People never cease to amaze me... I bet if you asked about the "modified throttle body" and the flywheel, the person wouldn't even flinch.

FWIW...if memory serves (and it usually doesn't) The stock flywheel on my 90 CRX Si STREET CAR weighed in at 19 lbs., I had 5 lbs. removed and wouldn't want to risk taking any more off.
