labwork K03 Turbo Turbocharger 53039880118 Replacement for BMW Mini Cooper S Models R55 R56 R57 R58 R59 1.6L Engine Water Cooled 53039700163 53039700181

The turbo was delivered promptly and works great. Even though it’s only advertised for the N14, it bolts up to the N18 on my R59 just fine. Only difference is the missing bolt hole for the coolant line bracket.

I installed this on my 2009 clubman R55. Factory turbo had the waste gate go bad so it was throwing the awful boost plausibility code and going into limp mode. Mini dealership wanted $7,200 for a new factory turbo. I paid $5,500 for the whole car 50k miles ago, figured this was worth a shot. I will say it says it’s a factory K03 but the compressor housing itself is a little larger than factory (pics attached) though the physical inlet and impeller seem to be factory. My turbo came very quick, clocked correctly, took roughly 8 hours start to finish but I also did a front mount down pipe new oil and coolant lines to and from the turbo and charge pipes all at the same time. Amazon and eBay parts all the way. Entire project was sub $600 and then I tuned the car through Maxxboost tuning on their stage 2 car feels extremely healthy now and pulls like a freight train. Very very impressed with this turbo so far. Will update if there are any future issues with love ruby, etc.For reference my car is an N14 car so can’t speak to whether it will work on an N18 but I can’t see a reason why it wouldn’t.

There is no measurable difference between this Turbo charger and the OEM. No point in paying for the average quality OEM component

So far so good.

Came quick and fits as promised

I was in a pinch and need a turbo quick found this one and started the install. i installed all new coolant and oil feed/drain lines, also preoiled turbo on first start. worked great till it didn't, now have a couple thousands play in shaft oil seal bad and making zero boost.

Installed this on a 2015 Clubman, as the original turbo was bad and smoking white like crazy.The price is very very good, compared to OEM and the build seems like good quality.The only issue is that usually parts come with screws, etc, so had to use the very hard to remove special screws on the older turbo without breaking them.Other than that, we’ll see how it holds up, looks very promising.
