Oil temperature is also critical because as oil goes above 230 F it really starts to degrade in performance. EGT is nice, but really should be linked / integrated to your wideband and trigger an alarm / boost kill if the temperature gets too hot (as can be done with Zeitronix). IMHO, ideally all of the parameters listed could be integrated to the wb or ECU and triggers set for each as it is very hard to monitor gauges while you are driving aggressively....

I am using the VDO gauges (a nice kit found at www.42draftdesigns.com ). There is a great write-up in the How To section and the instructions that come from 42draft are spot on (actual Evo install instructions vs. generic) -- it really is easy.

You cannot get a different oil temp gauge and use the factory sender -- the gauge and the sender are designed / calibrated as a unit.
