A 20B-powered Mazda R100 at SEMA – Video

By Kian Heagney, 31 Oct 2018 Show 'N' Shine

SEMA is always a good place to start if you want to find cars modified in ways you’ve never seen or even thought of before, and it only took Telfo a few days to find a little Mazda that proves the theory works.

This particular animal is a Mazda R100 all the way from Vancouver, Canada. Rod from Hot Rod Resto’s built the car in his shop from the ground up, with the key centrepiece of the build being the 20B rotary engine sporting a big single turbo. Rod found the car 11 years ago, and before the build started the car was actually partly used a doner car for one of Rob’s mates R100’s, donating the firewall and the belly before Rod began cutting the it up to get it ready for time attack duties.  The car needed to be cut anyway to fit the T56 ‘box, the fit is so tight inside that the trans is left exposed with no tunnel between it and the driver!

The custom rear wheels are so big that two – yes, TWO – tyres are used per wheel to give the car the massive footprint on the road while still keeping rotating mass and diameter down. The wheels have their own story all together. They’re custom made for the car and have a Wilwood wide-five bolt pattern with full floating hubs, giving Rod the peace of mind that they’ll take any punishment that comes their way on the track.

The car hasn’t made it to the track just yet, Rod plans to take it for its first outing at Area 27 Motorsports Park in Canada, a track only recently completed that’s designed by racing drivers to use the natural terrain of the area.

“You should give a little respect when a little rotary car pulls up next to you, because odds are it’s going to make you look dumb,“ he said.
