Garrett GT – 23.7X12X3.8

This specific core is rated for 1000HP. It is a top-tier choice for builds requiring four-digit power numbers while maintaining reasonable packaging dimensions.

Yes, this core is widely recognized as Garrett Part Number 486827-6002. It is a genuine, high-performance unit used globally in professional racing applications.

The 3.8-inch thickness offers a unique sweet spot. It provides significantly more cooling volume than a 3.5-inch core without the fitment difficulties often associated with full 4.5-inch or 5-inch thick units.

The 23.7-inch measurement is the precise manufacturing specification for the core's hot flow length. For fabrication purposes, it fits effectively into the same spaces as a nominal 24-inch core.

Yes, despite its 1000HP capability, the Bar and Plate design remains efficient at lower speeds. Its robust construction also resists road debris damage better than lighter racing cores.
