Throttle Bodies

2000 Series ITB's (Individual Throttle Bodies )

Want to use your stock Honda injectors? This is now possible. Order your 2000 series kit with the appropriate fuel rail and injector adapters at no extra charge.
Designed with the serious motorsport competitor in mind, the 2000 Series brings the advantages of individual runner performance to many of today’s high output engines. These units breathe through four throttles into a runner designed to be a straight shot to the cylinder head where it joins the port at the optimal angle for maximum flow.

  • Includes high capacity -10 fuel rail and adjustable pressure regulator which flows up to 700 lb/hr.
  • Four individual throttles.
    The industry standard is to measure the throttle plate diameter to establish throttle size, not to measure the air entry or the air horn diameter. The throttle diameter quoted is the true throttle plate size.
  • Four injectors included. Our injector position is optimized for maximum horsepower. We can supply the unit without injectors if requested.
  • Our billet linkage included.
  • TWM full radius air horns included.
  • Designed for use with aftermarket injection ECUs (Electromotive or Haltech )or modified and reprogrammed stock units [for example, Hondata].
  • Weight: 2.8 Kg, 6.2 l

  A Note Regarding the B18 Kits
Please note that "Type R" engines, while referred to as B18s, in fact use the B16 cylinder head.
Therefore, when ordering for a "Type R", you should order the appropriate B16 part number.

Owing to extreme installation difficulties, and the complex nature of this design, we have decided to remove this from our future products. It is possible to make throttles for the ENGINE but the installation in a Celica GTS is impractical.
