Evo 8/9 O2 Housing
In yet another installment of our never-ending quest for the perfect Evo O2 Housing we have utilized the new, ultra-compact CompGate40 from Turbosmart. If you're having issues with boost control and/or exhaust back pressure is overpowering the spring in your wastegate actuator preventing you from running higher boost levels this product is the answer! We recommend running this external wastegate in conjunction with your factory internal wastegate for the best of both worlds in regards to spool characteristics, boost control and boost capabilities.
Simply run a vacuum line to the external wastegate from your boost controller as normal combined with an additional vacuum line directly from a boost source to the internal wastegate actuator and you're all set, no additional modification necessary!
