Our FIC injectors are at home, secured by the Hypertune fuel rail.
MKC got to work on the rest of the fuel system using stainless steel braided -8 lines and black AN fittings to match our trick PHR engine breather and power steering reservoir relocation kit we’ll be discussing shortly.
While this car’s previous fuel rail system used a -10 line to feed the fuel rail and a -8 for the return, MKC decided to feed both fuel rail ends with -8 lines and return the fuel with -6 pictured in the center here.
Taking a closer look at the Powerhouse Racing engine breather kit, you can see a little bit of its proprietary internal baffling. PHR wants its customers to know it isn’t simply an oil “catch can” but rather a true engine breathing system for high horsepower applications (although modestly modified Supras will benefit as well).
If you’re building a high-horsepower turbocharged car, consideration needs to be given to the potential crankcase pressure buildup. Since the stock PCV valve is only 7mm in diameter, it may not be enough. The -12 lines used by PHR triple the ventilation area, keeping the engine’s efficiency and, thus, horsepower, at an optimum level.
