The machine shop at SpecJ is the core of our business. We pride ourselves on our state-of-the-art facilities and modern techniques.
About us
SpecJ Motorsport is a performance engine preparation facility, catering for everything from fast road to race engine building, machining, parts and more.
With 15 years of engine building/machining experience whilst working in other performance shops, a lack of performance orientated machine shops in the northeast was discovered. SpecJ was founded in 2021 by Jonny, with a vision to bring a one-stop-shop for all aspects of engine machining and building for the public and other shops alike. In this short space of time we have gained a reputation for working to close tolerances and producing products for the end user to the highest standards.
