We've done it again! Another all-in, complete engine swap package for the K series, this time for the popular NC chassis (2006-2015 Mazda MX5, manual transmission only).
Thanks to the NC chassis coming from the factory with an four cylinder with the exhaust ports on the right side of the engine bay, the packaging on this K24 swap is the cleanest yet! Learn more about what makes this swap so special and refined in our blog post here. This swap retains the factory transmission and power steering system for an OEM level of refinement, with an optional A/C upgrade and more.
This package provides all aftermarket parts for a complete K24A2 conversion in your vehicle, including all of the required electronics. Just add an engine, some OEM parts, some assembly time, and your NC will be transformed into the car it should have been from the factory.
At this time, we are not accepting any omissions or substitutions in this package aside from the drop-down menu options. If you’d like to build your own kit to meet your needs better, please check out our smaller NC packages, as well as individual parts listed on our site.
Lead times for shipment vary, always reference our Current Lead Times page for up to date timeline for order fulfillment.

Important Notes:
All products are designed for off-road motorsports use only. Users are responsible for complying with all local laws in their county, state, and country.
Our engine wiring harness is designed for 2004-2008 K24A sensors, including the crank sensor, knock sensor, and injectors. The A/C compressor connector is for a factory NC unit.
If you plan on using injectors other than OEM K24A injectors, please specify at checkout and we’ll swap in the appropriate injector sub-harness free of charge. If you opt for injectors from our Fuel Delivery Collection, just add a note that you want a matching connector!
These engine mounts fit the following engine blocks: K24A2, K24A3, K24A4, K24A8, K20Z3 and the JDM K24A. They do NOT fit K20A2, K20Z1, or K24A1 blocks due to incompatible bolt-hole locations on the left side of the block. Please make sure you source the correct block for your project.
