Wild Ideas - Engineered to Perform

​

Concussion Garage was built around a simple idea: the wildest swaps in car culture deserve a real home. We started this brand because we’ve always been obsessed with the beautiful wrongness of pairing classic American lines with Japanese engineering—especially when that engineering starts with a 2JZ. To us, a pro-touring muscle car or a time attack monster with a 2JZ powertrain and an AWD drivetrain isn’t a bad idea — it’s the whole point. The kind of combination some people would dream up after a mild concussion is exactly what we’re here for: bold builds, unconventional thinking, and performance-first machines that challenge tradition and frustrate purists in all the right ways. The 2JZ has long been celebrated for its strength and tuning headroom, which is exactly why it became the foundation of our vision.

​

Our first build sets the tone. It’s a 1971 Plymouth Scamp — a 2JZ-swapped pro-touring machine that was originally configured with a Megasquirt ECU more than 14 years ago and is now being pushed into its final chapter with a fully built 1,200+ horsepower-capable 2JZ. It’s a Pacific Coast Highway cruiser backed by a fully built A340E automatic transmission, but it’s also designed to get serious when the road turns aggressive and conditions heat up, with a custom engineered liquid C02 cooling system for the liquid-air intercooler and a custom autocross suspension built by Bergman Auto Craft. It’s equal parts statement piece and engineering exercise, and it tells you everything you need to know about how we approach a build.

​

And we’re just getting started. While the Scamp is being wrapped up and wired for its final stages, another 2JZ is already in motion for an AWD 1973 Plymouth Duster. This one won’t be built for cruising — it’s being shaped into a time attack gremlin with its sights set on the Pikes Peak International Hill Climb, where cars take on one of the most demanding hill climbs in motorsport. If you want to see where this all is headed, check out the renderings on the site. Concussion Garage exists for the builds that shouldn’t work on paper, but absolutely do when they’re engineered the right way.

All of the product sold as part of Concussion Garage is to help bring awareness to our brand and is sold at cost. We want it to always remain affordable and different than what you would find elsewhere. Cool shit should always be accessible and never burn your wallet.
