We've done it again! Another all-in, complete engine swap package for the K series, this time for the popular Right Hand Drive 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.

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 RHD 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 the factory Honda AC compressor on the intake manifold side of the engine.
• 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.
• For the right hand drive car owners using a JDM K24A RBB engine (the engine we recommend for any K24 swap project), here is some helpful information for a RHD NC Swap. Each part number listed is found in the UK market:
  • We do not offer an AC package for this swap.  You will need a K series AC compressor (P/N HS-110R) and then connect the signal wire to our RHD NC engine harness.  You will need custom AC lines made, which any AC shop can make for you cost effectively.
  • We do not offer a heater core hose kit for this swap, however you can use this list of parts to make it all work:
    • One 90 degree 16mm bend hose
    • One 135 degree 16mm bend hose
    • 1 meter length of 16mm silicone hose
    • Two 16mm hose unions
    • Eight hose clamps
  • Honda J35 flywheel bolts are required for the swap and included with our NC OEM Parts Package, or you can buy them separately. The Genuine Honda J35 bolts are unavailable in the UK market.
  • A UKDM water pump housing is required for our NC Power Steering kit to work, look for 19410-PNA-000 from a 2001-2006 CRV 2.0L MK2. Use the following hardware to attach the housing to the engine:
    • Two flanged M10x100 1.25 bolts
    • Two flanged M10x70 1.25  bolts
  • A UKDM water pump is required, look for Quinton Hazel P/N QCP3531. Use the following hardware to attach the water pump to the housing:
    • 6 flanged M6x30 1.00 bolts
  • A UKDM alternator is needed, look for Bosch 0986082800-907. Use the following hardware to attach the alternator to the housing:
    • Two flanged M8x50 1.25 bolts
    • One flanged M8x100 1.25 bolt
  • A UKDM Thermostat is needed, look for 19301-PNA-003 which can be found for 01-06 CRV 2.0L and 2.4L
