Description
  • FP Ball Bearing Turbochargers for the Evolution 9 will use our Evo 9 Oil Line Feed from Head kit.

    We no longer recommend using oil supply from the cylinder head for the FP RED™ for the Mitsubishi Evolution 9 or FP BLACK™ for the Mitsubishi Evolution 9 in journal bearing applications. Oil pressure measurements made on various engines indicate that in many cases the amount of available oil pressure at the cylinder head feed location is less than adequate. The factory head feed location prioritizes the turbo oil supply lowest, after all other oil supply duties within the engine. These turbochargers require a minimum of 45psi of oil pressure under full engine load, and sourcing oil supply from the cylinder head simply does not meet this requirement.

    The filter housing source is much higher pressure than what is available at the cylinder head. Relocating the oil supply to the oil filter housing allows the turbocharger to be fed a sufficient supply of oil pressure and volume.

    Some people may insist that 20 or 30psi of oil pressure is sufficient to supply a typical floating journal bearing turbo, it is our specific experience that this is not true in the case of an automotive racing turbocharger used in a performance application where excessive EGT, high shaft speed and maximum thrust load are the norm, not the exception.

    Currently, damage resulting from insufficient oil pressure could still be repaired under our Complimentary Repair Policy at our discretion.

    The graph below shows how oil pressure varies at different locations within the EVO 4G63 engine. You can see how much lower the pressure at the cylinder head is than the oil pump very clearly in this graph.



    Our new oil line, pictured above, will supply you with a block off bolt for the stock head feed location and all the supplies needed to feed your larger journal bearing turbo directly from the Evo's oil filter housing. Included in the kit are the following pieces:

  • 1 - 35" Length 1/4" JIC 120* Bend Hose Assembly
  • 1 - 24" Length 1/4" JIC Straight Hose Assembly
  • 1 - FP -4 AN Inline Filter .125" orifice for Journal Bearing or .036" orifice for Ball Bearing
  • 1 - Filter Element
  • 1 - O-Ring for Inline Filter Housing
  • 1 - 3/8" BSPT to 1/4" Male JIC Adaptor
  • 1 - 12mm X 1.25 Banjo Bolt
  • 2 - 12mm Crush Washers
  • 1 - 10mm Plug for Stock Oil Feed Location
  • 1 - 10mm Crush Washer
  • 1 - 1/4" JIC Union Male
  • 2 - Cable Clamps
  • 5 - 8" Zip Ties
