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, just as if you went to the local dealer parts department (but bundled together for special kit pricing). All Genuine BMW parts include a two year warranty. We also offer this kit with OEM or aftermarket parts that offer the same quality but with more savings.

Are you reusing your original oil supply/return lines?
In some cases, the turbocharger oil lines can be reused. Careful inspection is highly recommended. Aging oil lines are a common source of leaks. The oil supply and return lines can also become kinked during the turbocharger removal process. If you suspect that your lines have been bent or damaged, it is wise to replace them preventively. Another reason to replace the N54 oil lines is that the lines can become plugged and restricted by burnt oil residue, causing the turbochargers to overheat and fail. If you're replacing your turbos, we recommend replacing the oil supply/return lines while you're in there. See below for BimmerWorld Recommended Related Items.

Don't forget to prime your turbo(s) with engine oil before running the engine!
