What is a K-Swap?

A K-Swap is the process of installing a Honda K-Series engine (K20 or K24) into a vehicle that didn’t come with one from the factory. Most commonly done in 90s–2000s Hondas like the Civic EG/EK and Integra, but enthusiasts have successfully K-swapped almost everything — from MR2s to Porsches.
