You can get the Raptor performance numbers out of a regular 3.5 with a good custom tune. I did some searching and did find out that the Raptor turbos have different compressors. The Raptors also have Stainless exhaust manifolds, where the normal EB has cast iron manifolds. Catback is different as well. Other than that, everything else is the same except tune with a little more timing and boost.
