Speed Academy created a two-part series on swapping a K20A into a Acura Integra. Although the guide was written around a K20A and a 1992 Integra, it should be helpful for those looking to use either a K24 as well as Civic. The series is more of an overview and doesn’t go into a step-by-step detail. I have outlined each series below.
Part 1 – K20/K24 in Civic/Prelude Swap Guide: This part goes over part selection and options.
Part 2 – K20/K24 in Civic/Prelude Swap Guide: This part goes over the installation of the engine and components.
Speed Academy has a video showing a 1992 Integra GS-R taking on some Porsche and Ferrari drivers at Streets of Willow. The car has a K20A2 inline-four with Kelford STG 1 camshafts and Mfactory LSD and a set of Nitto NT01 tires.
