Kind of depends what power you are wanting to achieve. With a 16T fitted I reached 235bhp and 450NM but that was with bigger nozzles and a host of other mods. Just strapping a bigger turbo on will do nothing even at 1.5 bar if you haven't got enough fuel to go with it. Currently I have the k14 back on running 1.3 bar and a tuning-diesels box for extra fuel + bigger nozzles, I hit 191hp and 410NM last dyno. But be prepared to replace clutch after 170bhp, I know mine was old but it wasn't really upto the job either way. Oh, you will need a 3 bar map to allow the extra boost too.
