Mazdaspeed FMII conversion kit

The Mazdaspeed MX-5 (or MSM) is a good platform for modification. But eventually, the limitation becomes the stock turbo. We tried modifying the turbochargers but were not able to get the consistent results we needed. On top of this, stock MSM turbos have been known to fail. So, what to do?

Meet the FM II conversion kit. This allows you to install a very reliable, nicely sized turbo into the MSM. The conversion uses the high-end parts developed for the FM II. The exhaust manifold is designed for good flow and moves the turbo higher up for more available space. This space is put to good use by the turbine outlet casting, which keeps the turbine and wastegate outlets separated for the best flow. The stainless steel downpipe mates to the MSM exhaust. Meanwhile, the intake piping is very open with a cold air box while the piping to the intercooler is replaced with our large-bore silicone tubing with fewer bends than stock. It's all good stuff.

Dyno run of a Mazdaspeed with the FM II conversion, a Hydra, FM intercooler and FM exhaust. The car's on 93 octane pump gas. How's that for a power jump?

There's a selection of turbos as well. For better response than stock with a similar maximum horsepower level, we have the small GT2554R. For similar response to the stock turbo yet with the potential for approximately 60 hp more power, we have the GT2560R. For maximum power (and built engines), there's the big GT3071R.

Included in the conversion kit is a new intake, exhaust manifold, downpipe and compressor-to-intercooler piping - plus, of course, the new turbocharger. All the water and oil lines bolt up to the MSM parts, as does the downpipe. Naturally, the downpipe includes a catalytic converter (not shown in picture) and has a lifetime warranty.

The kit does not include any engine management, an intercooler or anything between the intercooler and the throttle body. It's intended as an upgrade for a car already equipped with a Hydra, although it will run at lower boost on a stock ECU if an O2 signal modifier is used. If you have an almost-stock car, you can get all the parts bundled together in our full FM II upgrade.
