Putting a big engine in a lightweight sports car is a time-honored hot rodding trick. That's exactly what Tom Tharp of Tom's Turbo Garage did by stuffing one of these Project Thunderbolt LS engine and drivetrain combos into a 2004 Mazdaspeed Miata. The packages feature a Chevrolet Performance 525 hp LS3 engine—typically backed up with a T56 Magnum 6-speed transmission (available separately). In this part of the build, Tom sourced the Chevrolet Performance accessory drive, engine controller, transmission install kit, and parts from Moroso, Hurst, Innovate, and ACDelco from Summit Racing.

Project Thunderbolt LS Miata engine and drivetrain combos include:

* Chevrolet Performance LS376/525 crate engine
* Chevrolet Performance CTS-V accessory drive kit
* Chevrolet Performance engine controller kit
* Chevrolet Performance T56 transmission installation kit
* Hurst Billet Plus high performance shifter
* ACDelco starter
* Chevrolet Corvette LS3 fuel rail covers
* Moroso universal air/oil separator
* Innovate MTX-L digital air/fuel gauge
* Thermo-Tec starter heat shield

How It Works

Your support of the Thunderbolt conversion goes beyond a radical power mod. It teaches people like me how their cars can far above and beyond stock. I sincerely hope you continue to support documentaries that teach new enthusiasts to explore the limits of what our cars can be. Loved It!
