Up for auction are a set of flawless TWM EFI throttle bodies.  This setup is designed for Porsche 911 fuel injection conversions on 3.0 to 3.6 liter power plants with corresponding supporting electronics.  They have already been outfitted with 210cc Bosch fuel injectors and -6AN o-ring fuel rails for the next owner's convenience.
  • 46mm throttle plates
  • 170mm overall height from base to top of velocity stacks
  • Barrel centers are spaced at 94mm which makes these a bolt on for Weber IDA 3C manifolds or equivalent part# 200083 3003-46PR-A
The seller notes that this setup is ideally suited for high compression, high velocity applications where throttle response and air flow are maximized.

    @ManuPaulin the throttle plates are 46mm so the “choke” is just a hair over 46mm.
    When referring to fitting- what fitting are you referring to? ( bottom fitting )

  • Wassergekuhlt (seller) 3 weeksago

    @ManuPaulin Yes, the Weber linkage is a direct bolt-on fit to these ITBs
