    Question VXR injectors and 4 BAR Regulator ??

    Having real trouble sourcing some resonably priced 550cc or 660cc injectors for my z20let that will run on the ecu. Tried some 550cc from motorsport developments and they overfuelled like crazy for some reason ??

    Was thinking of maybe running the vxr injectors with a 4 bar reg ?? any ideas whether this would be ok ?

    Gonna be coming close to the 400bhp mark so need to know they will cope ok

    Cheers,
    James

    Did you remap when you put the injectors in?

    Should see around 380/390 bhp with the vxr`s at 4 bar mate, mine did 355 bhp with 3.5 bar on vxr`s. I should be back down end of next week if i get the car back in 1 bit.
