My ULTIMATE Miata Build - Pt.1
DraftMazda NA · Built by Kostas · youtube
Build Overview
Kostas is on a mission to redefine what the iconic NA Miata can be, and this first chapter of his ultimate build makes an emphatic statement. At the heart of the transformation is a full LFX 3.6L V6 engine swap — a dramatic departure from the Miata's traditional four-cylinder roots — breathing life into a chassis that was never meant to carry this kind of firepower.
With 285 horsepower and 216 lb-ft of torque pushing a notoriously lightweight platform, the performance numbers tell a compelling story. A 0-60 sprint of 4.8 seconds and a quarter-mile pass at 13.2 seconds place this NA Miata firmly in sports car territory, while a top speed of 145 mph underscores just how serious this build has become. Dedicated LFX swap-specific exhaust and header kits ensure the drivetrain package is cohesive and purpose-built rather than cobbled together.
To keep the added power in check, Kostas paired the engine work with an upgraded cooling system — including a new radiator and revised coolant plumbing — addressing the thermal demands that a V6 conversion naturally introduces. Complementing the powertrain work, a comprehensive suspension overhaul featuring new springs, dampers, and bushings brings the chassis dynamics up to a level worthy of the power on tap. With a build score of 8.2, this is only Part 1, and the foundation laid here suggests something truly special is still taking shape.
Owner Insights
Kostas reflects that the car grew far beyond its original intent through incremental steps, and that taking it fully apart — something that had never been done properly — was the only way to truly finish what was started. His takeaway is that a project car needs a definitive reset moment to realise its full potential.
