Well done, nice to see another RB26 240Z.
Did you run into any ignition issues with the Autronic SM4? I used to run an SM2 with mine but have now sold it on. It used to heat up the ignitor pack (the square thing on top of the spark plug cover) really fast and cause missfire. I was told that it was due to the fact that they batch fire the rather then run sequential for the ignition.
Not sure if that caused the problem or if it was wired up wrongly.
I have run out of excuses to not finish mine (just needs another ecu and minor cosmetics) so I should get onto it shortly
Maybe you can make some videos of the car so we can all get warm and fuzzy over it?!
