FPR Needed?

[Seven]

So I'm planning on putting in a walbro and some 555 injectors to (along with some other stuff as well), was wondering if I need an adjustable FPR?

If you are still running the old stock one I would replace it at least with a Nismo unit. The Walbro will hasten it's demise.

Yes. What ECU do you have by the way Ryan, it's not going to run with either with managment. The nismo one will bolt into the rail as oem.

Also, check out STI injectors. Much cheaper than the Nismo Injectors, and whilst different with "CC", support the same 'basic' power.

Run stock all the way up to 500 whp for 2-3 years no problemo..

I would not get the on rail Nismo if you are looking at one look at another rising rate unit like SARD or ARC or something that is a bit more robust and off rail preferably.
