This service is mainly tailored to BMW supercharger owners that have a good condition Vortech supercharger that needs standard reseal and bearing rebuild. Damaged impellers, cases or otherwise will be handled on a case by case basis.
Any Vortech V1, V2, V3 can be rebuilt and doesn't need to be specific to a BMW as the chargers are generic in their fitment.
