Yup a alarm for the oil pump is a great idea.
Yes I got a mechanical pump with brass gears. Noisy but more reliable from what I've read. Now you got me reading about water meth injection ..damn
I'm also looking for the worlds smallest gauges for boost and air mixture. I have a 4# spring, a 6 # spring, and a 8# spring for the wastegate. I'll be starting with the 4#. I think it's easier to tune up.
