Basically you want the turbo to draw in free flowing air as possible for efficiency
Already being close to the engine blocks hurts that
I noticed trucks with twin turbo setups will have them all the way in the rear of the the bed
There's top mount, bottom mount, rear mount. People that go with go with a rear mount setup often due it for the ease of installation and you can run bigger turbos cause there isn't much restriction on space.
