Getting into the braking system of this build, we are using the StopTech brand, primarily because they are here in my SoCal backyard offering hands on design assistance AND their stuff flat out works !
These are the front 6 piston calipers (ours will be nickel plated) these work with 32mm thick x 380mm dia vented (floating) rotors. They already build the adapter brackets for these calipers based on the 911 3 1/2" front strut...so this made my prototype job easier !
Rear calipers are a bit trickier as I needed to start out with a cnc aluminum adapter (Rich Johnson Co.) that I've used many times while putting 986 Boxster calipers on 914 trailing arms. The adapter allows an almost 99% fit of the StopTech #ST40 4 piston caliper to the 914 rear arm. Just need to calculate the final fit using a few shim washers, then take the test-mule piece over to our machine shop to mill out the new L and R blocks.
Here is a mock up view of the ST40 held in place with 2 dowels (sharpie pens !) on my 914 trailing arm display (trade shows), NOTE; only using the solid rotor for a reference point. Final rotors are 32mm x 355mm (floating) vented StopTechs
Epic! Ben and I were having a conversation the other day about how much power this block might hold. I think you will be undriveable after 7-800chp, but how far will you push?

This engine will be so smooth and have so much low end torque that I think it will require a huge amount of discipline to keep things under control!
Self discipline behind the wheel will be the rule with the 2 drivers of this car. We have a bit of insurance on the block strength by adding the steel sleeved cylinders; and the lower end has a pretty beefy "Girdle style" design ...but limiting our outings to 21psi boost limit. Even Mark Donohue needed to chill in the Penske 917/30, as he liked to chirp the tires between 4th and 5th at 190 !
Custom built cart for hauling around the medium sized nitrogen tank; used for filling JRZ canisters and the race tires. Msds inc. carts always equipped with cup holders ¡

Provided your intake temps are in check I think you will make what you need well before 21psi due to your custom cams, port work, and increased displacement.
