Most cars that are turbo'd like the 135i and more notoriously, the Evo, come very rich from the factory to protect the motor, but more-so to meet specific marketing criteria for a horsepower rating. If you lean out the mixture and add a few more pounds of boost, its not gonna kill the motor. I'm at nearly 52,000 miles on my tuned '06 Evo and I beat the snot out of it on a daily basis...no motor or turbo problems whatsoever *knocks on wood*. If anything, the clutch and/or tranny go before the motor.
