is a fpr or fmu nessacary?
here is my setup, 450cc injectors 190 walbro fuel pump, hi flo fuel rail. im going to be running a t25 on stock boost, around 8-10 psi, i have a b&m fpr but wont fit my setup, will it be safe not running a fpr or fmu with a hi flow fuel pump?

your car is allready equiped with an FPR.You dont need another one.
FMU+8-10psi=B00M!
If you want to run the 450s you will need an AFC to cycle them.just the 450s alone will flood your engine with fuel and it will go nowhere.

the fpr is on the fuel rail, it has a vacuum line going to the top of it, and your fuel return line coming from the bottom, it's just not adjustable like the aftermarket ones. if you use the 450's, you either need an afc or to chip your ecu to control them, or else, think about it, with nothing to control them, you'll be dumping twice as much fuel in your engine as the stock injectors (240cc). if you want to use an fmu, you don't use the 450 injectors, you keep your stock injectors in, but don't plan on boosting more than about 6 psi.

sooo. lets say you are gonna use TurboEdit with 450cc DSM's and a 255lph walboro, would you need to buy an adjustable FPR? Sorry for teh jack, but Needed to know and didnt see the need in creating a new thread about it. Looking at 10 PSI daily on a SC50.

i should have said whats its in. its a 97 dsm eclipse gs it was a non turbo. i bought a b&m commando and it wont fit my fuel rain niether my stock nor my hi flow. i thought was since im running a hi flow fuel pump, with upped injectors i may not need a fpr but then again my may need one, i havent been able to find on for my 420a just universals.

you will still need something to electronically scale down the voltage to the injectors, or else they will dump too much fuel in, you can not control them with an adjustable fpr, period, it doesn't matter if it's on a civic or a space shuttle, the principal is the same.
