Turbos and other induction should affect engine size

[Eric.B]

The impact is mainly on either height or width

Or length. Like I said, they cram it wherever there is is space in the engine bay.

But yes, the most common places for a turbo is on the exhaust or intake ports to reduce lag, but as I said, they can be mounted anywhere.

The game doesn't go into this minute of detail, but I may, or may not make a bounty for it. I didn't add it for a reason though.
