1999-00 FM IIR turbo system
The big daddy of the FM turbo system lineup. It`s a good option for track cars or anyone who`s looking to build a lot of horsepower. Minimum power levels start at 250 rwhp.
The big feature of the FM IIR is the external wastegate. This means more stable boost control, especially for big turbos and high boost. The Turbosmart wastegate can either be attached to a 3" stainless steel divorced flow downpipe or to our stainless steel dump tube with a separate 3" downpipe. The dump tube is not recommended for street-driven cars as it`s quite loud.
The turbos themselves range from the GT2860 to a massive GT3076, suitable for power levels running from 250 to 500 hp at the wheels. We specify an anti-surge housing (not available on the GT2860) to avoid compressor surge problems with the size of these turbochargers. All but the GT2860 turbo will require substantial cuts to the frame rail of the car, and we recommend a gusset be added. At the power levels offered by the larger turbos, some chassis reinforcement such as seam welding or Frog Arms is a good idea. Available turbos are:
GT2860
GT2871
GT3071
GT3076
The smallest turbo is a bit larger than the standard GT2560R used on the FM II, so it`s a bit less responsive at the 250 hp power level. However, it`s what we`d recommend on a track car as it will run a bit cooler. It also has more ultimate potential if you build the engine.
The rest of the system is the standard, proven FM turbo hardware. Our strong cast turbo manifold feeds the turbocharger. Our exclusive formed silicone intercooler piping gives superior internal flow and fewer failure points than pipes made of pieced-together steel. Our exclusive Inconel studs and Stage 8 hardware are standard. The blowoff valve is vented to atmosphere. Two different sizes of intercooler are available. And of course, the downpipe is covered by a lifetime warranty.
And of course, the best hardware in the world is no use without good engine management. And that`s why we include the Hydra Nemesis with the FM IIR. Not only do you get full control over fuel and timing - of course - but you have the ability to run fully integrated water/methanol injection (not included) for maximum power on pump gas or to take advantage of alternative fuels such as E85. We also include 1000cc Injector Dynamics injectors to feed the beast.
The downpipe is a 3" unit that uses a different flange than stock. You will either have to use our 3" exhaust system ($714, including a catalytic converter) or build your own. If you`re running on the track and don`t have to worry about noise restrictions, a simple dump tube would work.
Since many of the parts are shared with the standard FM II and the Voodoo turbo kits, they can be upgraded to FM IIR spec without too much difficulty. Please contact us if you are interested.
Prices vary depending on the turbocharger selected as well as other options. Please give us a call to order your FM IIR.
Dyno run - compared against a typical FM II on a 1.8 engine and using the standard GT2560R turbo. The FM IIR is on an FM stroker and uses the GT3071 turbo size.
