Stock Rb26 Fuel Rail Limits

[SiR_RB]

Hey guys,

When does the stock rb26 fuel rail need to be upgraded to an aftermarket fuel rail?

I've currently got the stock rail with a nismo fuel reg and 1200cc injectors,

But soon I've got ID 2000 going on and afew other lil things, currently running 410kw on e85

Also when going aftermarket rail, can I use the nismo fuel reg or can that only be used on the stock rail?

It depends more on the pump than the injectors. If you are smart you could run a PWM controlled Fuelab pump or similar and turn the flow down when it isn't needed, that way you might be able to use all the stock gear you have currently.

We're at 501kw on e85 so far with stock rail and reg.
