This product has been retired. We are leaving this page here for reference. We now only offer emissions-legal turbo systems, such as our Stage 1.
The FM II is a legend in the Miata performance world, and this is the latest and most powerful version. Expect approximately 265 hp at the rear wheels at 12 psi, compared to a stock 110 hp. Driveability is excellent and there's no need to even remove the valve cover. Expect years of reliable high performance with this system. More power is available on built engines.
All of our turbo kits use the same basic hardware for super easy upgradeability. 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.
Fuel management is handled by the the FM221. This gives you full control over every parameter of your engine, right down to individual injectors. A laptop is required for programming, although every ECU is pre-programmed before it leaves Flyin' Miata. 550cc Deatschwerks injectors are included along with an integrated wideband O2 sensor, knock sensor and air intake temperature sensor. Since the fuel pressure is not changed, a fuel pump upgrade is not necessary.
For more information on the ECU, please see the individual writeup: FM221.
The standard turbocharger is the GT2560R. This is our favorite all-around turbo, providing good power potential with good spoolup. While a larger GT3071R is available, you really need upgraded engine internals to take full advantage. A smaller GT2554R is also available for those who make response their highest priority.
The kit is also available without a turbocharger for those who want to substitute a different size or use one from a different source. If you choose to configure the kit that way, you will have to find a turbo.
Along with this turbo, you will need a new clutch. Cars that see track use or are in hot climates will also require a radiator upgrade.
The optional 3" exhaust upgrade includes a complete exhaust system right back to the tailpipe. Otherwise, the exhaust ends at the downpipe. The 3" system needs to be added to your order separately.
Not compatible with automatic transmission cars.
Remember, all FM products come with full Lifetime Support to the original purchaser!
