Basically the above. Im currently running stage 1 with filter and tip, and in all honesty its not as quick as i hoped. ( this isn't down to the cars performance, its performing fine and the engine is perfect) ( its due to me getting used to it, and having bigger powered cars) If i carnt get the car to a better reliable power, then ill sell up for a e46 M3.... By "better reliable power" i mean; just as reliable as now and quicker haha I don't want to do any internal engine modifications, just external mods, e.g. turbo, manifold, fmic etc. Id like the car to pull more, and just have more power in all honesty. So what are my best options? Turbo wise? TFSI turbo? What turbo are these? Or a hybrid straight fit unit to a S3 8L? I don't care about figures, just how it responds.
