Only from Flyin' Miata. Nobody else in the world can do this.
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.
Fits all ND Miatas. As far as we know, it should also fit the Fiat 124 but we have not tested this yet.
