Project Thunderbolt: Building A LS3 Powered Miata – Part 3

Project Thunderbolt a LS3 Powered Miata Episode 3

Tom’s Turbo Garage has started a new project building a LS3 powered Mazda Miata. In this episode Tom takes his 6.2 L LS376/525 crate engine and mounts it up to the new subframe. Tom included a nice side-by-side comparison of the stock Miata I4 next to the LS3 V8. I have included screen captures of them below.
