At Walter Motorsports, we know the Porsche G50 is legendary. It’s the gearbox that brought the air-cooled 911 into the modern era with its hydraulic clutch and robust Borg-Warner synchronization. But even legends get tired, and with today’s engine builds pushing torque figures far beyond factory specs, stock units often struggle to keep up. As the premier destination for custom-built transmissions in Fort Worth, we specialize in taking these classic transaxles and transforming them into modern powerhouses. Contact us today.
Porsche G50 Transaxle: Rebuilding and Reinforcing a Classic for Modern Power
Precision Blueprinting & Teardown
Every build starts with a meticulous teardown. We don’t just replace worn parts; we blueprint the entire assembly. Many Porsche transmissions from the late '80s suffer from worn synchros, tired bearings, and shift fork play that kills confidence on the track. We inspect every gear face and shaft tolerance to ensure the foundation is dead straight before we even think about upgrades.
Reinforcing for Reliability
To handle increased output, we go beyond a standard refresh. For a true Porsche racing transmission, we swap out the factory brass cages for steel, upgrade the shift forks to prevent deflection under heavy load, and apply cryogenic treatments to the gear sets for maximum durability. We reinforce the areas prone to flex, ensuring that when you drop the clutch, the power goes to the wheels, not into twisting the case.
Tailored to Your Drive
Whether you need a daily-drivable restoration or dedicated racing transmissions for the circuit, we tailor the build to you. We can alter gear ratios to keep your engine in the powerband or install limited-slip differentials for better corner exit speeds. We don't believe in "one size fits all"—we believe in building the transmission your specific car deserves
