I'm getting ready to start a diesel swap into my low mileage near mint condition 89 Mazda B2600i 4x4. The motor has been ordered and should be here in 2-3 weeks.

Mitsubishi 4D56T 2.5L diesel with water cooled turbo...









To go into this...

Shouldn't you be using a boat instead of a truck?

That wouldn't be as much fun!
Nice swap! That video was pretty sweet! Looks like a fun truck.
everything is funnier without spark plugs
I've got a 1987 mazda b2600 4x4 I've been wanting to do a diesel swap on, sounds like it should bolt right up ? I have the mitsubishi 2.6L gasser with manuel tranny, any suggestions on where to find an engine ? Any other tips are appreciated !

P.S. sorry I'm new to the forum I posted before I found the 2nd and third pages, I see the links posted, thanks !

Yes, it will bolt up to the 87-88's.
Since the Ford Ranger (same thing) came with the 4D55t stock in the 1980s at the time did you give that engine a thought?

RPM guage

Hey cdalejef,
Love the thread. How did you get your rpm gauge working? Also did you install a glow plug controller or did you set something else up? You've got me sold on doing this to the little B2600i i picked up from sumerset, ky last week with a bad motor. The only thing I'm stuck on is what engine a low mileage jap import or a new crate engine.

Actually the Mazda didn't become a Ranger until 94. The 93 and early Mazda's are completely different. However the 4D55 is very similar to the 4D56 but and would fit but finding one that would need a complete rebuild would be very difficult. You could completely rebuild one but that would cost almost as much as a new crate 4D56.

Nice looking truck!
I used a Dakota Digital converter, it works great and is easy to install. I'm using a manual glow plug switch.
You've got to be careful on those import engines, there is almost always something wrong with them from what I've read.
I may have missed this part but what did u do for ecu also love the swap I plan to do this asap I have a 93 2600i with a tired motor but not sure about wiring and ecu stuff did u have to go standalone or ?

This is an indirect injection motor, no ECU. It only needs one 12v switched wire to run.
And What did u do for flywheel....... me n my brother are buying 2 of these as soon as we find em for decent prices 3k or anywhere near 3 k is nonsense for a truck that only sells for 2 k for gas maybe 3 k with a diesel
The engine came with a flywheel and clutch.
I'm looking to do this to my 90 b 2600i it just turned 200k miles still running strong but just wanna do something different any advice would be awesome thanks
What are you wanting to know?
If it is worth to swap to diesel or the 3.0 v6 mazda engine
It was totally worth it, I'd do it again.
Sounds like that's what I'm doing motors was just bought today
