Upon first glance, you would NOT expect to see a Mitsubishi 4G63 4-cylinder motor tucked into this Mazda RX7’s engine bay…an LS motor maybe..but definitely not a 4 cylinder engine!

Who can blame the owner though? The 4G63 is a BADASS little motor! Taking 65 psi of boost like it’s breakfast, and slinging this lightweight Mazda down the track with EASE! We just wish we could have seen the E/Ts!
