What Size Injectors To Go With A Gtrs?

[series2r33]

Im about to by a GTRS turbo but im not sure what size injectors to get. I was gonna get the nismo 555cc because i was tossin up between the GTRS and the GT3040 but i've decided for a car predominatly used on the street the GTRS is the go. Anyway i was wondering what everyone else thought about the injector size?

perfect.

Get the 555cc, they will be just right, should be at around 60-70% duty cycle at 280rwkw?

[Birnie]

Would the S15's be up to the task as a cheaper option?

Although i would only consider it on the assumption you aren't going any bigger on the turbo.

Seem to be 450cc (even though rated as 480cc)

I'm close to getting em tuned on the HKS2535 so I'll see what the % goes up to on a 250rwkw tune (hopefully )

Birnie I'm going 440cc bolt-ons for the GTT because I don't plan to go for anymore power then what my GTRS can push out, it will hopefully be enough to provide to close the max of the turbos potential. Hopefully having no more room for power due to the squirters maxing out will make not spend anymore money.. hahah hopefully

440 bolt ons for the R34, you can use GTR replacements can't you? or is that what you're tallking about?

Well keep us updated casue if they are up to the task, the S15's would definately be OK for the R33

[Devils_Advocate21]

555's are perfect size for those turbos the gt3040 maybe a little higher but you never can go past the Fuel reg option with the 555's if you need that little bit extra

So would the S15 stock injectors be up to the task of running a GT3071 (475hp) and also would they be a direct replacement to the stock r33 injectors? also im only lookin at around 260kw.

The only GTRS's i can find have the T28 flange and need an adaptor to be fitted to the T3 flange. Thats why im goin for the smallest T3 flange turbo which is the GT3071

[wolverine]

the HKS GT-RS for RB25's is T3 flanged and comes with all parts needed to bolt on. nengun, greenline and numerous forum sponsors could supply one if you are looking for an easier bolt on option.

[series2r33]

You mean this turbo? for AU $ 2,150.73

Is there a garret the same power?

This doesnt say its a T3 flange, it may just have a reducer from the flange to the turbo included in the kit? maybe?

[wolverine]

the RB25DET version is T3 flanged and includes all the fiddly bits you will spend time and money chasing when you need them.

I am using 480cc injectors on my R34 with GCG highflow turbo. Turbo I think is only a little below a GTRS. With cams at 270rwkw (Unigroup Dyno) I am very close to maxing them out.
