Vivid nimmt beim (sehr) leistungsgesteigerten WRX eine Toyota Supra Fuel Pump & Fuel Pressure Regulator sowie STI 550cc injectors.
Desweiteren gibt es das sog. Perrin Fuel Rail Kit für $429.99
The EJ20 Subaru engine is infamous for leaning out CYL. # 3. The stock fuel rails and lines allow more fuel and pressure to be distributed to the other cylinders. When WRX owners begin upgrading the engine and adding more boost and more power to this the problem gets even worse. The Perrin Fuel Rail Kit solves those problems. By redirecting fuel to both banks of cylinders as well as the regulator, even fuel distribution is guaranteed. Kit includes billet aluminum rails with stainless lines and fittings. This part is designed for use in all WRX'S. However, aftermarket electronics are strongly encouraged.
Vishnu Fuel Rail Kit $494.99
Don't believe for a second that the stock fuel system is capable of safely supporting much more than 300 horsepower. With 420cc/min injectors, it's not very hard to run the fuel injectors well beyond their safe operating range. This comprehensive upgrade package includes two high-flow billet fuel rails, an adjustable high-flow fuel pressure regulator, fuel line and all necessary mounting hardware/fittings. Not only does the parallel-fed fuel rail configuration ensure that all cylinders get equal fueling, but the adjustable FPR allows the user to increase fuel rail pressure over stock levels which, in turn, yields more fuel flow and safer engine operation.
Hmm...
wenn ich die Teile so sehe und Stukkis Beziehung zu Stahlflex-Anbieter müßte es doch möglich sein durch den Kauf eines Sets und Nachbau das Ganze auch viel günstiger anzubieten oder ? (was sagt eigentlich der Tüv dazu?)
