All right, it’s another Miata. But who can blame us? For almost 20 years Mazda’s iconic little roadster has been the standard against which fun performance cars from around the world are measured. The Miata is ready to do the job in a variety of roles, from top-down touring to flat-out handling—heck, it even makes a decent commuter.

One thing the Miata doesn’t have, however, is an abundance of power. By some standards, they’re downright slow in a straight line.

We’ve tried a bunch of bolt-on speed parts on many Miatas through the years, often scoring the 10 or 20 additional horsepower needed to make the car a bit more fun. We can usually boost rear-wheel power from a little more than the stock hundred to somewhere near 120.

While this seems like plenty for a two-seat roadster in the 2200-pound range, we’ve never really reached the full limits of the chassis. We just had to find out what happens when a Miata goes one louder.

There are literally dozens of ways to apply forced induction to a Miata, and we figured that as long as we would be doing the job we should make sure the final result would suit our needs. The first step in that process was harder than it might seem—determining what our needs were.

In case you're wondering what happened to this car, it's gone through a few owners and it's still in the GRM family. My son bought it earlier this year and had it shipped up to Michigan. It's got 30,000 more miles on it and had been sitting after a few minor issues crept in. The sitting added a few more issues. So it's a project car again. We'll put up a build thread soon, but in the mean time here are some pictures of it.
