Known issues by generation
The Porsche 930 Turbo, especially in the earlier 3.0L variant, is notorious for turbo lag and explosive power delivery, leading to the 'widow-maker' reputation due to lift-off oversteer. Preventive measures, such as routine KKK turbocharger rebuilds, are essential every 80-120k miles. The later 3.3L variant improves drivability but requires attention to oil cooler lines and head-stud integrity due to high cylinder pressures. Regular valve adjustments every 15-20k miles are also mandatory. Collectors should be aware of the transmission's notorious notchiness in the pre-1989 4-speed models and the collector premium associated with the 1989 G50/50 5-speed.
