This site gathers practical LS-swap information for the Hyundai Genesis Coupe (BK1 and BK2). Content is drawn from long-running community notes and public discussion on Reddit and Facebook. Not every tip applies to every year or engine — verify against your car and service manuals.
Before you begin: join the Facebook groups Swapped GCs and Genesis Coupe LS Swaps. Prefer Corvette accessory spacing on BK1 for radiator clearance; BK2 has about 1.5" more room. Plan a serious radiator/fan setup and an oil cooler early.
