Titanium Torque Converter
The brown looking titanium pieces are titanium with a coating and the green coated piece is the magnesium transmission adapter; the other pieces (including the springs) are all made of titanium. Original weight of torque converter was more than 15.4 kg, now with the aluminum pieces not pictured, it is less than 6.3 kg -- and the adaptor piece saves more.
Not from a CGT, a GT2RS or even a 918 but a Porsche with a better power to weight ratio than any of them - a particular 964.

It seems the next logical step is to redesign the convertor to incorporate a lock-up.
As for power to weight, you're suggesting your 964 is over 400hp or close to 2000lb? I've seen you've done a lot to lighten the car, but I don't recall what you've done in the engine compartment, so that would be interesting to read about, too.

I've followed this project for years and it was and is an inspiration for me to lighten the GT3.
If memory serves me right the car is at 440HP and 440 Nm of torque and 1000kg.

I still have a "one of these days" project for 993 RSR clone ...
Okay -- enough thread-jacking from me ... : )

About the 9m engine "upgrades" when I had the 993 It was on my daily agenda to drool over them.

Indeed, we are at 2000 lbs (approximately 909 kg) and, yes, on a Porsche engine dyno, in excess of 440 HP and 440 Nm of torque - normally aspirated. As to the parts, none are 9M or any other tuner.
P.S. As to engine management, we use Bosch.
P.P.S. Maximum power is achieved below 7000 rpm.

Robert,
Impressive work as usual! Are you getting close to fire up the complete car?
One reflextion: As Porsche now is using the PDK gearbox and not wanting ( at least official ) to use it in the GT cars due to its weight penalty, wouldnt it be interesting to use your material expertise to make a "GT-version" of this gearbox and to reduce a massive amount of its weight? Think of a 991 or 998 GT2 model ( whatever they will call it ) with the new Turbo engine and this "GT-version" of the PDK gearbox. That would be of interest for quite a few buyers over the years and represent a healthy volume.
What do you think?
