The NISMO unit will fit on your SR. It's designed to fit on all KA/SR fuel rails (unless you get the universal one that requires an adapter, but get the one for the 240 and you'll have no issues). It also maintains the 1:1 ratio from the factory.

Adjustable FPRs are really unneeded on a fuel system that has been properly tuned. What a lot of people tend to do with them is increase the rail fuel pressure to force more fuel through the injectors than they're rated for. This in turn will cause the injectors to operate over their max duty cycle and it's only a matter of time before something gives.

EDIT: Forgot to add the word ADJUSTABLE before FPR. FPRs are needed

I need to get my SR tuned. Standard FPR, Open BOV (older HKS that supposedly can't use the re-circ fitting), = too much fuel
