[RC33]

Hi all i'm in the process of purchasing some injectors for my R33.The ones that i'm buying are nismo 555cc will they fit in the factory rail.Also the next service the car is having a High flow gcg stage 2 turbo,injectors,Z32,power fc, installed will i need a fuel regulator as well or am i safe without.I already have a bosch 910 pump.So what ya reckon.Am looking for around 300hp.

G'day Rick !

Long time no see mate.

I reckon you should be fine without the fuel pressure reg for 300rwhp

you should make more than that with a highflow, anyhow...

Considering the price of the 740cc Nismo's form Nengun and the likes, if you have not purchased already, buy those.

That was say you do a bigger turbo/motor a couple years away then you wont have to revisit it

And no, you will not need a fuel reg at all, with 555's or 740's.

Im using my factory one with my 740's, they are a waste of money and just a band aid solution IMO
