Turbowned

Does anyone have a source of good information on the engine specifications on the Apollo? I know it uses a biturbo Audi 4.2 V8. That's about it... I'd love to know more about which engine block it uses, which heads/valvetrain, what type of fuel system, ignition system, turbochargers, etc. if for nothing else than to imagine how to build an 800bhp RS6.
So far, this is the most information I could glean, thanks to Wikipedia:
The Apollo uses a 4163 cc bi-turbo (https://en.wikipedia.org/wiki/Bi-turbo) intercooled (https://en.wikipedia.org/wiki/Intercooled) version of the Audi V8 engine (https://en.wikipedia.org/wiki/V8_engine).[8] (https://en.wikipedia.org/wiki/Gumpert_Apollo#cite_note-8) The 90° V8 has a closed-deck light metal crankcase with dry sump (https://en.wikipedia.org/wiki/Dry_sump) lubrication. The light metal cylinder heads have five valves per cylinder, four overhead camshafts, VarioCam (https://en.wikipedia.org/wiki/VarioCam) Direct variable valve timing on the intakes, and hydraulic valve clearance compensation. The double-flow exhaust system has four oxygen sensors (https://en.wikipedia.org/wiki/Oxygen_sensor) to monitor the gas mixture, and a 3-way catalytic converter (https://en.wikipedia.org/wiki/Catalytic_converter). Modern controls include an on-board diagnostic system, eight-coil electronic ignition (https://en.wikipedia.org/wiki/Electronic_ignition), sequential multipoint fuel injection (https://en.wikipedia.org/wiki/Fuel_injection), and an electronic (drive by wire (https://en.wikipedia.org/wiki/Drive_by_wire)) accelerator system.
There are 3 engine types available:
Base version - approximately 650 PS (478 kW; 641 bhp)
Sport version - approximately 700 PS (515 kW; 690 bhp)
Race version - approximately 800 PS (588 kW; 789 bhp)
