2017 Porsche 911 Turbo for sale in CA

For the Porsche enthusiast who appreciates engineering integrity as much as outright performance, this 2017 Porsche 911 Turbo Coupe represents a highly refined and professionally developed example of the desirable 991.2 platform.

Finished in timeless GT Silver Metallic over Saddle Brown leather, this Turbo was thoughtfully configured for the mature enthusiast seeking exceptional capability without sacrificing refinement, comfort, or long-term usability. The build philosophy benefited from guidance by Kim Nielsen, known for his engineering involvement in the legendary GMC Syclone program, with the objective of creating a properly sorted and exceptionally capable street-focused 911 Turbo.

In March 2026, the car received a complete By Design Signature 1000 forged engine build with approximately 600 miles since completion. The upgraded 3.8L configuration incorporates forged internals, upgraded cooling systems, Tial VTG turbochargers, and custom By Design calibration, resulting in a substantially stronger and more durable platform engineered to comfortably support significantly increased performance capability.

Unlike many modified performance cars, this example was built with a comprehensive supporting setup emphasizing balance, reliability, drivability, and overall ownership experience. The result is a remarkably composed and confidence-inspiring 991.2 Turbo equally suited for spirited driving, long-distance touring, or inclusion within a curated Porsche collection.

Factory equipment includes Front Axle Lift, Porsche Dynamic Chassis Control (PDCC), Burmester audio, sunroof, factory fire extinguisher, and factory 5-lug wheels. Additional upgrades include a GMG 200-cell catted exhaust system, Zunsport protective grille set, Porsche aluminum fuel cap, and a BlackVue front and rear dash camera system with dedicated battery backup.

The vehicle has also recently received fresh oil and filter services, injector cleaning, and a new cabin air filter. Included with the sale are the factory exhaust system, factory intercoolers, and OEM Y-pipe/plenum components.

A rare opportunity to acquire a professionally engineered and carefully maintained modern 911 Turbo built with the level of detail, restraint, and mechanical consideration typically reserved for long-term enthusiast ownership.
