Hello, I have a 2011 n55 6mt car and want to make 500whp reliably. Just put a new motor in it with 50k miles and did king bearings. Car has inlet, outlet, catless downpipe, Vrsf street exhuast, turbosmart bov, 7.5in race intercooler, bms intake. I also just put a xclutch organic clutch so it can hold 800tq. I’ve seen that pure stage 2 or slightly bigger turbo kit like bigboost is an option but I just love the sound of the big turbos like 6266. What turbo kit and fueling would you guys go with looking at dg autowerks top mount or speedtech bottom mount. Keep in mind my motor is stock.
