Pie cutting the wishbones is a fairly simple operation (one of the simpler actually) but only if you don't mind cutting them in the first place! The T5 is one of the easier transmissions (thus it's popularity) to install, so than in and of itself is not the issue. There is not much that will fit through the x-member without some modification. And unless you are retaining the closed driveshaft the whole rear assembly has to be addressed with the same wishbone issues and/or some other type of radius rods for the rear axle (unless you go to parallel springs which have their own set of challenges).
