When it comes to Mitsubishi performance, Buschur Racing started the game. Founded by David Buschur nearly 30 years ago, our record setting performance propelled us to be the first shop to run 13, 12, 11, 10, 9, 8 and 7 second times at the drag strip with the Mitsubishi 4G63 engine. You will also find our parts on cars set up for the street, autocross, road course, salt flats and ½ mile tracks! We feel confident that outside of Mitsubishi themselves, more Mitsubishi engines and parts have been built here than anywhere else in the world. We ship our parts to many countries across the world. Hard work and results without gimmicks is what led us to pave the way for everyone in the Mitsubishi community. In recent years we have also proven to be a force in the GTR community, manufacturing and selling many great parts. Now combining forces with our new owner, Jimmy Bowling’s engine machine shop, we are adding unparalleled engine building and machining experience in the 4G63 and GTR communities and also expanding to other engine markets.
