    My car is 2001 AMK S3 with a JBS05 turbo, FMIC, 3 inch downpipe/ decat, Jetex cone filter
    The car was dyno'd when the conversion was done before the downpipe and decat at 311bhp,
    Before we start the "dyno lotto" conversation the car was fitted with a 4 bar fuel reg so the stock injectors could be used.
    From logs taken recently the injectors are very close to maxing out.
    The plan wih the cars future could still go either way. But the question for now is... what will give more power? My guess is a B5 tip and WMI, With the addition of these my guess is the injectors will max out.
    I remember reading on here i could use VXR injectors with the set up i would have with a few tweaks to the map.
    The other idea is MAYBE go bigger turbo. But thats about another £2k + easy.
    So am i better off buying injectors bigger than i need for now so i have scope for later possible plans or keep the costs in control and stay 4 bar with VXR injectors as they seem to change hands for less than £100 new.
