I emailed Paul Gillis from the Australian Cobra Car Owners Club Register. Not only does he drive a V8 Soarer, he twin turboed a 1UZ-FE for his Cobra! Note the twin throttle body conversion, manual trans and custom computer. Not intercooled. Some good shots of the caps and rotors. Here's what he had to say:
I have attached a few pictures of the engine and build.
The car is still under development - money being the main restriction! When
funds are available I plan on fitting a fairly large bar & plate intercooler and
upgrade the turbos to a pair of Garret T28 ball bearing items. At the moment I am
running a pair of T25's which deliver great low down torque but tend to run out of
puff at around 5500 rpm. Chiptorque mapped the engine to run extremely fat to
overcome the possibility of detonation without intercooling although water/methanol
As a result there is huge potential for more gains. Currently the car is
pulling 220kw at the wheels with 520ft/lb of torque.
The car has won some reasonable awards recently for show & shine -
First 2001 Cobra Nationals, 1st overall, Best paint, 2nd engine bay at
Automania on the Downs, Best paint & 2nd overall Automania Cleveland, 1st & best paint
2002 Qld Cobra titles.
By the way, I drive a Lexus SC400 Limited for every day use - great car!

Here's a top supercharge installation:
Mohammed Chowdhurry (ClubLexus, GS400), pushed over 2 bar into a 1UZ with stock head gaskets, 700hp, 12s quarter mile, $60 000 US spent.
In US there is a twin turbo kit for the SC400. Don't know about price or availability:

I emailed MechTech, here's the reply - looks like a few people emailed them the same sort of time as me as this was addressed to 5 people:
Thank you for your inquiry. We have Twin Turbo charged (2) SC400's, a couple years back. (you can reference the turbo mag article on our web site). The systems worked great. We do not however tool or jig the system. It is custom 1-off install. The cost is approx: $14,500-$15,000. We are considering going into manufacturing so we can produce a kit. I estimate the Kit cost at about $8900-$9500 complete. Please call us for further details. 760-432-0555 Best Regards Jim McFarland
