Earlier this year, we shared a video of YouTuber Rob Dahm working on his rotary-swapped Chevrolet Corvette C5. Dahm’s rotary Corvette was inspired by the droves of General Motors LS-swapped Mazda RX-7s that have been built over the years, as Dahm is a fan of the Wankel motor and doesn’t like seeing them ripped out in favor of something that he finds to be less interesting.
We recently stumbled across an LS-swapped FD Mazda RX-7 for sale on Race Cars Direct, and while Rotary purists usually hate this sort of build, it would be hard for any car enthusiast not to appreciate this high-quality, self-built race car.
According to the listing, this FD Mazda RX-7 was developed over the last 12 years, with the owner starting out with a rust-free, 1992 RX-7 shell. Today it has a full race-spec roll cage, a wide body conversion with custom body panels and a ton of other motorsport hardware including BBS center lock wheels shod in Avon slicks, two-way adjustable dampers and full AP Racing brakes with six-piston front calipers and four-piston rear calipers.
The powertrain is where things really get interesting, however. For 2019, the owner dropped in a new 7.0-liter LS7 built by Mast Motorsports, which is good for 590 horsepower and 500 pound-feet at the rear wheels. A Quaife 69G sequential gearbox with pneumatic paddleshifters, a carbon fiber propshaft, Ford Racing rear end gears, a billet lightweight flywheel and a twin-plate clutch complete the package. This car also weighs just 1,104 kgs, the seller says, equivalent to 2,433 lbs.
This listing will be of interest to any of our readers located in the United Kingdom or Europe, as the seller and car are in Great Britain. If you’re only interested in the Mast Motorsports LS7 and Quaife racing gearbox, the seller will part with the powertrain and body separately. That means this FD Mazda RX-7 body can still have a Rotary dropped back into it, if you just so happen to be among the contingent that feels as though a Rotary being replaced by an LS is sacrilege.
