As much as I would love to keep the fuel system OEM, to my knowledge, there just isn't any OEM options that will support 300whp+ with injector duty cycles not at 95%. The S209 HKS injectors are only 650cc, and down the road when I plan for a twin scroll setup I don't want injectors holding me back.

The Cosworth CS400 does use a HKS 800cc injector kit I believe. But I feel like I am spitting hairs. The ID1050x is a damn good injector, and I am content with an aftermarket fuel system that would make instaling a Spec C manifold easier. Its a fair trade off I think.
