Ok, so i want to replace my stock r32 GTR injectors for some newer cleaned R34 GTR injectors

Do i need a Tune when swapping the Injectors? or can i just do a nice swap with no hassles :happy:

The R34 GTR injectors have been flowed ~480cc at 40psi base pressure with less than 1.5% variation between.

Thanks,

Jason.

Looking at doing the same to my R32 gtr. Injectors used in both models are identical but was going to have the car dynoed just in case. Was thinking of replacing the fuel reg from a R34 gtr too, but they have a different part number to an r32 fuel reg. Don’t know what the difference is but they are different. Does anyone know?

Yeah i'm not sure about the Fuel reg,

but are stock r32 gtr injectors the same size as the r34 gtr?

i thought they were 440c ?

If everything else is standardish (boost etc) you'll be fine. Stock ecu tunes are rich anyway, so if its 0.5 AFR leaner thats a good thing. To eliminate any possability get a power/afr run done on a dyno.

If its stock, reset your ecu as well after fitting the injectors as well.
