All sounds very familiar for me...
Dry sump system
Stroked Step 3 RB28
Dual fuel rails and 12 injectors
Direct port nitrous system (Dry)
Big Single Hybrid Turbo
Drive-By-Wire throttle control
Holinger GTR6 Sequential Gearbox with custom ratios
Shiftec Pneumatic Air Shift - with paddles for clutchless up and down shifts
MoTeC M800 ECU with all options
MoTeC C127 Dash (playing with the software now making my own custom screens)
Plus a whole lot more!
The biggest issue you will have IMHO is finding someone you can trust to set it all up for you but I wish you good luck if you decide to build one
