injectors and an FMU

[newaccorddriver]

i was wondering if i must use an FMU with larger injectors. i was reading something from G2IC and it says that factory turbocharged engines dont need rising rate fuel pressure regulators but instead use larger injectors.

if i use DSM 450cc injectors, would i still have to use the FMU or would i be safe using my stock FPR

do not use an FMU. Stock FPR will be fine for boost

atleast i dont have to buy an FMU for my setup. what about fuel pressure, is stock fuel pressure enough to support the extra air? i guess a new pump would fix that problem as well

dsm 450cc injectors are good to a ballpark of 300hp. If youre going for over 200whp then you need to get a bigger fuel pump, a walbro 190lph or 255lph intank will work good. Stock fuel pressure is fine

basically all i needed to know

is the only difference between the walbro 190 and my stock 190 just the fuel pressure it make?

stock is like 70lph i think... walbro 255lph intank supports 550hp or so
