EcotecMiata Non-Mazda Transmission Swap Kit

Kits are custom built to order. Not refundable once ordered.


Please allow at least 8 weeks for delivery.


This kit is aimed at the conversion which won't be using a Mazda Miata transmission. Generally this is done when you plan to make more power than the Miata transmission will handle. This is especially useful for the 2.0L supercharged or turbocharged Ecotecs.

Kit includes the following individual components:
- Oil Pan kit
- Engine Mount kit

- Cooling Hose kit


Optionally you can choose to add our GM Clutch Hydraulics and/or AR5 PPF Mount 


The Clutch Hydraulics kit includes:
- Wilwood integrated reservoir master cylinder

- Aluminum mounting flange for master cylinder

- Braided stainless steel clutch hydraulic hose

- Special Adapter fitting to suit AR5 slave cylinder


The AR5 PPF Mount allows you to mount a 2008+ Solstice/Sky AR5 transmission to the Miata PPF, eliminating the need for a transmission crossmember. It does not include a driveshaft.


This kit does not include any of the fasteners to mount the transmission to the engine, nor does it include any flywheel, clutch or slave cylinder. It also does not include our air intake kit as most people using this swap kit will be forced induction.

*Does not include engine
