R33 GTST S2 Injector Advice

[jameskhorne]

Hi Guys

I'm taking my car in to be tuned at the start of November, I'm thinking I will do injectors and Higher flowing Petrol pump But need some advice,

She already has the following

Return flow front mount

3" exhaust turbo back

K&N Panel Filter

Hi Flowed R34 Turbo

Yellow Jacket Coil Pack

Apexi Power FC

I figured the injectors and the pump would be the only thing holding it back from making good power?? Thoughts??

i put injectors from an s15 and and an aftermarket fuel pressure reg in mine and got good power out of my tune with the other mods i put in i went from 180kw to 240kw

Depends on what kind of R34 highflow you have - who did it and what kind of power did they promise? Injectors and AFM will max out at roughly the same time so you could just go with what you have and get 220 - 230kw

Hi Guys

Thanks for the reply, I have the receipt for the turbo but it doesn't give me Much information,as it was done before I bought the car, Do u guys recommend doing the fuel pump? Do u know what kind of power the standard fuel pump can supply?

Injector Size recommendation to support?

What company is the receipt for the the high flow from? An upgraded fuel pump is a must. If your only going to use 98 unleaded, a hardwired walbro 255 will be fine. For E85, a hardwired  walbro 460 or DW300 will do the job. I would suggest some modern top feed injectors, 1000cc would be good for future head room and they still idle perfectly from what people say. Just stay away from cheap shit high flowed/re drilled junk injectors.

If you think you are going to make mega power you will need a Z32 AFM (and some kind of boost controller).
