Chevy Colorado Race Truck With a Boosted GM I6 Just Feels Right

These turbocharged Atlas 4200 swaps are picking up steam, and seeing how well it works here, it's easy to understand why.

It’s already well-established what a V8 can do in a tiny(ish) truck. What really gets my blood pumpin’ is something like this Atlas I6-swapped Chevy Colorado. Rather than opting for an LS, the guy behind the Reignited – Cycle and Automotive YouTube channel tossed in a GM 2JZ with a big ol’ turbo. He’s been working on it for a few months, and now, it’s a running race truck that’s sure to go fast.

The project started when the host, Sky Perry, bought a $1,200 Colorado with a blown engine. Although he’s been known to swap in a Hemi or two in the past, like with his twincharged 392 Dodge Magnum, he scored a cheap Atlas 4.2-liter I6 out of a $300 Chevy Trailblazer. It was a budget build all along, and according to the latest update, he’s in it roughly $7,800—and that’s including the truck.

Of course, that number would be way higher if he hadn’t done all the work himself. Perry estimates that he spent 250 hours getting the Colorado on the road, fabbing a custom exhaust manifold for the VS Racing turbo as well as tuning it with a MaxxECU, swapping in an 8.8-inch rear-end, dropping the suspension 3 inches, and all the smaller jobs. Impressively, it’s still running the factory Colorado AR5 manual transmission, though that required a custom-machined flywheel as the Atlas was never offered with this gearbox. He finished it off with a $100 clutch (yes, really) and the truck was ready to roll.

Perry had help on his Colorado race truck from Calvin Nelson (Nivlac57 on YouTube), whose work I’ve written about before. He’s the one who swapped a 1,000-horsepower Atlas 4200—or “AmeriBarra,” as he likes to call it—into a fifth-gen Camaro. Not only that, but he also boosted an Atlas I6 Chevy Trailblazer to a 10-second quarter-mile. There’s a community developing for these swaps, and you know, I’m not sad about it.

Perry posted a video update over the weekend that shows the truck making 426 wheel horsepower and 413 lb-ft of torque on the dyno. That’s seriously impressive, and what’s more, it only took 10 psi of boost to hit those numbers. It’s one heck of a rig that “makes all the right noises,” as Perry told me over email. I bet!
