Our History

Engineering Excellence.
Born from 20 Years of Barra Mastery.

At Atomic Performance Products, we don’t believe an engine platform is ever truly "finished." Under the leadership of Nick Bucher and Next Engine, we are entering a new chapter defined by relentless evolution. We are taking 20 years of Barra excellence and subjecting every component to a modern audit—updating, refining, and strengthening our catalog for the next generation of builders. 📈

Our philosophy is rooted in Continuous Improvement. By working across the entire spectrum—from high-street builds to world-class race teams—we gain the real-world data needed to engineer parts that work in any combination. We don’t just supply the market; we push it forward by re-engineering the very foundation of performance. 🛠️

Engineering the Foundation

We led the way with the industry-first aftermarket cast Barra block, proving that when factory limits are reached, we build a better starting point. This same engineering rigor—utilizing advanced CAD/CAM modeling and FEA testing—is applied to every bolt, pump, and rod we sell to ensure they survive the 2000hp+ frontier. 🧱

A Proven Engine Architecture

Our engine program is the heartbeat of the brand. We offer a validated progression from the street-refined 475 ST to the track-dominating GT-R Unlimited. Each unit is blueprinted and test-run in-house to ensure the "Atomic Standard" is met before it ever reaches your garage. 🏁

Integrity in Support

A performance build is a journey, and we are your partners in it. We pride ourselves on expert technical support and a fair, transparent warranty. We stand behind our workmanship because we know the science and sweat that goes into every Atomic build. 🤝
