Ultimate K24 Miata Swap Package
Our Ultimate K24 Miata Swap Package is finally here!
This package is designed to install a 2004-2008 Acura TSX engine (K24A2) in your NA or NB Miata, and take the guesswork and parts hunting out of the equation. Plus you’ll save a few hundred dollars off the swap cost by purchasing everything all at once.
Most customers see 220+ whp and 180 wtq N/A from stock K24A2 engine swaps, with lots more N/A power potential from the K series platform.
Kits are usually in stock and ready to ship. If you'd like to confirm stock before ordering, email us at email@example.com.
With our KMiata engine swap package, we don't compromise performance. Specifically, our kit:
- Retains OEM Miata steering geometry

Doing a K24 swap in an NA? The K20 clears the stock hood, but a K24 is about a half inch too tall. If you don't want to cut your hood, we recommend this hood from our friends at Treasure Coast Miata. They made a street version with headlight cutouts, as well as the race version to deleted headlights.
Note: The engine mounts included in this kit are performance-oriented and designed to limit engine movement. The additional stiffness may result in a slight increase in NVH (noise, vibration, harshness), but can withstand years of hard driving as a result.
