What we do
Explore What We Offer
At Foji Raceworks, we’re Mazda MX-5 specialists with a passion for precision, performance, and restoration. We also bring our expertise to Japanese and BMW cars, tackling everything from general body welding repairs to full nut-and-bolt restorations.
Our services cover the full spectrum of performance and custom work, from engine servicing and tailored engine builds, to MX-5 turbo and engine conversions. Whether it’s a simple wheel change, a full bespoke modification package, or building a car to perfectly suit the driver, we’ve got it covered.
We also specialise in motorsport wiring, ECU installations, and safety device fitment such as roll cages, alongside bespoke motorsport fabrication, including exhausts, intakes, and manifolds. Every project is approached with meticulous attention to detail, motorsport-level expertise, and a focus on delivering a car that’s built to perform, safely and reliably.

Learn More Motorsport & Modification
From routine servicing, clutch replacements, and maintenance to full motorsport preparation, we cover every aspect of your car’s performance, including wheels, tyres, suspension setups, and brake upgrades.
We also offer power upgrades and performance modifications, from ECU tuning to full engine conversions and bespoke modification packages, all tailored to your driving goals, on the road or the track.

From CAD design to a fully finished component, we turn ideas into reality. We specialise in TIG welding, bespoke exhaust systems, custom manifolds (turbo and naturally aspirated), intake systems, and roll cage modification and installation, all built with your performance goals in mind.
Learn more → 03Restoration
Our restoration philosophy is simple: the finished result should look as though no one has ever worked on it, OEM or better in both appearance and longevity. We undertake everything from general body welding repairs to full nut-and-bolt restorations, always with a focus on quality and correctness.
Our services include arch, sill, and chassis repairs, full underbody restorations, and chassis strengthening or modifications. No restoration is too small, we tailor each project to suit your needs, goals, and budget, without compromising on standards.

What started as a hobby some ten years ago, building and tuning my own Mazda MX-5, quickly grew into a full-time passion. From learning TIG welding in a small unit to running our larger workshop today with a tight-knit team, we’ve developed the skills and equipment to take on any project.
Foji Raceworks now specialises in motorsport customisation, performance builds, and fabrication, alongside restoration, precision metal work, and engine conversions delivering quality, passion, and reliability for every car.
Let’s take a further look at who we are.
