{"product_id":"k24a2-ultimate-swap-package","title":"K24A2 Ultimate Swap Package","description":"The KPower K24A2 Ultimate Swap Package streamlines the process of swapping a K24A2 or JDM K24A RBB engine into your 1990-2005 Mazda Miata (NA\/NB). This comprehensive kit eliminates the need to source individual components, offering a bolt-on solution for enthusiasts seeking enhanced performance and reliability. The package includes a K-series to Miata transmission adapter plate, a lightweight flywheel, machined engine mounts with selectable poly or rubber pads, a tubular subframe, a baffled aluminum oil pan with a pickup tube, a K20 oil pump adapter housing, a KPower RWD intake manifold, a K24A2-specific upper coolant neck, a slim flywheel dust cover, a 1320mm serpentine belt, and a stainless 4-2-1 race header.\n\nCustomers can choose between a 74mm cable throttle body with an Acuity TPS or a Bosch 74mm Drive-by-Wire throttle body. The swap prioritizes OEM Miata steering geometry retention and reduces front-end weight, making it suitable for both street cars and track applications. Most customers report achieving over 220+ wheel horsepower and 180 wheel torque naturally aspirated with a stock K24A2 engine, with significant potential for further gains through bolt-ons and tuning.\n\nImportant fitment and installation considerations apply. The K24 engine sits approximately half an inch taller than the K20, requiring hood modification or the addition of a KPower modified valve cover for proper clearance on NA chassis. While compatible with right-hand-drive (RHD) Miatas, the included header is not compatible; RHD users should contact KPower for custom solutions. Furthermore, the engine mounts are designed to bolt to specific K-series engines: JDM K24A RBB, K24A2, K24A3, K24A4, K20Z3, K20Z4, and K24A8. They do NOT fit K20A2, K20Z1, or K24A1 blocks due to incompatible bolt-hole locations on the left side of the block. All products are intended for off-road motorsports use only, and users are responsible for adhering to local laws.","brand":"KPower","offers":[{"title":"Default Title","offer_id":52686550729016,"sku":"KM-ULTIMATE-K24A2-V3-R-C","price":6395.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687882134.webp?v=1784874814","url":"https:\/\/store.motormia.co\/products\/k24a2-ultimate-swap-package","provider":"MOTORMIA","version":"1.0","type":"link"}
