Thanks for the comments guys, stay tuned 
Mid / late-week treat:
Stripping down the wiring harness is one of the key areas where a lot of weight was saved on this particular car, and some pics attest to that process. I cannot stress enough how time consuming and tedious a process this is, however the benefits you will reap are a lightened wiring loom, a better understanding of the necessary wiring in a 964, and greater control over what each wire is doing. If you are doing a lightweight project this is definitely one of the areas of finer detail, and one that will go largely un-noticed, but it is worth it!
Your typical 964 wiring harness... Don't forget that most of these harnesses are bulk manufactured and a lot of the wiring ends up unused and the plugs capped off...
Speaking of unused bits... this is what was stripped out, never to be put back again...
What remains in the car can be seen these two photos...from left...

Post the weight savings from the wiring project. Curious to know how much you eliminated. BTW, awesome project and love the color. Well done.

If I recall correctly, the loom started out at around 7-8 kg, and ended around 4-5kg... It's all about carving weight out of where you can to make it all add up. Other places that this can happen on the 964s is in areas such as...
- Electro-wing
- Rear wiper
- Metal brackets for rear seats, interior trim pieces, etc.
- Lightweight (OEM RS) door windows / plexiglass quarter-lights and rear window
- Motors and wiring for power wing mirrors
- Wiring for central locking
- Battery
- Sunroof

More "out with the old, in with the new" stuff... The airconditioning...
I will caveat this post by saying that Singapore is hot all year round. Hot and humid. By hot I mean 30-35°C (86-95°F), and by humid I mean >80% humidity... All. Year. Round. So leaving airconditioning out was not an option. What was an option was choosing what kind of airconditioning system to put in since this was a ground up rebuild.
The mechanic building my car happened to have a handy solution in the form of a custom, lightweight airconditioning system that is not only lighter than the OEM system, but also does a better job of cooling than puffing paltry whisps of cool-ish air out...
The original system weighs over 10kg, but I can pick the lightweight system up with one hand and very little effort... For a component that sits up as high as it does in the car, this is a worthwhile modification to make to manage weight and its impact on the center of gravity of the car.
Some photos:
The lightweight system runs off the car's stock wiring, OEM compressor, lines, etc. so there is not too much modification that needs to be made from that perspective. However, there is some work involved in putting together block off plates, mounting brackets, hoses to feed the vents, etc.
One nice thing is that you only get 2 control functions with this system, 1) temperature and 2) fan speed (3 speeds). You can see the control panel where the OEM one would normally reside:

I love this thread. A very ambitious project and incredible attention to detail. If I took my wiring loom apart my car would never work again! 10/10, please continue to keep us updated with your progress and pics.
Regards.
