R35 ITB set up complete

ASNU’s SEMA award winning ITB system for the R35 GTR

  • Aids throttle response as the plenum no longer has to be pressurised after opening the throttle
  • Increased runner and plenum volumes allowing for bigger HP and torque
  • Built to allow the more extreme cam profiles to be used in a road situation with minimised idle problems
  • 60% increase in throttle area over largest twin throttle currently available (72mm)
  • 74mm Plenum inlet flange that can be increased to 78mm ( 23% increase in flow over 72mm twin throttles )
  • Light weight alloy plenum housing to withstand extreme boost at a high fatigue life
  • It ensures a more equal distribution of workload across all cylinders by the engine allowing more HP to be generated safely
  • Plenum optimised for volume and flow using F1 technology
  • Complete with 6 additional ASNU SC injectors in a location optimised for that specific design
  • High flow upper fuel rail utilising -8AN fittings with a 17mm internal bore
  • Upper fuel rail designed to operate with integral fuel pressure & temp sensor
  • Designed to operate with the ASNU R35GTR fuel rails with pressure sensor (requires sensor to be relocated to the upper rail location)
  • Designed and machined with pre centre drilled bosses for Nitrous or ADI/water methanol injection
  • CNC machined from billet 6082 & 7072 Alloy.
  • -8AN vac balance pipe between banks to give a good idle and avoid traditional ITB setup issues.
  • -8AN Boost balance pipe.
  • Vacuum and boost ports, with brake booster vacuum take off
  • Designed to operate with the GTR’s original throttle motor internals (not supplied)
  • Utilises stock MAP sensor (not supplied)
  • Constructed to road car levels of durability, allowing extreme HP daily drivers
  • Integral air trumpets built into the plenum back plate
