I'll order the mazdacomp stuff soon... but I believe GRM will provide the rest of the decals required for the event.

The RX8 is sitting in the driveway now (where it probably live for a while during the RX3 build) so I'm sure I'll already be on the "radar" as it is. Oh well....

On another note.... fixing the headers is proving to be more difficult then I expected. Each radius has multiple repairs, and the cracks are were its REALLY thin. I may have to cut out and replace the entire radius, or give a try at one big patch on each...

This thread is ice cold, but here are the cliff notes to try and catch you all up...

May 2013, brought the car back to the house to begin the next phase of the build which would involve swapping in an EFI 13B and the interior overhaul.

Here's a shot of the interior prior to the overhaul. Basically, everything that wasn't already removed, got taken out and everything got a bath.

Then some repainting would begin to match the exterior and give the car an overall fresh appearance.

While repainting commences, a new dash cover is also contstructed, this brings us up to about August 2013:

Also, during August 2013, we test fired the 13B donor car after it sat in MC's woods for the last several years. Fired right up basically.. easy win! We let the engine warm up, checked all vitals we could and pulled it out.

Brought the engine home and had it await the install:

After going through a few different clutches, we pulled the best disc and tossed it on. OEM flywheel and OEM clutch setup for now. Modified the front engine bracket and dropped it "right" in:

Fast forward to September 2013, attention was once again turned onto the interior to finish it up in order to setup the mounting idea and wiring setup for the ECU and new return fuel line, etc.

It started feeling like a car again:

I know Brian can appreciate this, but this is how many hours in the garage looked while working on this thing. We had to mix the previous harness setup and the new EFI harness setup to get it squared away:

Punched a hole in the firewall for the new harness and mounted the ECU:

By October 2013 the engine wiring was mostly completed for the purposes of test fires and idle time, but we needed to address cooling. The radiator was reused and a new 10" electric fan seems to be doing well of keeping it cool. The issue with this setup is it leaves no room for a traditional pull config, so for now, its a front mounted push fan:

Out back we needed to address the trunk paint and fuel system as we now needed a return system:
