You can see how low in the chassis the engine can be mounted with the dry sump system.
The heat exchanger at the front of the car is for the coolant and the second one (the one you can see with PWR and C&R on it) is for the oil. I think that’s a massive inline oil filter mounted down low with an oil pressure sensor also installed. Large radius 90-degree fittings are used to minimize pressure drop. Gold foil on the bottom of the airbox is used to reduce the radiant heat transfer of the hot heat exchangers from warming up the air going into the engine.
The headers are long tube tri-Y design. It is definitely a tight fit between the frame rails.
The driver side header snakes around the back side of the engine. Hence all the gold foil on the firewall to reflect the heat. Look at the upper frame rail and you’ll notice a notch in them. That notch is from the historical design of the frame when a larger engine was fitted and the notch was required for clearance. The notch isn’t required for the current generation of engines, but I guess the frame builders didn’t get the memo.
Solid electrical signal connections are required through the bulkhead to ensure reliability.
The passenger side headers snake tightly around the frame rails.
