Yep, my car. 1 of 5 (I think) kits from 928 Specialists. DR's been having some health issues, so I don't think they're shipping right now. Base price is listed at $7,500, but I think you'd be looking at closer to $8k or maybe even $9k after all is said and done.

Yes, this is the Andy Keel ver 1.01 kit. That means that it is intercooled and that there were a few other major parts with the kit but lots of engineering left to the installer. It is the Auto-rotor 2.2 liter twin-screw. There is much more than seen in the pictures such as the $145.00 ProVent Oil Separator, single-fan shroud and electric fan, induction boots, intercooler rad and fluid pump, RRFPR (in case you want to go that way), 6psi and 8psi supercharger-nose pulleys, and some more smaller bits like the lower pulley and bolt and some belts.
It didn't include the throttle body, used the OEM S4 throttle quadrant. For the '87 cars it needed 25# injectors but later cars had them, and it required some engineering imagination.
It was supposed to put down 450 hp or there-abouts. I am running the Carl's X-pipe as well.
The power steering pump is OEM as is it's location. The spacer is all that was needed the get it onto the one ribbed belt. The idler between the PS pump and the alternator is my design. This makes the accessory drive system simpler than it was stock. The A/C drive is unaltered.

It looks like Brian is selling off a good kit here, with extras, I wish I had the cash
Also a quick question,.... what is the max boost that you can put into a stock 10 to 1 engine.

Heck while we're at it, why not a Weiand 6-71 or a Keith Black 8-71 twin screw? I know of at least one 928 that has a 6-71 poking out of its hood... of course, it's attached to a Chevy motor.
Why not you ask?
There are only a few SC designs that can fit under the factory hood and still have to have many parts designed and produced to make it work on a 928 motor. VERY EXPENSIVE.

How long do you want it to last? 
I'm running 9.5psi, Murf's kit will go up to 15psi with no issues. As long as you can control detonation, you should be able to go up quite a bit higher on stock internals. But once you start knocking... watch out!
