oil pressure?

I have one of those cheap oil pressure gauges on my 101 3.5V8 - pressure is 30 - 40psi depending on revs.

What ? All you need for oil pressure is around 10PSi/per 1000RPM ,I think your 80 PSi , and 95-105 PSI is actually KPA , so divide them by 7 which is 10 PSi and 12 to 14 PSi .
If it had more than 75PSI it would blow the Oil filter off
Excessive oil pressure is ususally indicative of excessive restriction somewhere or a very faulty relief valve . Do you realise the amount of force that 100 PSI represents at the main bearings , you would be jacking the main caps off !!! apart from the great parasitic losses at those pressures , Never confuse pressure with Flow , Flow is what is important , the resulting pressure is only the resistance to Flow . put simply.

NO its definetly psi, thats what the mechanical gaiges read.
both cars have a balance shaft elimination kit which would cause an increase in pressure

Balance shaft ? what engine have you been talking about ? Dont recall ant RRC engine having a balance shaft !
Still 75psi or 80 psi , you have something seriously wrong with the engine if those pressures are correct . ( sounds like someone likes shimming up the relief valve )

its not a range rover, both 4g54 (Mitsubishi sigma and scorpion).
