If you decide to get an oil pressure gauge, get the temp gauge as well. Oil
pressure is nice, but because it is related to temp, you want to know when
you're running low pressure for a given oil temp. For instance factory spec
is 2 bar at 80C for a new engine.
Now, if you get a dual-pole sender, one pole for gauge one for light, be
aware that the switch on the oil light pole has a higher cutoff than stock
.3 bar. This means your low-pressure warning and oil light will come on a
bit earlier and scare the heck out of you. Simply use a splitter, run it
off the extension hose, and screw in your stock .3 bar oil pressure switch
there.
I'm using an Audi gauge cluster which came with both oil and temp gauges.
If you decide to go with a euro 5-bar gauge, beware that 5 bar is about 75
psi vs the 8psi gauge in the Bus Depot kit, so your bar gauge may read about
.5 bar too low and scare the heck out of you. I'm not even going to get
into running a 170C temp gauge on a 150C sender. :-) Well, my gauges were
free.
Then you'll just HAVE to get an external oil cooler. Trust me, it's all
addictive as heck! Let me know when you're ready.
