T3/T4 doesn't suck if you plan on this being a daily driver, I decided not to swap to the T3 60-1 as Turbonetics told me it is not a very streetable turbo and they said unless I am going for an all out race machine that the setup I have works better, although yes you do get more CFM's so it depends on what your going for. I need daily drivablity as I drive this car everyday, but if I was just using it for racing than I would definately get the T3 60-1.
