The engine is taller than the gearbox yes, but the engine is also in front of the gearbox and some distance away from the rear wing.
No, the champ car layout doesn't mean exhaust flow the way you describe

Flow to the rear wing is irrelevant if we are talking horse power here.
Especially when that turbo exhaust can blow under the wing!
Yes, you would be forced to turn the turbocharger 90 degrees so its shaft is parallel to the cars center line.
Regardless of the exhaust flow, you don't want the turbocharger to hinder the airflow to the lower rear wing. When you've gone to a lot of trouble to remove all the suspension parts from the upper part of the gearbox, you don't want to add a new component there.
