When replacing the N54 turbos there are many parts that must be replaced and some that are simply a good idea to replace. This kit covers both and sits in between a minimalist kit for the ace DIYer and the ultra kit for the DIY or shop that wants a completely fresh install. It should be noted that while replacing turbos can be done with the car on jack stands, "the easiest" procedure is to drop the subframe, suspension, engine, and transmission from below (a lift is essential here). This allows infinite access to the parts. Depending on which procedure you choose, additional parts may be required - see below for links or contact us for advice.
Note for 335xi models: more parts must be removed to access the turbos on Xi AWD models. This may include the axle shaft, subframe, right side engine mount, and steering rack. How much you remove is dependent on your abilities and tool chest. All of the parts in this kit are common to the Xi models, however, there may be other parts needed depending on how much more is removed for access. Contact us via phone or email for a group of parts we have available to assist you.
All of the parts in this kit are Genuine BMW or OEM - the original supplier to BMW for some of these parts. We bundled together all of these parts for special kit pricing. All parts include a two year warranty.
