20B-powered Time Attack NC MX5

Time Attack season is almost upon us, with World Time Attack Challenge just around the corner (click here for my photos from 2010), I thought it would be a great time to share this long-term build from Australia. The brainchild of a Mazda aficionado and die-hard collector, this NC MX5 welcomes the addition of firstly a supercharged Renesis 13B, and then a 20B 3-rotor with individual throttle bodies and a whole host of goodies. Apart from all the CAD screenshots, machined metal goodness, fabrication, welding and general race-car building, you’ll also find a bonus R35 GTR build and a visit to Mazda HQ in Hiroshima within the thread.
