• Swap an LS3 into your ND Miata with the Flyin' Miata ND DIY V8 kit

      Mazda Miatas have a reputation for being fun to drive with a great chassis but there is one glaring area of weakness. That area would be the motor and while the Miata is not designed to be a muscle car a bit of muscle certainly will not hurt.

      That muscle comes courtesy of a GM LS3 V8 and a Flyin' Miata DIY V8 swap kit.

      Imagine a Corvette carrying 1000 less pounds. Sounds fun, right?

      You can get the parts necessary here:

      Put an LS engine under your hood! This is a brand new factory subframe that's been modified by our techs for this purpose. No used parts here! Why did we use a factory subframe instead of a tubular one? Stiffness and strength. This is a very stiff, very well designed piece on which Mazda spent millions to design and manufacture. Tubular structures can be very light and strong but they can struggle with the odd load paths required with both an engine and suspension trying to deform them. Stamped sheet metal has a more organic shape with fewer point loads.

      The V8 subframe is designed to use factory GM motor mounts for maximum NVH control. It also has been modified to ditch the factory electric power steering and use a hydraulic unit. The weak factory sway bar mounts are also replaced with stronger relocated units. Sorry, they are not available in alternative configurations.

      Our oil pan offers superior oil control to production units - nobody has ever lost an engine while running one of our pans, even with hard track use and (shudder) journalists. In the ND, it is possible to use other oil pans such as the LS7 MAST unit, but we have not tried all of them.

      We strongly recommend the use of stock LS3 car intake manifolds due to tight packaging under the hood. We also recommend using a CTS-V style accessory drive - GM part 19370821.

      The completion kit includes related parts for the LS installation. The largest part of this is the plate that covers the hole in the firewall - it's primarily aesthetic, but it does give you a nice way to hide wiring. Also includes miscellaneous nuts and bolts.
      Sounds like a good time to us and makes for a hell of a sleeper and project.
