Miata Turbo Forum - Boost cars, acquire cats. - FS: 300 whp

Located in Central Florida (Merritt Island) - $12k

1993 chassis with 198k miles
2003 UK powertrain. 70k original miles, 8k miles since engine rebuild

Moving and need to downsize the fleet. Never thought I would sell the Miata, but it's for the best...

I have owned this car a little over 6 years. I originally bought it in Los Angeles in 2016, where it had been since new. I shipped it to Massachusetts, where it was stored in an insulated garage until being shipped to Florida in 2017. After arriving in Forida, it was used as a daily driver and incrementally upgraded until early 2019. It was then taken off the road for a year-long build, outlined below.

The goal was a fully-furnished and reliable street car with a top-of-the-line powertrain (it's a shameless copy of TheCarPassionChannel's build). The car currently makes 300 wheel horsepower at 12psi on 93 octane. The bottom end can handle 500 whp, though the current turbo would limit it to ~425. This power level would require E85, and the fuel system is built for it, though the Miata 6 speed would have to be swapped for Getrag or ZF transmission. Car was tuned by Jeff Linfert.

The car is driven whenever the forecast is rain-free and has never let me down, whether that is short drives around town or hours of joyriding.
