87 b2000 2.0 carb conveson to fuel injection

hi bsceners, im goin to atemp to change my carb to efi cus i dont like carbs and it is giving me problems running think it needsrebuilt. if any ones done this for the 2.0 let me know if not ill do a wright up as i do it, ive seen people do it to the 2.2 2.4 . i hear the 1985 mazda 626 has same motor but efi so thats where ill start , and swap pumps from a newer excab mazda bseries efi.

any suggestions or help leave it here thanks

(sorry if this ant in the right forum i am not on here much)

I think alot of people used the kia sportage motor, it has the same block FE3. So, that should give you another option to check on, plus a much newer motor.

I was just looking into this because I was given all the fuel injection parts but wasnt sure if it is possible. Info is needed before I start. lol

someone help the brothers out!

The conversion is possible to do. I have done it before but I had to build my own ECU. I used a megasquirt I setup with the narrow band o2 sensor, and it got the job done but was a PITA to tune. There is another member over on Mazdatruckin that does this swap as a hobby for all of his trucks.

The ECU can be wired into the stock harness but it you have to map out the correct wires. Also the car ECU is going to be tuned for a car and not a truck so it might not get you what you want.

You'll also need to get the valve cover and the distributor from the 626 if you plan to run the ECU for that vehicle. The valve cover is because the port is lower than the valve cover stock for the pickup, and there is a partition from the factory in place on the 626 VC. I used the stock pickup VC and I had to cut a notch in it and use JB weld to make a flat surface.

There is one more bracket that you are going to have to cut off of the stock intake manifold from the 626 because it will hit the thermostat housing of the B series otherwise. It's easy with a hack saw. And you'll need to make a partition for the coolant temp sensor because on the B series it's in the manifold and on the 626 it's on the head (could be the thermo housing, I don't remember.)

Sweet ill try soon I hope money :,( lol. Could I just say get the motor computer and sensors from a 626 and bolt most it in to the stock tranny and splice wiring in

you will have firewall clearances with a completely stock 12v 626 setup. other than that, yes.

using the 2.0 8v efi setup from the 626 is going to make computer splicing a lot more difficult. It is possible but the 2.0 EFI system was more complex.

well i was plaining on useing the computer for the motor i get and splice it to the gauges.. that should work right? i just want something fuel injected to bolt to my stock tranny cus i dont like crab...any ideals

There is a user over on Mazdatruckin named MadLowMazda that does this as a hobby. On one of his build threads he has a complete list as to what would be needed for such. It is completely possible to splice the wires from the 626 into the B2600. It is also possible to pull the entire motor out from a Kia Sportage (95-02) and to use the accessories for the Kia and mounts/tranny for the mazda. Silentdawn over on MT did this in his as well. The Kia motor is a dual cam version of the FE3 and our trannies bolt onto it the same. Our accessories do as well but the exhaust manifold interferes with Mazda accessories.

thanks ill look in that
