about the full T28 rebuilds. Unless I am mistaken most people refer to the name T28/T25 turbos thinking they have bigger exhaust wheels, when in actually they do not. Most rebuild companies that sell the stage I upgrade that people refer to as T28/T25 only upgrade the compressor wheel and leave the turbine wheel stock so what you really have is a T28/T22. With intercoolers I do not think these turbos are bad, however I am upgrading to GT2540s so its only a matter of dissiminating information for me.
