The SX-R B2BV is a BorgWarner direct-fit upgrade for the factory B2BV turbocharger on the 6.6L L5P Duramax. It uses an SX-R forged milled compressor wheel with a 64mm inducer and extended tip technology, and supports up to 600 hp with appropriate supporting modifications. Each turbo is supplied with a new actuator and an installation gasket kit, and the part is year specific: the 2017-2019 unit is not interchangeable with the 2020-2023 unit.
