Gauges
Ok guys,
i am sure that someone has already posted some info on this but i just can't find it.
I want to be able to have actual numbered readings for my coolant temps and oil pressure in my 2000 miata. I want to use the stock locations and i want it to look stock. Do i need do source parts like the oil pressure sender from the earlier miatas, or does somebody offer a complete kit.
thanks for the help fellas.
P.S. some sad news for the car and some happy news for me. I just blew all of my turbo money that i had saved up on an engagement ring. No turbo this summer

Installing a '90-'94 OPG is a straightforward operation on the later NAs, from what I understand, working inside the NB cluster is a bit more difficult. Here's a writeup: http://www.miata.net/garage/opg.html#Drake%20Daum and here's one that deals with changing only the sensor, and "linearizing" the factory gauge: http://www.miata.net/garage/opg2/index.html (very slick, IMO.)
As to the temp gauge, they all pretty much suck, but there is a mod you can do to make the gauge linear without replacing any parts. The site that detailed it went down long ago, and while I thought I had a valid link to an archive of it, it doesn't seem to be working. Use the WayBack machine and search for www.gravitydesign.net/saturn/miata/MTGLP.cfm

Not at all. If you follow the instructions you can have a nice set of linear gauges that match the rest of your instruments. You won't have the numbers, but with engine gauges exact numbers are far less important than trends.
When I did my temp gauge a few years ago, I bench-calibrated it so that 195° was straight up at 12:00 exactly, and mapped the rest of the curve to give me more resolution on the hot side. Here's how it worked out:
I don't need the numbers. I know that in stop-n-go traffic it's normal for the needle to get just to the right edge of the three horizontal lines, and if it goes further I have a problem.
