Aftermarket FPR on NA?

I don't know (as I have never done it) but if my engine can make 216 at 63% duty, it is possible to make 300 at 90% duty.

216/63 = 308/90.

Like I said, I can't prove it as it has not been done, but it should work that way (as long as the BSFC remains constant with a more powerful engine).

I think this is a mute point anyway, as there is no reason that the OP needs to worry about his fuel system for an NA build, if he goes lean from fuel starvation, he may lose power... It isn't going to mean an engine rebuild for him.

Thumper:
If I were you, I would take jerd_hambone and RETed's advice and worry about the intake manifold. you will see significantly more gains from prudent intake modifications than you will see from spending a lot of money on an already functional fuel system.
