    wanting more power !!!!!

    im wanting to make my ef faster.
    its a fully forged b18c its already got
    320cc injectors
    walbro 500hp fuel pump
    adustable F.P.R
    type r cams
    type r head port n polish etc
    adjustable cam pulleys
    steam pipe manifold
    38mm tial gate
    t3 turbo
    XS power intercooler small but 100mm thick
    hondata s300 ecu
    etc
    at the mo its only running 216wkw on 14psi and that seems shit on a forged b18c
    i cant run it on 98 octane kos we havent got it in the naki

    i thinking of changing to a GT3540r is that the best turbo?
    maybe bigger injectors?what size?
    AEM fuel rail?or are they just realy for looks?

    please let me know what else i can change to make it faster other than the turbo.

    Re: wanting more power !!!!!

    Sounding pretty good there so far.

    Rule of thumb for injector sizing is 500cc for every 100hp - so 550cc will be good for a bit over 400 hp.

    The standard fuel rail and lines are big enough unless your wanting to make over 600hp!

    Use your walbro pump as a supply pump to a surge tank
    And get an external pump like an sx or Bosch to feed the fuel rail.The size of your external pump really depends on how much power you expect to make.

    A GT3540 is definately a decent size turbo good for around 700 hp.
    The GT3040 can make around 600hp and would spool up faster than the GT3540.

    What you choose really depends on how much power you want to make and what you will be using the car for mostly.

    Re: wanting more power !!!!!

    I am amazed you are getting that power out of 320cc injectors, I would definitely upgrade those! T3 turbo would be pretty much maxed out as well. A Garrett GT3076R with a .82a/r turbine housing would make the power you want very nicely, the "What turbo for 500hp" topic has been covered a few times on here.

    yeah i thought that about the injectors they were sold to me saying 520cc injectors but only found out the other day they are 320.so i would only have to change the turbo and injectors to get to the 500hp mark?

    Re: wanting more power !!!!!

    Yes you will definately need to change them to bigger ones. Go for slightly bigger injectors than you need. 700cc's will be more than ample!

    You will need to change your turbo - see above posts.

    You will have to go aftermarket to get >700cc injectors, you'd be lucky to find factory injectors big enough for 500hp on a 4cyl!

    brett, we need to put the wideband on it and see whats happening on boost, there maybe room for more boost yet! I would recommend fuel pump (surge tank) bigger injectors, more boost, and remap of your hondata ecu. Phil

    Re: wanting more power !!!!!

    yeah, i can tune it for now with those injectors and a bit more boost, but you will need more fuel for more power. I have a new knock meter turning up tomorrow as well so we can monitor the knock levels

    you dont need to go to a surge tank or a bigger fuel pump for your goals. bigger injectors and more boost!

    Re: wanting more power !!!!!

    I think your doing really good with those injectors, must be running some impressive fuel pressure!.
    Im with turbo teg in this.. more injector, more boost and more turbo.

    B-Series Horsepower to Part Chart.
