1975 Mazda REPU - Build and Repair thread

[Reitrof]

Wow Chris, looks a full electric rebuild. Awesome work.

Wire tuck for the front end complete. I can check off turn signals, marker lights, head lights, high beams, horn, and electric fan. It's nice to see this old face again.

I'm also working on a panel to mount the ECU and O2 sensor module.

Awesome work Chris! I would have given up a long time ago, simply because I'd be tangled up in all of those wires.

 

[Reitrof]

Yes beautiful work Chris.

After months of waiting, I finally have an intake manifold.

Last night I started messing with the throttle linkage. Some assembly required.

 

[chuyler1]

Oh yeah, and I now have a place for that O2 sensor as well...

 

[bazooka joe]

Nice!!!! You do the weld too?

 

[chuyler1]

No, I farmed out all the welding.

 

[Reitrof]

I thought farms had wells??

Nice Chris, looks good. Don't sneeze or drop any of the linkage parts.

It is just the repu or is the RX7 getting one.

 

[chuyler1]

Just the REPU for now, but if this goes well, I may consider a similar setup on the RX7.

Making progress this week.

Rear lights and trailer hitch are all wires up now. Turn signals, hazards, brake lights, and reverse lights are all up and running.

O2 sensor, reverse switch on transmission and starter are all plugged in.

Coils are mounted and custom short spark plug wires connected.

I fabbed up a bracket to mount the vacuum line manifold to the back side of the throttle bodies using some angle aluminum from Home Depot.

Lui stopped by to help out with the engine wiring harness.

Meanwhile I snaked 8ga wire through the cabin to connect the alternator to the fuse box.

We need to figure out what size injectors fit this fuel rail and procure a few more fittings, then we should see this truck up and running in a week or two.

 

[chuyler1]

Swapped out the old fuel pump fora walbro unit. I will revisit this later with proper fittings but that will require removing the bed to access the rest of the lines.

 

[Reitrof]

Chris, just curious, do you keep the old parts?

 

[chuyler1]

Yes, I haven't thrown anything out yet. Although I did sell the wiring harness to someone in need.

 

[chuyler1]

Painted vacuum hard lines and installed new orange mishimoto vacuum hose. Also competed the engine harness bulkhead connector.

 

[chuyler1]

Coolant ports blocked off, OMP blocked off (going to pre-mix), intake finally bolted in place, and vacuum lines sorted.

Working on the fuel system.
