From looking around there are several places that name the boxed fendered 924 as a GTR but they're the same sites that say the '86 was a GTP which I know to be false after talking with Kelly Moss Racing and contacting people at Fabcar...
This is so confusing sometimes.

That 924CGTR is the rallye version. People get confused because they think the bodywork is different to the CGTR, but its exactly the same.

I respect if you don't wish to disclose the numbers, but can you tell us a bit more of the parts used?
Like a bit more info about the dry sump setup?
IMHO the intake runnes are too long but they might be designed for a restricted HP race class where you wish to maximize torque as a result of the rules.
How wild did you go in the head/drivetrain area? Maximum rpms?

its car #74, the canon car is 75:

note that #1 is the 924 CGTP 944 LM and #36 is a CGTR, both virtually identical in appearance so that could get confusing.
anyone speak german?

lastly:
The teams using the GTR quickly decided to develop their own bodywork. I'll be back later to document these better, and fill in some of the blanks of technical content. For now, I will mention that some of the major points were boxed rear fender quarters as seen on the 935's, and 1-piece noses. These cars also saw much service in the Trans Am series.

More info please!!!
Either way, more shots of the rear fenders please?!?!?!?!

THE 924 IN THE PIC AT THE TOP, is a 924gtr, the gtp looked the same except it had a prototype engine with 4 valve /cyl head. hence since not being a production engine was ran as a GTP. This engine later turned out to be the basis for the 944. All or most of the 924 pics yoiu have shown where all known as 924 GTR's, The U.S. GTR ( holbert ) had a different style front with the rear box flairs. The GTP is with the protoype engine .
The kelly Moss Car was known as a 944 GTR , the first one done by Holbert was raced in the T/A seiries and in IMSA in the GTO class..
The 924 gtr also raced in the T/A series not sure how many races it won but did start from pole position a few times before making way for the 944 gtr.
also the 1st pic of the 924 GTR , to my knowledge only the factory cars had that front , The other styles where entered by privateers , with most of the body work supplied from the US by Holbert racing , the most famous one being the BF goodrich car , that was prepared and done here in the states .

Boost shaped 2 dim vs TPS/RPM , modified head , cam etc.. large Intercooler.
I 'm not one for one off custom turbos , unless they have been tried and tested , but i must say this one made a lot @ 1bar , well at least more than i have ever seen at 1 bar on these engines before.

Did you buy that turbo from a smart man that I know, Wayne?
