I've noticed some front-engine cars with an aftermarket turbo conversion feature rear-mounted turbos. What is the exact purpose of mounting the turbo in the rear of the car, far away from the engine? Wouldn't the boost pressure also gradually decrease as it has to travel a long distance to get to the engine compared to a turbo that's mounted in the engine bay, where the piping is much shorter? My theory is the engine bays of some cars have no room left for any turbos. I've seen this rear turbo setup on some Corvettes and 350Z's, but in some cases the turbo(s) are actually mounted in the engine bay, which kinda rules out my theory of a completely full engine bay.

This strange turbo setup doesn't really make sense to me, so my question is how is it in any way practical to mount the turbo(s) in the rear of a front-engine car?
