Any good car enthusiast is well aware the benefits of an LS swap. Dropping one of General Motors’ compact, V8 pushrod motors into the front of a sports car is a relatively cheap and easy way to make huge amounts of power and get that desirable eight-cylinder soundtrack. They are extremely common for this reason, however – making them a bit unpopular among those who like to go against the mainstream.
One man who certainly isn’t mainstream is Rob Dahm. The popular YouTuber is a Mazda rotary engine evangelist and has built the spinning Dorito motors up to be extremely powerful in the past. Dahm recently outdid himself, flipping the LS swap narrative on its head by pulling the LS6 engine out of his C5 Corvette Z06 and dropping a two-rotor 13B rotary engine in its place.
The two-rotor engine he dropped in the C5 was actually sold to Dahm by Mazda USA, who made an exception for him and his ridiculous Corvette Z06 build and sold him a motor that would have been intended for a race team and not a consumer. He plans on bolting a turbocharger to the two-rotor engine and showing his YouTube following just how much power this rather unconventional engine design can make.
Mazda fans could see Dahm’s build as payback in a way. There are countless RX-7s out there with GM LS engines sitting in place of the rotary engine that originally came with the car, which rubs some RX fans the wrong way. Finally they will get to see a build that forgoes an LS in favor of a rotary – no matter how strange of an idea it may be.
You can see the beginning of Dahm’s wild rotary Corvette build in the video embedded above. We’ll be providing updates on the project as it comes along as well.
