Imported Hyundai engines, compression tested

Looking for a replacement Hyundai engine that has actually been checked? Every Hyundai motor we stock is imported and compression tested before it hits our shelves. We know a tired or knocking engine can sideline a good Sonata, Santa Fe or Elantra, so we only list clean, low-mileage long blocks that pass our inspection. Whether you need a Theta II 2.4 or a Gamma turbo, a tested replacement gets your Hyundai running again with a lot less guesswork.

Shop by engine (Theta II, Gamma, Nu)

We carry the Hyundai four-cylinders owners search for most:

• G4KJ (Theta II 2.4 GDI) – Sonata, Santa Fe, Tucson
• G4KH (Theta II 2.0 Turbo GDI) – Sonata, Santa Fe
• G4FJ (Gamma II 1.6 Turbo GDI) – Elantra, Kona, Tucson, Veloster
• G4NB (Nu 1.8) / G4NC (Nu 2.0 GDI) – Elantra, Tucson
• G4FD (Gamma 1.6 GDI) – Accent, Veloster

Every listing shows the engine code, year range and the model it fits, with clear photos. See our active inventory for current stock.

Which Hyundai engine do you need?

The correct engine matches your model, year and code exactly, since Hyundai used several closely related families. Most 2.4L Sonata, Santa Fe and Tucson builds run the G4KJ Theta II, while smaller cars like the Elantra, Accent and Veloster use the Gamma and Nu families. Not sure which code your car uses? Send us your VIN or the code off your old engine and we will confirm the correct match before you buy.

Fitment & compatibility

• Match the engine code exactly to your model and year
• Confirm turbo vs non-turbo and GDI vs MPI before ordering
• Many accessories transfer from your original engine  check each listing
• Hyundai and Kia share these engine families, so cross-reference if needed
