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. 

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.

With our KMiata engine swap package, we don't compromise performance. Specifically, our kit:

• Retains OEM Miata steering geometry
• Drops weight from the front of the vehicle
• Can handle all the road racing abuse you can give it

Doing a K24 swap in an NA? The K20 clears the stock hood, but a K24 is about a half inch too tall. Add one of our modified valve covers to your order to fit the K24 under your factory hood.

Note: The polyurethane engine mounts included in this kit are performance-oriented and designed to limit engine movement. The additional stiffness may result in an increase in NVH (noise, vibration, harshness), but can withstand years of hard driving as a result.
