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.
Those crazy Swedes! I don’t think I’ve ever featured a build from the Nordic region that hasn’t been absolutely bonkers. This time it’s a Volvo 142 that has received a hand built custom chassis beneath a gutted floor pan, with a minor engine upgrade to go with it. Wait, did I say ‘minor’? I meant to say ‘completely custom designed and machined quad-rotor 26B’. The pictures speak for themselves.
Thanks to Tony from Mooseville Performance (the owner/builder) and also reader Matthias for submitting on separate occasions.
So, the last RX7 I posted was devoid of a rotary engine, so here’s another one that keeps it’s Wankel roots, but with a twist. If you love engineering, machining, welding, lathes, heat treatments, stress analysis, and 3D renders, then you’re going to love this completely custom made 4-rotor powerplant. Definitely one for the tech-heads amongst us.
