Project Overview

Check out these go-karts on steroids! This pair of 2025 Stalker Kit Cars came to KTR Performance from a longtime customer and his friend—two local enthusiasts who share a passion for lightweight, LS-powered track machines. Both cars were built side by side, receiving nearly identical treatment to make them street legal, safe, and tuned for maximum fun.

Street Prep & Power Refinement

Each Stalker arrived as a custom-built LS3-powered autocross car weighing in at just 1,600 lbs—the kind of power-to-weight ratio that makes driving one feel absolutely wild. To prepare them for street use, we wired in turn signals, a horn, push-button start, and all the required safety indicators.

From there, we fabricated custom intake piping, upgraded the fuel supply system, and finished everything off with calibration on our Mainline Hub Dyno. Each car now puts down 341 HP and 320 FtLb, which in something this light translates to instant throttle response and serious acceleration. What a blast to drive!
