Guys,

I have a MY99 RB5 with the following :

I've recently installed Oil press, Oil temp and Boost gauges.

I've installed the sensors using a plate from Scoobyworld which lets you install 4 sensors using the oil filter connection. I've installed the press sensor and temp sensor into this plate and have the following readings :

Oil temp when warmed up is between 85 - 95 celsius

Oil pressure -

Cold - Idle or Moving 100 psi
Warm - Idle 40 psi, moving 95 -100 psi

The oil I'm using is Mobil 1 motorsport 15w50. When I had these gauges before on my STI RA the oil pressure was about 80 - 90 PSI when warm and moving and the same Idle pressure.

Before you ask I have put this on the RB5 site also.

What could cause this high pressure as I don't think this should be so high.

 

pressures sound normal for a 99.. the STi RA was an earlier car I presume?

Yes the RA was a 96

 

All sounds normal.. the oil pump is slightly larger on the 99.
