Most of the guys in the FWD SR20 Community that I have noticed pushing decent power are all doing so on stock fuel lines, with only Walbro 255, upgraded injectors and fuel rail, and adjustable fpr.

At what point does one really need to upgrade to larger fuel lines? I'll only be hitting 400whp hopefully after my initial turbo kit is installed, but I expect to proceed over to 500whp once I install my cams and turn the boost up some more.

So I guess in general, at what point should a person upgrade fuel lines and to what size is best suited for 500+ whp applications if so.

Thanks
