Overview

The KPower K24A2 Ultimate Swap Package is designed to install a 2004–2008 Acura TSX engine into your 1990-2005 Mazda Miata (NA or NB chassis). This package includes an adapter plate, flywheel, engine mounts, tubular subframe, oil pan, intake manifold, coolant neck, and race header. It is built for reliability and performance, retaining OEM Miata steering geometry while reducing front-end weight.
Show original supplier description
The KPower K24A2 Ultimate Swap Package is engineered to facilitate the installation of a K24A2 or JDM K24A RBB engine into NA and NB Mazda Miatas, eliminating the complexity of sourcing individual swap components. This comprehensive package includes a K series to Miata transmission adapter plate, a lightweight K series to Miata flywheel, machined engine mounts with selectable poly or rubber pads, and a tubular subframe. It also features a baffled aluminum oil pan with a pickup tube, a machined K20 oil pump adapter housing, a KPower RWD intake manifold, a K24A2-specific upper coolant neck, a slim flywheel dust cover, a serpentine belt, and a stainless 4-2-1 race header. Buyers can choose between a 74mm cable throttle body assembly or a Bosch 74mm Drive-by-Wire throttle body assembly. Installation considerations include NA chassis hood clearance; the K24 engine is approximately 0.5 inches taller than a K20 and will not fit under a factory NA Miata hood without modification. A modified valve cover is recommended for proper clearance. The swap is compatible with right-hand-drive Miatas, but the header is excluded for RHD setups; custom solutions involving an RHD subframe are available by contacting KPower Industries directly. Engine compatibility for the mounts is specific: they are designed for JDM K24A RBB, K24A2, K24A3, K24A4, K20Z3, K20Z4, and K24A8 engines. They do NOT fit K20A2, K20Z1, or K24A1 blocks due to incompatible bolt-hole locations. All products are intended for off-road motorsports use only. Supporting parts, such as electronics packages (Haltech Elite 1500 or Link G4X), K24A2 OEM parts, and cooling system components, are recommended for a complete swap.
