Earlier this year, Callaway debuted its new supercharged upgrade package for the Chevrolet Colorado ZR2. This was a welcome addition to the Callaway lineup, as the Colorado ZR2 leaves a bit to be desired in the powertrain department, with its 3.6L LGZ V6 producing a rather tame 308 horsepower and 275 pound-feet of torque.
Now, Callaway has produced a video giving us a more in-depth look at its blown Colorado ZR2. The custom truck features a TVS1740 supercharger system, along with a Callaway Dual Pass intercooler system, Callaway high-flow intake and Callaway sport exhaust, raising its output to a healthy 410 horsepower and 400 pound-feet of torque. Chevrolet may not offer the Colorado ZR2 with a Small Block, but with this upgrade kit, the truck is essentially producing V8 power.
Some small cosmetic upgrades are also included in this upgraded package, including Callaway exterior and interior badges, all-weather floor mats, Callaway-branded key fobs, an underhood engine build plaque and a certificate of authenticity.
As we noted in our previous article, the best part of the Callaway SC410 Colorado ZR2 is that it can be ordered directly from Chevrolet dealers. Additionally, the kit does not void the factory GM warranty and comes with a three-year, 36,000-mile warranty on all Callaway-installed parts. A transferable five-year, 50,000-mile warranty is also available for extra. Oh yeah, the truck can be serviced at any Chevrolet dealership as well, so owners don’t have to worry about calling the Connecticut-based if the engine starts to act up.
“Equipped with Callaway’s intercooled, TVS1740-based supercharger, high-flow intake and exhaust systems, and precise electronic powertrain management calibration, Callaway Colorados deliver significant increases in horsepower and torque,” the company said following the truck’s unveiling in February. “That means improved acceleration, towing and hauling.”

One of the things not mentioned in this article is that the price for the supercharged engine transplant is about $15K, the price of a small block 6.2L V8 crate motor is about half that price meaning it would theoretically cheaper for Chevrolet to build Colorado ZR2 trucks with a V8 than a supercharged 3.6L V6.
But then you have to add in the cost engineering the swap. The cost of the changes required to pass the crash standards, the cost of the crash testing, the cost of the emissions testing, the cost of the CAFE testing,
Then you have to toss this all out when the new truck arrives next year as they plan to move on.
The consumers also would likely pay added CAFE fee for even lower MPG averages.
Then you figure less than 5% of production would be realized.
There is more. You would have to change the transmission too. The one in the truck is for the V6 and is not the heavier V8 8 speed unit.
While it would be an economical crate engine swap there is so many things a company would be required to do.
Simple swaps are not just simple swaps anymore.
Even something as simple as the changes to the Bison were millions of dollars. Just the new close off panels under the head lights was several million in tooling. That is not including crash testing. They kept the stock size wheels and engine to avoid added cost of emissions and Cafe certifications that would even more cost.
Government regulations have relegated these low volume models to these tuner pretty much anymore. That is why there is so many and why GM supports them.
Did you bother to think he meant buy a regular ZR2 and get a crate engine to put in the truck instead? Of course GM wouldn’t go through all that lol.
Even doing this by yourself and getting appropriate GM parts in the truck would still be cheaper. Plus most likely can be serviced at the dealership on top of it.
Did you bother to read his last sentence.
“ meaning it would theoretically cheaper for Chevrolet to build Colorado ZR2 trucks with a V8 than a supercharged 3.6L V6.”
Based on this comment Saying GM building this means GM building this….
Yes it would be cheaper if some one did this themselves. It would be even cheaper to do a Edelbrock supercharger yourself.
And dealer involvement into working on I t may vary due to the quality of the install. They generally will no take a balled up mess that was unsafe they would not touch it.
