Flyin Miata Stage 1 turbo system for 1990-93

Emissions legal everywhere in the US! CARB EO D-601-3. This is the only truly CARB legal forced induction option available for the 1.6.

Flyin' Miata turbo systems have been the standard for years. They offer easy installation of safe and clean power with proven durability. Our Stage 1 turbo system - once known as the Voodoo II - is ideal for someone looking for an easy installation, good horsepower, no emissions hassles and lots of upgrade potential (for dedicated track / not-street-legal cars). Expect approximately 160 hp at the rear wheels, compared to a stock 93 hp. This is limited by the size of the stock injectors.

The manifolds have just been redesigned after some CFD (computational fluid dynamics) testing. They now offer 24% greater flow than our previous design and are also nearly 4.5 lbs lighter. Combined with the new outlet, the manifold / turbo / outlet assembly is nearly 6 lbs lighter!  They have staggered runner diameters to ensure consistent timing of the exhaust pulses into the turbine. This means faster spool and the potential for higher power. Now Cerakoted! The manifold and outlet are both Cerakoted in C-7900 Glacier Titanium. It's rated for 1,800°F (980°C), so it's perfect for our application. We've been running this coating on our cars for over a year, and it's held up great through track days and daily driving. The new parts are a direct replacement for the old. Do you want even more info on our new manifolds and outlet? You're in luck! Check out our Knowledge Base article on them here.

The intercooler means that you will keep all of your horsepower no matter how hard you run your car. It's powder-coated for durability and good looks, but with a special thermal property that allows it to shed heat as well as bare aluminum. The FM logo on the intercooler can face forward (visible) or rearward (invisible).

All of our turbo kits use the same basic hardware. Every part has been designed taking performance, durability and installation ease into consideration. We don't believe there is a better (or more complete) turbo system available. With our kits, you won't be making extra trips to the hardware store for nuts and bolts; every part you need is included.

The Voodoo Box ekes as much power as possible out of the stock injectors without resorting to mechanical tricks such as high fuel pressure. There's no tuning and no need to install high-pressure fuel pumps or bother with fuel lines at all. The car simply makes smooth, effortless power without a fuss.

Fuel management is handled by our own Voodoo Box, which uses the stock injectors to deliver more fuel. Because it only modifies the signal under boost, the car acts completely stock at idle and cruise. Tuning is a quick and simple process. 1993 California cars have sequential (one at a time) fuel injection, whereas non-CA 1993 cars and all 1990-92 cars have batch (two at a time) fuel injection, be sure you choose the correct option. Check the underside of your hood to see what emissions your car has. 

The turbo is a GT2560R, which is a great match to the Miata engine at this boost level. It makes just as much boost down low as a smaller unit, but without choking off the top end. It's now attached to the manifold with our custom-made Inconel studs and Stage 8 fasteners - an upgrade from the stainless steel studs we used to use.

Along with this turbo system, you will need a new clutch. Cars that see track use or are in hot climates will also require a radiator upgrade.

The downpipe may or may not fit with your automatic transmission. We've seen mixed results. We cannot guarantee fitment with an automatic. You could also need a vacuum accumulator and there might be some idle issues - in short, while it can be made to work, prepare for a bit of a headache if you're installing this on an automatic car. 

Water supply note: if you are using an FM coolant reroute, you will need the connection kit for the reroute to take full advantage. 

Overall fitment note: The parts in this kit assume you have the original engine in the car. If your engine has been swapped for one from a different year, please contact our tech support department to ensure you get the correct parts.

Tools note: A 37/64" drill bit and 3/8" NPT tap are required for installing the oil drain and two M8x1.25 nuts are used as "tools" to install the turbo studs. If you do not already have these tools available to use, we have a separate tool kit available to purchase, Bag 2A, listed above.

Remember, all FM products come with full Lifetime Support to the original purchaser!
