Hey, Im working on some planning for my turbo motor, right now I have a aluminum fuel rail for the stock injectors on its way. Il be running 12psi of boost on a mostly stock turbo motor and over the last week or so have been doing research regarding the fuel system and getting more fuel on boost.
My question is do I use the stock regulator off of the stock fuel rail? Or will the 1:1 fpr replace it. *** From what Ive read the fpr that will give me extra fuel on boost is added in addition to the regulator.
I feel overwelmed with all the info Ive been reading about regarding fuel pressures, fmu's, afpr, fpr, etc. and all of these being used together.
If I need to include any addition info just ask.
*** maybe not the correct term but the regulator that will give me 1 extra psi of fuel pressure for every psi of addition boost. Still researching it.
THANKS!
Edit- Thought Id include a little info on the motor, f54/p90, stock turbo cam, intercooled, stock tubo afm, ecu, harness, n42 intake, stock injectors, aluminum fuel rail, DSM BOV, external wastegate/proper downpipe.
