Wastegate Boost Spring 1.05 BAR

An Eibach-made wastegate boost spring for the 930 Turbo (1976-1989), a simple, inexpensive way to add reliable power without touching anything else on the car. It raises maximum boost from the factory's 0.80 Bar (11.6 psi) to 1.05 Bar (15.23 psi), a modest bump that stays well within the wastegate's normal operating range. Fabspeed also lists it as compatible with the later 911 Turbo, 964, and 965 Turbo through 1994.
