Transplant underway

So - I have completely dropped the ball on the blog.  Lots of updates:

I finished most of the welding where I plan to anyway.





I wanted to include some additional heat dissipation, so I made my own heat shield spray.  I used a can of roofing elastomeric, mixed with ceramic beads that I got from a company in FL (NASA spin-off).  I used an undercoat gun from a previous project to apply it.  The results are pretty good, in terms of adhesion and look - however, it took like 2-days to completely dry.

I sprayed underneath the car, in the tranny tunnel and between the framerails.  I also applied it to the firewall inside and out, and the complete floor pan inside the car.  Under the hood, I masked off the area and only applied right behind the motor as I wasn't sure how the urethane paint would work with it - it seems to work pretty well - but the test will be with the heat.





As a backup - I installed some heat barrier padding and used aluminum tape to seal the seams.




I apparently forgot to take a picture of the engine bay empty and painted (thought I did), but anyway, I painted the engine bay black - I know, I know, I said I was painting it Blue, but I did not think I had the patients to change the car's color, given all that comes with it.  Then adding insult to injury in dealing with the govt and title issues, etc - just thought "A black roadster is pretty cool" - never owned a black car anyway...

The engine is mounted for good (I hope) and the wiring has been 90% completed, but still needs to be wrapped up and tucked away.  I sent my PCM off to be programmed (Missouri is the location - and I noticed somehow UPS routed it through Massachusetts? - how does that happen?).  I should have it back next week.  I had them delete VATS, Skip Shift and EVAP - provided the info for injectors, fuel rail, tire size, etc.

Emission compliance is the goal - but I may not make it happen.  All other functions should be operating to pass emissions, except this little jewel:
The Fuel level indicator logic that works in conjunction with EVAP.
I need to still work on the solution for the fuel level in the PCM - as it is part of the diagnostics, which may throw a DTC and prevent emissions from passing.  The problem is the PCM measures the resistance on the fuel gauge and if a change has not occurred with 79 miles of driving, the DTC occurs and the PCM defaults to empty.  So I can't just use a resistor on the signal, nor can I use the Miata fuel sending unit - as its signal is reversed/different resistance than the LS1.  Hopefully I'll find an electrical genius to help me figure out this conundrum...



Yes - it is a rat's nest right now - as I said, lots of work still in the details.

New radiator with fans mounted


So now I am working on mounting the frame rails to the car, after that, install the fuel line - and continue waiting on parts to arrive.  I decided on replacing the Koni shocks with the Vmaxx Extreme Track Pack coilovers from FlyinMiata - and will likely use the FM LBBK brake kit to finish it off.  I do have a full set of urethane bushings to install, once the coilovers arrive, I can tackle the suspension.

  1. I think it's about time you take a couple weeks off so you don't start yours before I start mine!! Great work thanks for posting!!

  2. Fun to look at these shots because with a black car it looks so much like home!

    I think your dipstick is turned around. The bend right at the header goes forward rather than rearword on mine putting the yellow handle right by the oil fill.

    With your wireing harness over the top like that will the trans plugs reach? Mine wouldn't...

    Good to see the progress!!

  3. What rad did you use? I have a koyo rad that looks just like yours.. but the Outlet on the bottom comes out on the drivers side of the car, thats a lot of routing..

  4. I used a Mishimoto that was a bigger replacement for the Miata - I used the factory mounts (moved), but it all fit like it was supposed to.
