    Hks gt-ss

    Im thinking of upgrading to a HKS GT-SS turbo on my S15 as I want to keep it low lag and responsive, but was just wondering whats the difference in performance between this turbo and the standard S15 BB turbo? I dont want to spend around 900 quid on a turbo thats going to be exactly the same...
