6's will do the job quite happily, i don't know how big a jet of nos your going for but your restricted by your turbo, you do understand that don't you? Plus tbh your better off just remapping the car to get the best out of what you already have and save you a fortune on gas top ups

Its going to max out at around 270-280bhp, really nos is a waste of time, its used too quickly and you may as well just tune the engine with the turbo on, you cant push past what the threshold of that turbo is without causing issues, so save yourself the money and just have a remap to the best of what the turbo is capable of flowing (and at this stage 6's are more than good enough).
Of course saving the money on not putting a nos kit on your car means you could then upgrade to say 330bhp, this would require a new turbo and injectors and a remap of course, your engine would be getting to its max reliability wise and you wouldnt have to pay for nos refills.
