Application

- Replace 2004-2005 Mazdaspeed MX-5 SE turbocharged BPT with IHI RHF5 VJ35 Turbo VA430091, VB430091, VC430091, VD430091. The turbo is not a drop-in type, but it has the same turbine housing as the stock version. You will need to modify the intake pipe to fit the compressor housing. If you choose the BOV or BCV option that will hit the stock manifold, you need to modify the position as well.

- Horsepower Range:

300-350HP (19T 46/56 mm Trim 63) for Gasoline
320-370HP (20T 47/56 mm Trim 66) for Gasoline

- The maximum power stated for each turbocharger has been calculated based strictly on the choke flow of the compressor map (total turbo capability), representing the potential flywheel power. This product's Performance results depend highly on your vehicle’s modifications and tuning/calibration.
