I've decide to fill in the empty single-din slot in my 2003 with three 52mm "gauges": a clock, voltmeter and maybe an oil-pressure gauge. What range is recommended for oil-pressure? The VDO series I'm looking at comes in 80, 100 and 150psi models.
I'm not looking forward to the plumbing required to add an after-market oil-pressure gauge -- I supposed I might as well relocate the oil-filter as part of the process.
