it also depends on the guage you are using aswell.
usually you should not really on the actual figure it gives you but as a guide to determine each cylinder in relation to other cylinders. i.e picking out lazy/low cylinders
i have used different guages from old to new and different brands and they will all read differently. 210 on one guage could be 180 on another etc. i have even had 2 of the same brand guages on the same engine read differently

Fair call.
My stock bigport (220k km, never rebuilt) gave 145-150psi across all four under a dry comp test, with my cheapo supercheap gauge. It still packs a reasonable punch, but blows a little smoke under load, so rebuild time is coming. Dyno'd at 99hp@wheels with quads & aftermarket ecu.
I recall the manual stating 135-140psi is rebuild time.
It sounds about right to me,
my stock 100KW bottom end, with new pistons, and rings, 0.5 TRD Head Gasket, 270 ish cams, and quads,
comes in at 260 PSI across all four on the last cold test i did.
but we are putting out 95KW atw now.
Ben.
