visually the GSR will feature:
a DOHC VTEC badge on the rear a lower ride height and premium wheels.

on the inside:
the tachometer will read to 9k rpm and have the redline start around 8000rpm, the dash will say "premium unleaded fuel only"

under the hood:
the car will feature a DOHC VTEC valve cover, and the intake manifold inlet will be significantly lower than one might imagine, the intake manifold is also a crazy looking peice of equipment on GSR's.

the engine stamp will say b18c1 and feature a head with the stamp P72x
