(1/8 pt fittings). Wondering if anyone has one of these installed on their mr2 and if so did you go for the 'standard', 'short' or 'small' 3/4x16 option in the drop down selection?
(although some may interfere with the aircon belt) with the added bonus that fitting does not involve dropping the oil (unlike the sump location) nor potential leaks from sandwich plate seals. Just get some adaptors and fit using PTFE tape 
(probably Internet lies as usual) that they weren't the best points to measure from for reasons I can't remember. Have you mounted there before with successful realistic/ reliable readings then?(Assuming you used sensors with 1/8pt threads)GTMatt wrote:I had read on other sites about those locations, but also
- in terms of the flow of oil through the engine, they'll give essentially identical readings to a sandwich plate. The oil leaving the rev3+ filter (and hence sandwich plate) goes straight through the pipes with those plugs in... well, for temperature I'd say it is the best place. It's measuring the temperature of the oil going directly into the engine, not the temperature of the oil at the bottom of the sump. However, for pressure there's a convincing argument to say that the stock oil pressure location is better, because it's at the top of the engine and therefore is sensitive to more potential failure locations.- I have both the sensors plugged into those locations. However that's because I previously had a sandwich plate and I wanted to see the same reading on the pressure so I could understand how my new oil cooler affected pressure; changing the sensor location at the same time wouldn't have told me anything if the pressure reading dropped. If I were installing afresh, I would put my temperature in one of those three ports and my pressure Tee'd onto the stock pressure switch (using braided line, as solid T pieces are known to break under the weight of two sensors) Thanks(3/8bsp to 1/8npt), the defi senders are 1/8pt which is a Japanese spec which is functionally interchangeable with bspt threads. That adaptor has a 1/8 npt thread (American tapering) so the two would not thread into one another, Is that the exact one your using? Tad confused.

Npt for temp, bsp for pressures sensors.
Strikes me as odd.
Some forums threads say one, some say the other.
My Defi sensors (both temp and pressure) are using 1/8NPT threads just fine shinny wrote:If you have a rev3+ engine, there's a better way to do it:
Three 3/8 BSP ports available
- not that I have any gauges to hook up but still nice to know those ports exist There is no stock oil temp sensor so the manufacturers expect you to add a sandwich adapter.....and they all have 1/8npt ports

..I don't go for the JDM gear so I didn't know that = coolness

. talking b0ll0cks(defi site) http://www.defi-shop.com/installation/sensor/ and states 1/8 pt which as I've previously stated is not the same as 1/8 npt. But having said that I ordered an adaptor as posted by shinny and received it today, the sensor threaded into it perfectly. Which means they weren't bspt or the sensors aren't np as per the link above. 'pt is just a random thread that screws into Npt but not bsp.LukeSi wrote:Out of interest, howcome Toyota never utilised these for anything out of the factory?
.. I have no idea why they're even there TBH! They're pretty useful though
