    Question

    Which size inj's are best for a now 6 psi D16Z6? What if I get the blower modded and increase the pressure later? I'll probably go with Venom 290cc's or 310cc's I think. Please post your recommendations. Jim, what kind of deal can you get me? Thanks. Tom

    Jim's out of town right now. I've been told that 310cc-320cc injectors work well on modded JRSC civic's. Make sure you get an adjustable FPR and maybe even a Cartech to replace the JR FPR

    Tom - Remember Jim's out of town. Any ways, I have the RC 310's(paid $200 used) and they are too large for our application @6psi. Here you go:
    JRSC @6psi: 270cc injectors(help out w/ mild detonation problems)
    JRSC @8psi: 270cc injectors
    JRSC @10psi: 290-310cc injectors
    Endyn JRSC : 310cc injectors(Too recommended)
    ZDYNE ECU Upgrade: 440cc injectors

    Tom, what are your dyno #'s or 1/4 et's. Let me know.

    I'm using 310's. They will be a bit much for 6psi, but if you upgrade later, it's cheaper to buy one set now, and be done with it. Don't buy, say 270's, and then have to pay, AGAIN, for 310's...like I did. You've got a field controller, you can adjust it to richen and lean it out. Get the big ones, drop your fuel pressure at idle speed with the B&M/cartech, and tune with the field unit. It'll work. You've got everything you need.

    310's should work well... but only if you get pintal style injectors like the stock ones... This is why people have problems with the 310's at low rpm, it's because mostly they buy the RC's... which are disc style and dont atomize the fuel properly. They work better at higher boost level because there is more airflow to blast apart the fuel.
