Turbo Miata vs. Turbo Miata! (Car Passion vs. Danny Courtney)

This was a texbook race showing that there’s a lot more to a turbo setup than just “PSI.” More displacement, a more efficient & responsive turbo, fuel that can handle more ignition advance, longer gearing, and flatshift were on my side. Here’s a brief rundown of the setups!

The Transmission Destroyer… TWO 6-speeds in two weeks 🙁
