Quick. Think of the most un-original platform to build!
Chances are, you answered "MX-5" - and that's OK!
The Miata is an amazing platform with a huge amount of potential. Every modification and swap you could think of has been done to a Miata somewhere, some time. It is, in this regard, a RWD Civic.
Once the stock engine is in need of replacement, many owners opt to swap it for one that has a bit more punch. There are LS-swaps a-plenty, Honda K- and J-series swaps, SR20, 1JZ/2JZ, RB... There is even a Geo Metro i3 Miata running around!
So in this world of "it's been done before" - the word "unique" is tough to come by.
Luckily for me and my love of strange things, a local company shared my views and, years ago, devised an entire swap kit to power Miatas young and old with the most bland engine GM has ever produced. An engine so beige, most people don't even know its engine code:
At 2.4L, the LE5 EcoTec from GM has the power required to really sit inside anything and feel normal. That means they put it into everything imaginable:
Chevy Cobalt, Pontiac G5/G6, Saturn Sky, Saturn Ion, Chevy Malibu, Buick LaCrosse, etc...
And now, thanks to MT Motorsports, it sits in a Miata. Below is a vlog/montage video of the build!
(Will edit as soon as I figure out how to directly embed videos - thanks for understanding!)
