Sr20 fuel system Capabilities?

[Toddtravers]

I am wondering how much hp s13 240sx/sr20 stock fuel rail and fuel lines can handle My current set up is a nismo afpr 340 Stealth and 810cc injectors I'm Going for around 430 to 450 whp

Youll be fine, I made around 550whp on stock b13 fuel lines which is the same size lines as the 240sx and with a walbro 255lph pump. 430-450whp is easily doable. Did it on pump gas.

Now if you were trying on e85 that would be a problem. You could probably squeeze 450 out of the stock lines but you would need more than 810cc injectors. ID1000's and e85 on the stealth pump and stock lines should be able to accomplish that

It will be on 94 pump thanks
