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. 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.
This package uses all Genuine BMW parts. It includes everything that needs replacement during a 335 N54 twin turbo overhaul -
BMW rebuilt turbos have a two year warranty.
Each turbo has core charge each that will be refunded once your original rebuildable turbos are returned.

Vargas is among the first turbo specialists to release a Stage 1 upgrade for the S63TU V8. Using the stock housings but with improved internals, this S63 turbo upgrade is good up to 800whp. Stage 1 is a hybrid of stock and upgraded internals - a new larger higher-flow billet compressor wheel with specially machined housings for much improved flow characteristics. These are the first step in building an X5/X6 M super sled!
Vargas Turbo Technologies has been in business since 1979, offering rebuilt and re-engineered turbo solutions. Vargas rebuilds each turbo assembly with OEM or better internals, addressing known weak points at the same time. Because the Stage 1 uses stock turbo housings, all of the stock turbo plumbing and intake hoses will match up. It's recommended that the rest of the system be upgraded to handle your tuning goals. Custom software tuning will be required to achieve the correct fuel and timing curves.
Oil Recommendation - modern engine oil is formulated for emissions and to be environmentally friendly. The additives in current oil lowers the oil's ability to withstand high temperatures and stresses, lowering its shear strength and its lubricating properties. Vargas recommends oils with high ZDDP (zinc and phosphorus) content that will better protect and cool the turbo bearings. Examples of high-zinc oils are Red Line Race, Red Line Euro, Motul 300V Racing, Joe Gibbs Racing, Valvoline VR-1 oil, and most Diesel-spec oils that you can buy off-the-shelf. Some oils, especially the Race type, will need more frequent oil changes and may be harmful to catalytic converters.
WHP rating: 800. This rating is used to compare various stage of Vargas turbo kits. The number is a theoretical limit for how much power it could make. There is no advertised horsepower gain without consideration for additional tuning and upgrades. The rating is provided as a reference to use in your tuning planning.
Vargas turbos are rebuilt on an exchange basis so a core charge will apply. This will be refunded upon the return of your rebuildable original turbos.
