    Default injector sizing?

    G'day guys
    I want to get my fuel system finalised and finished before December,
    The engine is a 3T-G Running a Microtech ECH, 45mm INjection perfection ITBs, hot cam,double valve springs, nitrided valves, ports, approx 9.7:1 comp ratio, all been balanced etc

    I was wondering what sorta injectors i should get, casue they are quite a distance from the valves i want a fine pattern, but im more worried about flow, i was thinking of just getting 4AGZE injectors to get it running, then do some research on injectors with the right flow and pattern
    suggestions?
    ATM i have a few sets of bosch 280 150 736 laying around and also can get injectors that were used in the BMW E30 325i (cant rememebr engines, i should know i play with them alot im thinking M24)
    but i dont think the first will have the flow and the latter the patten

    Cheers
    Rohan

    best bet is what HP you want and work out the injectors from that.

    ive got x6 2jzge ones going for cheap if youre interested

    315cc @ 38-40psi
    based on 85% max duty cycle, they should be good for 45-55hp each depending on BSFC

    easy to push that to 45-48psi as req too
