You very well may be.........

EGT is critical for the novice, and pro alike.   It tells you where our
playing in relationship to the thermal limits of your engine.

Water cooled cartridge for the turbo has little inpact on the oil temp
feeding the engine bearings....  Cooling the cartirdge is to min oil coking
in the turbo.

Buzz words turbo overheating, you can percolate oil til it easily losses it
ability to lubricate bearings!.

Measure the temp., and see where you are.  Get a temp., and call Earls' or
someone to get a rough idea of what you need.  Why bother putting one on if
it's not sized right.
