With great power comes the need for great amounts of fuel. It's just the way things work. Above 300 hp, your stock pump just can't deliver enough fuel to feed the beast. So we've packaged our Big Fuel kit to include a new fuel pressure regulator, a high flow and high pressure pump and our FM fuel rail.

None of these parts are new, but we wanted you to know you could buy our manifold, turbine outlet and downpipe as a good starting point for a roll-your-own turbo kit.

They're lighter than stock - approximately 3 lbs per corner. They're stronger than stock. They allow for more range of suspension adjustment. They come with polyurethane bushings and low-friction ball joints. Awesome.

The Miata cooling system got a bit messed up when Mazda installed the engine in the Miata. Fix it with this re-route kit and improve your cooling overall as well as making it more even across the cylinders.

We need a lot of battery to start a V8 Miata. This is what we use.

We've added some multi-cellular polyurethane bumpstops to our suspension section. These give more suspension travel, a smoother ride and more consistent handling for all Miatas, but especially the 1990-97 models. In fact, we think they're such an improvement that we're now including them in all of our 1990-97 suspension kits.

Remember the Revlight? It was a nice little LED tach, but supplies dried up pretty fast. Well, this is the Son of Revlight - and it's a better piece. Easier to program, better dimming, a more solid case and some extra tricks like battery voltage indication. Best yet, it's fully available! Keith has one in every one of his cars, he thinks you should too.

It's not a new product. But it's been pointed out that we never put it on the website! So for all you homebrew builders, here's your manifold. Available with or without ceramic coating.

We've been working on our new clutches for over a year, and they're finally here. The holding power of an ACT Heavy Duty or Extreme, but with a pedal that feels like a stock clutch. It's all Keith will put in his cars.

It's not an exotic part, or a complex one, or an expensive one. But if you want a simple and easy way to disconnect your battery without tools, here you go. Perfect for when your Miata takes a winter nap or when you want to work near the starter.

A few years ago, a set of polyurethane suspension bushings cost $549. Now, a more complete set will set you back only $295! Okay, they're not a cool purple color anymore, but that's progress.
We now have a full range of bushings for the Miata. The only rubber you'll need in your suspension will be the tires!
Bushings galore

Finally, forced induction for the 2006 and later cars. And forced induction done right - a cast intake manifold, integrated water/air intercooler and OBD-II compliant engine management.

Did you know that pedals can be a performance part? Our pedal covers not only extend the gas pedal for easier heel and toe rev-matching, they also offer more traction than the stock rubber. No more slippery feet!

FM now offers full 3" exhaust systems. We have them for any turbo 1999-05 Miata as well as one for FM turbo cars that include a new 3" downpipe. Instant horsepower and spoolup!

You know you want it. GM's legendary LS engine stuffed under the hood of a Miata. No loss in ground clearance, less than 200 lbs weight gain (1/3 of which is on the rear wheels) and that noise. Every Miata should have 300 lb/ft of torque just off idle.
Yes, we'll do turn-key cars.
