1987 Mazda B2600 B 2600i from North America - Comments

No major problems since I did the diesel conversion, just a front cover oil leak and a power steering hose leak.

Bought pickup for $950.00 off Ebay with a bad 2600 engine, after looking it over looks like previous owner ran her out of oil (balance shafts were scored). I replaced the timing chain and guides to check condition of engine. Once I fired her up I relized it was better to replace then rebuild, too many valve train and rod noises and injection had been replaced with an after market carb.

Found an 83' Mitsubishi Turbo diesel pickup locally for about $1000, pulled and rebuilt it. First generation Mazda 4x4 used Mitsubishi motors, my 2.3 diesel bolted right to the bell housing and motor mounts with no alterations needed. Other then a little rewiring, the swap went very smoothly. Now getting 25 to 30 mpg! Future plans are to add an extra tank, fuel solenoid and some plumbing work, so I can burn used vegatable oil. Can you say Free Fuel !!

I encourage anyone interested in a Diesel powered Mazda to give this a try.

Thanks,

Dan

Are you refuring to the b2600i motor? I like the diesel option!

Yes, I am referring to the 1988 B2600i engine. Diesel I used is a 1983 4D55 Mitsubishi Turbo Diesel. After 10,000 miles, minor oil leak is only problem. Injectors might need to be rebuilt, rough idle when cold. I can be reached at toolman84@juno.com. Dan.

Is the 1988 B2600i engine he same as the 1990? I.E. would the 1983 Mitsubishi diesel fit the trans housing?? My 1990 has got a bad head that has already been repaired once and I would reallly like to convert to diesel instead of fixing it again. The rest of the vehicle is in excellent shape with only 140K miles on it.

The 1989 and later trucks used a Mazda manufactured engine.

1988 and earlier used a Mitsubishi engine.

The rest of the truck, as far as I can tell is the same.

To put the diesel Mitsubishi engine in a 1989+ Mazda, you'll probably need the earlier bell housing (To attach the Mitsubishi engine to the Mazda transmission.) and you'll need the earlier engine mounts. To go diesel, you'll obviously need diesel fuel system components.

Not true. I have a 93 and it's a mitsubishi.
