This isn’t a show car. It’s a GET LAPS car.
In this episode of CARNATOMY, we break down Jeff Wasilko’s purpose-built NA Miata — a lightweight momentum monster designed to do one thing exceptionally well: make drivers faster.
Jeff is a race instructor, and this car is his classroom. Let’s take a walk around his NA Miata Build here from @LimeRockPark at @Gridlife Circuit Legends!
Under the hood sits a 2.4L Ecotec swap, delivering reliable, usable power in a perfectly balanced chassis. Supporting the drivetrain is a dialed-in suspension setup featuring Ohlins coilovers, tuned for maximum feedback and consistency lap after lap.
At each corner, the car rides on KONIG Hexaform wheels wrapped in sticky track-focused rubber — lightweight, strong, and built to handle abuse.
In this episode, we dive deep into:
- The full engine bay and Ecotec swap details
- Suspension geometry and Ohlins setup philosophy
- Wheel and tire package selection
- Aero choices that keep the car planted
- A stripped, functional cockpit designed for focus and driver development
This NA Miata isn’t about dyno numbers or parking lot points. It’s about seat time, consistency, and chasing faster laps — whether you’re a student or an instructor.
