Injector Question: Inisght Needed - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Okay guys, I'm working on the KA-T setup on my S14 and had a question. I have a friend with a SRT-4 who just upgraded his turbo, injectors, and FMIC. He is giving me the FMIC, which is great. I need to know what the SRT-4 injectors are flow rated at and if I purchased a top feed fuel rail from ProjectNissan, would the SRT-4 injectors fit in? If so I could save a lot of money on this setup if it is feasible. Thanks for the help guys.

theoretically they should fit.....i believe they are rated somewhere between 270 and 370 but might be a slight chance its 450s....

only thing u have to make sure is if its high or low impedence

They also run 4 bar of base fuel pressure on there stock returnless system.

so would that mean they wouldn't work... I think I have found that they are 45lb injectors, which is somewhere around about 460cc I think.

No it was just something to consider about the stock flow rate.

So if they are 45lb at 4 bar, then that makes them 39lb at 3 bar/43.5psi which is stock 240sx base fuel pressure.

39lb is 409cc which is what sr20det purples flow static.

If they are stock injectors, if they are from an 04+ they are 450s, if they are from an earlier model, I believe they were 370-390s. How big of a turbo are you planning on? If you're going small like a t25 just get a set of 370s from a stock SR and be plug and play.
