1987 Mazda B2600 i from North America - Comments

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.

I have a 93, the engine is Mazda, 89-93 were B2600i, those trucks were imported from Japan and used the Mazda engine, the G6 fuel injected I4. The B2600 from 80?-88 was made in Canada by DSM: Diamond Star Motors, which is why it has the Mitsubishi G54B carb engine is found in early models of the B2600, the difference is the starter, the G6 is on the passenger (right) side, the G54B is on the drivers (left). Good luck, it is possible.

I have a 1991 ext cab 4x4 with a 4D55T turbo diesel, and I have a 1989 reg cab 4x4 with the 2.2 Perkins non-turbo diesel and I wouldn't have them any other way. :)

I have a 1993 Mazda B2600i and a 1988 B2600 (1988 is rusty as hell). I plan on using the tranny and mounts from the 88 and putting them into the 93 with a 4D56T diesel. Do I have to cut the motor mounts off the 1988 frame? Or do I just need the mounts from the old gas engine? And is the tranny mount still in the same place?

Thanks.

OK, First you can use any of the two trannys as long as they are 5 speeds, the motor will only bolt up to the 88 bell housing, and other than that the trannys are identical. The motor mount you can use are the ones that are on the 2.6 from the 88 that will need a little modification of the angle of the mounts (it's pretty easy); can do it by eye once the motor is suspended in the engine compartment.

Next is the oil pan; the 88 2.6 oil pan will bolt right onto the 4d55t, but I have not seen a 4d56t close up yet, so I don't know if that is interchangeable. If you can use the oil pan of the 88 2.6, you will need to do a little modification to the oil pickup tube.

If you have any other questions, just post them as I will be checking this thread often.

Good Luck.

Hey,

Thanks for the info, as far as the mounts go, I would assume that if I cut the mounts off the 88 frame, that I would just have to weld them in the same place and in the same angle as I cut them off the 1993?

Thanks Again.

Also, will I need a different radiator? Someone had mentioned having more cooling power? My Land Rover diesel runs really cool, so I was wondering if I would be OK with the stock 2600 rad?

Yes with the first question. Now with that radiator, with my 4d55t I used the b2600 radiator out of a pre 89 b2600, because the inlet and outlet was on the right side as to fit radiator hoses better. The Perkins hose configuration makes the post 89 b2600i radiator the one to use if you were swapping a Perkins. The 88 radiator will be more than sufficient to cool your 4d56, and the hoses will be on the right side for you. I hope that helps, thanks for the interest and good luck!

The 4d56t that I got has a dual mass flywheel, do you think the flywheel from the old Mitsubishi gas motor would work?

I heard dual mass flywheels are a PIA and that you can convert to single mass. tomaco1 at hotmail dot com

Thanks.

Hi, I am thinking of dropping a Chevy 350 into my 1987 B2600. So anybody think there would be any problems doing that? Any suggestions? It won't be no problem if I have to go with a turbo 350, will it? Maybe I'm just dumb, but I thought it would be pretty cool.

To the guy that pulled the motor from the Mazda pick up, I am looking for some parts off that motor. If you still have it, please contact me at 856-963-2002, ask for Frank. Thanks.

I am trying to put a 2.2 liter diesel from a 1984 Mazda B2200 in a 1987 Mazda B2600. Any suggestions?

Will the Mitsu diesel fit the 1987 B2200?

I am sold on the idea of a Perkins 2.2 diesel in an 88 B2600. However, I would prefer a FWD. Does the bell housing of the FWD models bolt right up the Perkins engine, like it does with the RWD models?

Also, how much would it reduce the fuel mileage from the RWD to the FWD?

Thanks.

For the b2200:

If you have a 5 speed, you will need a bell housing for the B2600, and the steering cross member in a 2wd is different, so you may have issues there for oil pan clearance. The diesel has radiator hoses at the top right and lower left.

I'm in the process of dropping in the Perkins to my 87 b2600. I've read the bell housing are interchangeable. Is this true? What else will need to be done for this to work?

I have an 83 Mazda 2209 diesel. Will it fit in my 86 2600?

I have a 1983 Mitsubishi 4d55 diesel. I want to put it in a 1991 B-2600. Will it bolt up to the tranny?

Where can I buy a 4d55t motor?

Yes.
