WHY WE BUILD
THE KA
Most shops overlook the KA24DE. We built our reputation on it. It's affordable, abundant, and with the right hands — genuinely fast. We've forgotten more about this engine than most shops will ever know.
Parts Availability
Aftermarket support for the KA24DE has never been better. Forged internals, cams, heads, and turbo kits are all readily available — keeping build costs competitive without sacrificing quality.
Proven Platform
The KA24DE has been a staple of the drift and time attack scene for decades. It's been proven at every level of motorsport — from grassroots events to pro drift. We know exactly what it takes to make one last.
