    fuel injectors and pump help

    Ok so I'm a Noob I have a 2008 Wrx sedan and I went Lil crazy with my money and I brought 1000cc injectors, fuel pump, down pipe, up pipe, CAI, ap, all Cobb besides the fuel pump. I have installed the CAI, up and down pipe and tuned to stage 2. There is no e85 around where I live. Should I still install the pump and injectors and if I do what do you think my HP would be on a stage 2?? Please don't beat me up on this. Like I said I'm a noob. Thanks

    From what I know (which is not a whole lot), changing the fuel pump and injectors correlates with changing the turbo. Besides that, it would be a waste of $$.

    You would not really be maxing out your stock fuel pump and injectors at stage 2. To get some advantage out of the fuel pump and injectors, I would next invest into a quality top mount intercooler (PW and ETS are a few to look at). That way you can up the boost and get a more aggressive overall tune going. One other necessity at this point would be a quality bpv (by pass valve, fully recirculating, not atmospheric), such as the forge unit. The stock unit is plastic and known to fail at or above stage 2 power levels. One thing to keep in mind is the tuning route. You obviously won't be able to be running an off the shelf tune such as COBB maps any longer. You will have to get custom tune, either a live dyno, or an e-tune (such as phatbotti or TP).

    The 2008 had sufficient injector overhead for stage 2.
