I saw a post in a thread somewhere on here.. and damned if I can find it now... Where someone removed the factory Oil pressure and water temp gauges and replaced them with real aftermarket 1.5" gauges.

I was SURE i had bookmarked it, so I could follow their guidance for my own car. Well, I bought gauges that match my Revlimiter gauges pretty well and now I can't find the thread.

Does anyone happen to know which thread it was in?

Thanks!

One of the LFX guys I've been following replaced the whole cluster with Speed Hut gauges. I know the stock oil pressure gauge can be made more accurate by swapping in a 1990-94 sender and gauge (if your car does not already have one) and the temp gauge can be made linear with a modification involving a few resistors.

I've done the temp gauge mod and still wasn't happy with the performance of it. I wound up picking up a set of electrical equus gauges for the water and oil. With some minor mods I can make them work it looks like.

 

Depending upon what engine/car you are swapping, this could work for you...
I put an LS2 into a 2004. The stock Miata temp sender threads right into the LS head on the passenger rear side. (The heads are the same. Each has a water port. The LS PCM uses the other one, which is on the driver front side.) One wire from the sender feeds the OEM Miata gauge on the cluster. Done.
