its a HKS legal

they are not designed to really push more than street application

so you need to change for a good flow on 600/550

change the turbine outlets, down pipe to something better (HKS is ok, but much better options out there)

all the best in your search

il be going for similar power, so i went Midori turbo outlets, tomei turbos, midori Ti down pipe, midori Ti Muffler

hope that helps.
