EL would be a must for the stage 2+ turbo kits pushing above 400 whp or someone who wants to squeeze every ounce of hp they can out of a part. Even then, no one can tell you that you can't run a UEL at that whp level.

Err.. okay, so, dmittedly, I have no experience with H-motors (boxers), but in a typical I4, you would be ditching the header in favor of an exhaust manifold when going turbo... how does this work with a boxer motor since the ports are split into 2s, with each duo on oposite sides of the motor? In a V6 or V8, also with split cylinders, you would twin turbo teh SOB and call it a day, but that would be overkill on this tiny motor.
