The Workshop
About Magnum
A genuine obsession with Japanese performance, backed by an engineer's discipline for doing things properly.

We don't just work on cars. We perfect them.
Magnum Performance was founded on a simple belief: that the JDM legends deserve to be built and maintained by people who truly understand them. From the Golden Era icons to the modern greats, Japanese performance is all we do.
Led by Darren Robinson, our Enfield workshop combines the soul of Japanese performance with the science of tuning — delivering custom builds, track-ready setups and meticulous servicing for the Toyota Supra and Nissan Skyline, from the 2JZ and RB legends to the modern GT-R.
Whatever the project, every car leaves engineered for power, reliability and longevity — on the street and the track alike.
