what mods have to be done to fit a t4 and its a t04b not a e is that the wrong turbo
Is this a t3/t4 or a full T4? If it is a t3/t4 you just need to follow the directions in the faq section. If it is a T4 you will need either an adapter or a new turbo to manifold flange to make it fit. The T4 inlet is larger. Most T4's also have a different way of connecting the down pipe and they use external wastegates.

Which T4? Is it the V trim, S strim or H trim? What turbine side? If it is a t3/t4 is it a stock, stage 2 or stage 3 wheel? If it is a T4 which wheel? O trim or P trim? What A/R on the housing? .58, .69, or larger? All this is important info. just putting on a t4 will not make your car faster. It might be very slow if it is the wrong combo. If it is too big it might not spool till 5000rpms or later.
