1984 626 2.0D Swap

Recommended Posts

How in the world I get myself into these projects.... SMH

I picked up an irwipi (it ran when I parked it), a 1984 Diesel 626 on Thursday.  I have a 1988 Mazda B2000 that needs a motor.  Perfect.  I'm going to swap them.  If anyone needs whats left of this 626, its on the Central Coast of CA.  

Side saddle to prop swap.  Ive gleaned some information from others that the clutch itself does not swap.  Its rumored that a 1990 Kia has the clutch I need.  Can anyone verify this?

Wiring Harness and ECM.  I painstakingly removed the harness. all the relays, fuse block and other necessary items.  I could not find the ECM.... i researched it and found that it was somewhere under the dash.  I was unable to find any other information.  I found a module, under the carpet, but it was very small and it said NGK spark plug company?????  It was bolted to a zinc plate so I thought SWEET, I found it.  I removed the plate and..... it was just a plate, there was no ECM attached to it.

The motor is out and turns.... I'll replace the timing belt and all the others before I fire it. 

I'll pull the vacuum pump for the brakes on the pickup.

The questions....

Did I simply over look the ECM somewhere??

Are the fuel lines and tank needing to be transplanted as well?

Thanks in advance.

I'll post pics later

Being 1984 and diesel there may not be an ecm as older diesels run by compression rather than spark timing unless its common rail (CDR/I). I don't know how much you know about diesels, so scan if you have a good idea already.

Timing is done the injection pump on the side of the engine, a disc spins inside the pump which allows or cuts fuel to the injectors depending on the cylinder. Diesels HATE air in the lines so sure to bleed/prime it of air, there will be some for sure with the engine out/apart.

Yes to diesel fuel pump. Tank and lines possibly as well. Being a B2000 you'll have and advantage of being able to route them in different ways rather than only one way like in the 626 it came from. Make sure the fuel lines are not too close to the exhaust - seen a few cars melt from that. Fabrication work possibly needed I don't think it will just bolt right in.

Clutch - you'll be using B2000 box, flywheel I'd imagine. A 225mm Mazda clutch should fit - B2000, S1 (maybe2) RX7 clutch is an upgrade over B2000 as is an RX7 gearbox. But being a diesel the B2000 one should hold up as long as its not a skid ute; sustained instant torque transfer will make it shatter.
