Well....admittedly, that is what I labeled it....but maybe it qualifies.

3.0RS build:

• JE, 9.5:1 pistons
• Webcam 149/149 cams (Early S cam grind)
• TWM/Borla Independent Throttle Bodies
• SSIs
• Sport Muffler

Stock 911SC 3.0 was rated at 180HP/5500 at the flywheel, 204HP/5900 flywheel for later ROW

This "3.0RS" engine dyno'd at 206.57 at the wheels...so, using the typical 15% drivetrain loss calc...that 243 at the flywheel (35% increase over 180HP, 19% over 204HP)

To compare:
The 1973 911S was rated at 190HP/6500 flywheel
The 1973 RS was rated at 210HP/6500 flywheel (10% over 190)
