Custom turbo systems, flawless welds, and dyno-proven tuning—engineered by Spoolin Industries to unleash your ride.
At the heart of Spoolin Industries are two hands-on operators who don’t just lead — they build.
Mathew Johnson, founder of Spoolin Industries, is a master fabricator known for his precision welds, custom turbo systems, and relentless pursuit of automotive perfection. If it’s metal, he can bend it, weld it, and make it boost-ready.
Simon, the man behind Tuned by Chop, is the tuning brains of the operation — specializing in ECU calibration, dyno refinement, and squeezing every ounce of performance from each build. His calm, calculated approach brings balance to the heat of the workshop.
Together, they form a powerhouse duo: one fabricates the firepower, the other dials it in.
Whether you're chasing big horsepower, street reliability, or a fully custom build — this is the team that makes it happen.

We handle everything from custom piping, intercooler setups, and exhaust systems to full chassis modifications, roll cages, and structural reinforcements. If it’s metal and it moves, we can build it.
Yes to both. We can fabricate completely new components to suit your project or modify and improve your existing parts for better fit, strength, or performance.
Definitely — most jobs require a booking due to high demand. Reach out with what you need, and we’ll line up a time that suits your build schedule.
It depends on the scope. Small jobs might be done within a few days, while full builds or complex setups can take a few weeks. We’ll give you a realistic timeframe upfront.
Absolutely. Whether you've got parts in-hand or a rough sketch of what you’re chasing, we can work with your materials and ideas to bring them to life.
We fabricate to high standards and can meet motorsport requirements. If certification is needed, let us know during booking and we’ll ensure everything complies with the relevant specs.
