CP Piston & Ring Set 78-83 Porsche 911SC 3.0L - 95mm Bore - 45.5cc Dome - Compression Ratio (10.5)

If you're rebuilding the engine in your 1978-1983 Porsche 911SC with the 3.0L engine, this CP Pistons forged piston and ring set is built for serious performance. These pistons are designed to handle the demands of a high-performance air-cooled flat-six, offering a significant upgrade over stock components for those looking to extract more power and reliability from their engine.

Each piston in this set features a 95mm bore and a 45.5cc dome volume, which works out to a 10.5:1 compression ratio. This compression level is ideal for naturally aspirated builds aiming for improved throttle response and power output, while still being manageable for pump gasoline in many setups. CP Pistons are known for their robust construction, utilizing high-strength forged aluminum to resist detonation and withstand higher cylinder pressures. The included rings are matched to ensure a proper seal, critical for maintaining compression and controlling oil consumption in these classic engines. This set is a popular choice for enthusiasts looking to refresh or enhance their 911SC's heart.

This set is intended for performance engine builds and requires professional installation. Please note that these pistons are not CARB approved and cannot be shipped to California. Always consult your engine builder or a qualified mechanic for specific installation procedures and compatibility with other engine components.
