what size injectors ?

[Jason84]

well getting a evo3 16g apexi safc walbro 255hp aeromotive FPR a nice big fmic the spearco 216 and a pocketlogger.

but what size/brand injectors should i get ? i was thinking about 650-660s is that to big ? and what brand is the best to get ? seams there is to many out there to choose from.

 

[allwheelTSI]

550's would work well.. but it would'nt hurt to get the 660's,that way you'll be able to upgrade the turbo again without doing the injectors.

 

[allwheelTSI]

oh yeah,both RC and ND are good brands for injectors.

 

[Sephroth57]

well youre never really too big unless you get hugely over what your turbo needs. id say get 660s, you could probably max out that turbo with them plus you wouldnt need to upgrade as bad if you ended up goin bigger

 

[Jason84]

k guess ill go with the 660s

what brand you suggest sephroth

 

[peregrine]

if you get 660s you better make sure that you get an afpr also. youll need to back off the fuel pressure as youll be pulling out so much airflow signal that your timing will be through the roof. thats bad on pump gas. go with the 550s unless you plan on poutting a 50 trim or larger on there fairly soon.

Brand wise, I know Hahn makes some crummy turbos but their injectors are supposed to be top notch. I would suggest some HRC 625cc injectors, or if you go 660s go with Denso.

 

[Jason84]

yeah im getting a fpr and probably a new fuel rail to.
i might just buy an aem fpr and fuel rail.. not sure which brands im going with yet.

 

[peregrine]

why a new fuel rail? save your money for something else. i thought dsmers were cheap. maybe we're a dying breed........

 

[Megaman]

i thought a 190 pump and 550's would be effecient enough for this turbo?

 

[Jason84]

well ive got the money... this turbo is just to hold up till next summer.

then im probably going with the forced performance fp30 unless something else new comes out.

I my self like the Bosch injectors.The spray pattern of the ball and disk style they use is so much nicer than the old pintle style of RC and denso.
I would get the 650`s you can always lean them down durring the tunning stage. I wish i had got 750`s. i have run out of full with the 650`s on my set up.

Spray pattern difference
