The intake manifold is a large sheet metal plenum Descendents/Golden Eagle part that is modified by Papadakis racing to fit a different throttle body.
You can see the immaculate construction of the robotic, tig-welded Full Race exhaust manifold here. The manifold is made of thick wall schedule 40 stainless to resist cracking and to transfer as much heat as possible to the turbine. Stainless has half of the thermal conductivity as regular steel and the 0.120″ thick tubing really keeps the heat in.
Full race makes their own improved compressor bypass valve for the Borg Warner EFR turbos. The stock part is plastic and the hose bib tends to crack off and the housing warp and leak.
Borg Warner EFR turbos have a nice provision for a speed sensor in use here. The compressor housing also has provisions for tapping off pressure for boost control. The boost is controlled by an AEM Three Port boost control solenoid controlled by the AEM Infinity ECU.
The engine is dry sump lubricated. As drift cars advance with more grip and more G's, many teams are having to switch to dry sump lubrication to keep engines reliable. Papadakis Racing uses a Barnes 5 stage oil pump and a billet oil pan of their own design.
