of the jeep, along with difference in tire size. those seem like 2 big factors in whether its worth it. yes diesels will normally get better gas mileage, but the combination of a heavier vehicle and bigger tires could still become to much for the engine to handle and you could lose your economy advantage. but as ive said in other threads, dont do anything based on my opinion only. im sure there are plenty of other people here that have much more experience then i do

Keep the 4.0

I have been looking at buying a 85 Mitsu from a local guy. The head is cracked. In my search to find a replacement I have found that head cracking is common on the 2.3td. I had a 92YJ that I sold I put a 258 crank in it (1/2 inch longer stroke) than stock 4.0L. Ooodles of torque and super dependable. Only problem I ever had on the jeep in the 9 years I had it was the crank position sensor went out twice. From my understanding the 2.3L doesn't even get that good of mileage. I say keep the 4.0L. If you must have a Diesel I'd sell the Mitsu and get a VW or Mercedes diesel which are far more dependable.
