Monitoring the S2000’s F20C Engine with Autometer!

With power and ground hooked up the wires were ronted up the A-Pillar and attached to the gages.  All wire was covered in split loom before everything was buttoned up.

Here are the gauges displaying oil temp reading the pan temperature.

The oil pressure gauge is reading nicely as well!

Now not only do we have a reliable supply of oil for our F20C engine but we can now monitor the condition of our oil in a much more accurate way than the OEM dummy lights that only come on when it is too late!  Thanks to Autometer, our S2000 can be a lot safer when being driven hard on the track.

    2. It is actually not a vertical hole, it just looks that way in pictures and its near other OEM pass-throughs.

  3. I installed my Oil Pressure and other gauges the exact same way. I was feeling kind of insecure thinking that there could have been a cleaner way to do it (of course there is), but knowing that others have done the same makes me feel validated.

  4. Where did you guys get the 1/8″ bspt to -3 an adapter from? I am having a hard time finding one! If you have extra, can I buy it off you guys 🙂 I’m local to socal.
