Here's one of my favorite parts of the car - the fan shroud, which appears to be manufactured out of carbon-kevlar. You can see the kevlar grain pattern here in the red paint.

These are two "cycle valves" used by the turbocharging system to spool up and swap. One of the valves controls the opening and closing of the wastegate, and the other valve controls the crossover valve which sends charged air back and forth between the turbochargers. When the system is malfunctioning, the valves default to a maximum charge pressure of 1.5 bar.

Photos of the back of the manifold. Those aluminum tubes in the rear come from the intercoolers and transport the compressed air from the turbochargers.

Charged air tube from the intercooler, and some type of radiator tank. There's another tank on the opposite side.

The turbo system cycle valves, with the power steering reservoir in the background (I think that's for the power steering). Another water tank in the background too (on the right side of the car).

View of the whole engine bay with the air cleaner partially disconnected and pushed off to the side.

It's best to use a moving blanket to cover the important parts of the engine, so that you don't scratch anything or drop tools in there.

Here is the area where the pressure sensor goes. It's very crowded in there...
