Was just wondering if there are any walkthroughs someone has made in the past about installing a:
exhaust gas temp guage and a water temp guage.

 

Water temp:

EGT:

People have different opinions on its location. People say best choice is to get dual gauges and tap into each exhaust runner for each rotor. More economically, use a single gauge and tap either pre-turbo (manifold) or post-turbo (downpipe). Pre-turbo would be better accuracy but I suppose it is possible for the probe to break off into your turbos and chew them out (and its just harder to get at in general).
