FC3S Non-Turbo Ford F-series TPS bracket and fitting

thingiverse

These are some parts I made to adapt a circa 1995 Ford F-150 / Bronco 5.0L V8 throttle position sensor to the throttlebody of a 1988 Mazda RX-7 13B non-turbo engine that has a MegaSquirt MS3x standalone ECU. A few notes: My non-turbo throttlebody was already modified to remove the thermowax and secondary throttle plates; the bracket won't fit otherwise without modifying the base. You will also have to modify the a bracket on the throttle shaft in order for everything to clear properly. The fitting and bracket MUST be printed on their side, otherwise its layers will separate and break. Chase the threads with a tap. Or, add in an appropriate metal insert. The designs of this bracket and fitting have yet to be road tested and I can not guarantee its long-term durability. Only fitment and basic functionality have been tested so far. As in the bracket and fitting fit, the sensor fits and consistently works with the ECU. The engine itself has not been run yet nor any road tests made. Use at your own risk.
