We are BMW engine rebuild specialists based in Glasgow, UK.

Here at Rosier Racing we specialise in BMW and M sport engines. We have rebuilt and still race many of the engines in the BMW 116i Trophy series, with many podiums and strong championship standings. Our engines also compete in the Armed Forces series, and have podiums in the prestigious Race of Remembrance.

From the inline 4s of old in the E30 M sports to the modern N45s and then the beautiful straight 6s, we’ve worked on them all. Please get in touch today for any of your BMW engine rebuild needs.

We can also run the N45B16 (116i Trophy) engines on our dyno based in Cambridgeshire if you require run in on your race engine and a power figure. We use the series ECU map and all the parts as they would be for the series on your race car.
