No..not easy.

Why would you want Mazda wheels anyway ( )

Because they are very similar to the 4x114.3, you'd need custom hubs which are expensive.

Put simply, forget it.

Best bet would be look to convert to 5x114.3, so you can fit many wheels from bigger cars, like 200SX, skyline, late model 180sx, Commodore, Falcon etc.

That also involves a lot of thought, and replacement hubs. The rear is easy to convert, but the front is quite a bit harder.
