E9X 335i/xi N54 Vargas Stock Turbo Replacement Kit (Upgraded Rebuild)
Turbo maintenance has become part of our daily lives here. Our Service department does several turbo overhauls, wastegate adjustments, carbon cleaning, and upgrades every week. For the DIY owner, however, having a complete overhaul kit takes some of the stress out of 335 turbo replacement and this kit includes all of the basic items with a few improvements to make turbo life more enjoyable. It's highly likely N54 turbos will have to be replaced before 100,000 miles. Signs of a failing turbo are high oil consumption and blue smoke from exhaust (not from a leak or failing CCV system) because the internal oil seals are no longer retaining oil. Without critical lubrication and cooling effects from oil, the turbo shafts and bearings are usually the first to wear and that requires a complete rebuild. You might also see increased turbo lag or failure to hold boost, which is usually a sign of a failing wastegate or some other internal issue. With any internal problems the turbos need to be replaced.
Vargas Turbo Technologies has been in business since 1979, offering rebuilt and re-engineered turbo solutions. With the N54, they identified a need for both cost-effective turbo replacements and proven turbo upgrades. The biggest complaint on N54 turbos is the rattle from the wastegates. The factory wastegates have actuator arms that lose their tension very easily, resulting in an annoying rattle. N54 wastegate rattle is the biggest complaint we hear from our customers. Vargas rebuilds each turbo assembly with OEM internals and replaces the actuator arm with a stainless steel arm of their own design. The final Vargas rebuilt turbos are better than the factory rebuilds and at a lower cost! This stock replacement kit is recommended for up to 400whp.
