Bigger Injectors

[RBJ3T]

Hey,

I need bigger injectors bad as under full load i'm hitting 97% on my injector duty. I don't really want to go to the trouble of putting on a fuel rail. I kow you can still get big injectors that screw in and I guess my question is what is the biggest size CC injectors I can fit into the RB25DET.

Cheers. She needs juice. lol

720 cc nismos, 550 nismos looking bout 700 o 800 a se but they fit the standard fuel rail

[R31Nismoid]

Nismo 550's will be more than enough for your turbo (they support 300rwkw no problem).

Largest - I used Nismo 740's for mine 369rwkw.

Stock Rail, Stock Reg etc etc.

I think Sard's in the 800 are also direct-ish fit

[Jmaac]

I think sards need a different oring to fit

i have high flowed standard injectors and using standard rail.. flowed to 720 cc

[scarface]

i got denso sard 800cc with stock rail and reg

396RWKW!!! Thats massive man! What are you running?

Cheers for the advice. I cannot wait to get all the kit on. Iv'e gone a bit silly but whatever yeah! Not long till all the parts come in and i'll be aiming for around the 290 RWKW mark. To tell you the truth i don't really want more than that. I still want to be able to drive her on the road.

Cheers

How much did it cost you to get hi-flowed?

Why do tuners tell me to get bigger then 550cc if they can handle 300rwkw

im looking at between 240 - 260 rwkw

Highflowing injectors are abit cheaper then getting aftermarket injectors but i hear they arnt as good, can anyone confirm this?

Because they are full of shit

No other reason, or they are trying to sell you something that you simply do not need.

Nismoid,

As I am at the stage of installing a whole heap of gear I need to make sure I make the right decision when it comes to Injectors. Can you point me in the right direction as to where would be a good place to get the standards flowed. Or even someone to talk to about this.

Thanks Mate!!

A good option for cheap injectors is 480cc ones out of manual S15's, they are a direct drop in for R33 RB25DET's.

I'm aiming for approx 260rwkw and 6 of these will easily suffice, and only costing me $280 delivered for all six.

There have been a number of threads with suppliers/prices and so on.

Just search with "hi-flow" "injectors" and you'll be right

Personally i wouldn't use hi-flowed injectors.

[SLYNE]

now the question is where do i buy injectors?
