yes you have the ko3 and small port head, so if you do upgrade to the ko3s the i dont think the gains will be as good as the agu ko3s.
the ko3s is relatively plug and play + MAPPING but if you want to fit a T3 turbo then you will need
*T3 turbo
*FMIC
*manifold
*custom downpipe
*Custom TIP
*bigger injectors
*4bar Fuel Pump
*custom oil & coolant lines
*wastegate (although some T3's come with internals ones)
