N54 Turbocharger Overhaul Kit, BMW - E82 135i

Do your N54 turbo overhaul job right! This very comprehensive kit for the 2008-2010 135i coupe and convertible includes two brand new OE N54 Turbos (made by Mitsubishi, the original supplier to BMW) as well as all of the commonly replaced gaskets and hardware for replacing turbos on 2008, 2009, or 2010 model 135i. Not for RHD models.

This full package is specifically for the E82 135i coupe & 135i convertible models with the N54 twin turbo engine. Our included hardware kit uses a mix of Genuine BMW and OEM parts - nothing aftermarket, suspect, or from a brand we wouldn't use on our own BimmerWorld employee or project BMWs. These brands include Genuine BMW, Elring, and Victor Reinz, all of which have a two year warranty.

When replacing the N54 turbos on the 135i, 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 for many with a shop lift 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.

Both Turbos are brand new, made by Mitsubishi, the original supplier for BMW. You can be assured you are getting the best quality OE / Stock turbos, with absolutely NO CORE CHARGE or core return hassle. You're also assured you're getting the latest design improvements available. All of the included hardware this kit is either Genuine BMW or OEM. We assembled this kit to make it easy for you (or your mechanic) to get the right parts easily, and at the best price. All parts include a two year warranty.

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.
