stock bottom end LS, building the head right now. PnP LS head, crower 404's, titanium valve springs/retainers, greddy 4-2-1 header blah blah. What I need to know is, do I absolutely positively need more than a fuel pressure regulator, or fuel controller with just the head build up? In the future I plan on building a shortblock with civic type R pistons, which will have about 12:1 compression, then I will get a skunk2 manifold, new injectors fuel rail and everything...But for the time being will a FRP or SAFC be good enough for the built up head? People who know what they are talking about post please. I don't need false info.

 

bump

 

a FPR and SAFC will do the trick for now. you wont need a aftermarket fuel rail but a set of 310cc injectors would help in the long run when you get over 12:1CR.

also once you bump the compression up you will be needing some better engine managment. (hondata or custom chip)

good luck.
