About This Site

LS-swapping a Hyundai Genesis Coupe has always been possible — but the knowledge lived in Facebook threads, partial Reddit write-ups, and personal Google Docs. This site pulls that practical information into one place so the next person does not have to dig as hard.

The core technical notes come from a community guide that has been refined over real builds (Holley Terminator X, wiring, cooling, power steering, driveshaft, and more), combined with public discussion on Reddit's r/genesiscoupe and the major Facebook swap groups.

Guides are free. Featured build pages help cover domain and hosting costs. Nothing here is affiliated with Hyundai or GM.
