505cc + FPR = 550cc INJECTORS?
As above, gonna buy some 505cc injectors, would they flow enough fuel to run a tdo518g on their own or would i need a FPR?
The car will have ported headers, fmic and all supporting mods. Cheers guys
The car is a 99 type r by the way!

I'd personally forget the FPR and 550s but fit 660s or 740s instead - that way the full potential of the 18g (with your supporting mods) can be mapped for, with more than adequate fuelling 
. Therefore, you should see about 350-370bhp from it!
I think the fuelling could be marginal on the 550s... even with an FPR?

Really that big injectors? Im sure i read (or got told)that 550cc would be ok? Im obviously after as much power as i can get out of it so maybe your right. 
Who out there is running an 18g and what injectors you using
Cheers

Broadley speaking the 550s on their own struggle to make 350bhp, IIRC from other thread/s.
Even 740s will be okay with the amount of airflow proviided by thetFMIC and 18g - I'm certain they won't be overkill.
Just get 'em, fit 'em and forget 'em. That way, you know they won't be holding back the mapper in his quest for max bhp/lb ft.
... Most frustratng if the mapper turns to you ands says, " I could've got a more bhp/lb ft if you had larger injectors fitted."

Mine is running at 94 %, FPR and std STI pinks (505cc ?) to manage 390 bhp !
HTH

P.S. Easier to just do the 660's and forget the reg. imho
