Fuel Pressue Regulator??

I just bought new 1300CC injectors and a comp fuel pump .. Will I need a new Fuel Pressue Regulator to safely produce higher boost? And what fittings do I need -6 or -10 ?? Does it matter?

Do you have a new (preferably stand alone) ECU? I've not gotten new injectors yet, but from what I hear you need an upgraded ECU to control injectors larger than a certain cc (maybe 1000cc?).

Not sure about the FPR, just wanted to add that.

Yeah .. I have a PFC ... and I'm about to throw on BNR Stage 2 turbos so I need more fuel for higher boost but I'm just curious if I need a better FPR too ....

I don't think (could be wrong though) you need a new FPR then. There are many guys on this forum running 1300cc's without them. I'd wait for one of them to chime in just to be sure, but I don't think you need a new one.

You don't need a new FPR unless you go to 1600cc injectors which require a new secondary fuel rail.
