Steve, these turbos and their idea is a great one. But the BMW is an inline engine and the exhaust ports are directly on its right side. When installed, they do not go any lower than the bottom of the engine which makes them good for car clearance/water/dirt/etc... Here check this picture:
Now on the EG33 the exhaust ports go below the engine (obviously you know that). I dunno how you will manage to protect those turbos from all the above, but I would suggest you to install them in the fender wells.
