We specialize in working on
turbo BMWs

ChanceBuilt Performance is a BMW specialist shop in Riverside, California. Not a general repair shop that happens to take BMWs, but a shop that works on the same handful of engines every single day and knows exactly how they fail, how they respond to boost, and what they need to survive it.

That focus is the whole point. When an S55 comes in with a misfire under load, we are not guessing. When someone wants 700 wheel horsepower out of a B58, we can tell them what that actually costs: in parts, in fuelling, and in how long the car lasts afterwards.

We do the tuning in-house. We do the fabrication in-house. And we would rather talk you out of a bad idea than take your money for it.
