When replacing the N20 turbo 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. Additional parts may also be recommended - see below for links.
Oil Supply Line: BMW has issued numerous revised parts for the oil feed line going to the turbo. The original design would allow oil to leak back into the turbo after the engine was shut off. This resulted in blue smoke on cold start-up. BMW will replace the oil supply line as part of the emissions warranty but we do offer it separately if you are out of warranty or it was already done.
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.
