Anything above your basic TBE and hopefully some EM for it, will take a turbo upgrade, or at least a P & P of the stocker, injectors, fuel pump and upgraded intercooler, a 3 port BCS is suggested usually also. And of course a tune so the car runs properly. After that a good set of sways and endlinks,nice brake pads, SS lines, better fluid, for handling (along with at least somethign other than stock tires). Looks are all up to the driver and NO ONE else, since you will be the one stuck driving and seeing t eeryday.
