One of my favourite cars we've featured over the last year is the twin-turbo 1MZ-powered SW20 MR2 owned and built by Tristan Hewitt from WTFAuto published in Zoom 137. I like the use of the 'Camry' V6 engine conversion as a big single-finger salute to the purists.
Specifications of the build are as follows:
