RB30 TPS to Mazda Mx5 B6 Throttle Body Adapter

Recently there has been some interest in fitting a variable TPS to the 1.6L Mx5.  Like me a lot of people aren't too keen on cutting the TPS shaft and taping the extra holes on the throttle body.  For those people I give you a link to the Google Sketchup files I used all those years ago when I made mine.


  • You will still need a tap for the inner holes (reuse the stock bolts).
  • Slight modification might be needed to get it to fit (see picture below).
