Oil Temp And Pressure

[sidewayssam]

hey all i have only recently bought a turbo skyline, it has a rb25det wit forged internal, im not to sure what oil temp or pressure is normal, the oil temp usually sits at around 80-95 depending on how im driving, im goinf to be using this car for drift and just wana know what the limits should be on oil temp and is i should get an oil cooler, also another thing, it has an apexi fc and im unsure what the knock gauge means, it usualy wont go above 10, what should the knock be at? cheers

Knock should ideally be at zero...though 10 is generally fine. <20 is ok too. Knock is bad for engines and generally indicates a bad tune or overly sensitive knock sensor, and is one of the many reasons for engine rebuilds.

Not sure what PSI oil pressure should be at.

Oil temperature is important, 85-90 is ideal. If your are taking it drifting an oil cooler may be in order but you won't know till you go.

85-90 is ideal between brackets.. if ur just cruisin around doing nothing other then that... no thrashin, then ur oil coolin system sucks balls. Introducing minimal heat into the turbo will make it go to 100 real easy. while ur drifting/thrashin the car, 80-90 is ideal.. Stays relatively "cool" enough so it doesnt thin the oil out too much.

If it strays over 110 while on the track, which will happen very quickly and easily, then pull over and let the shit cool down

I had an oil cooler on my previous RX7 and while being severly cained, on a 40deg day the oil temp never rose above 85.. awesome cooling (had water spray) but on a cold day... it would struggle to get past 60deg.

Oil pressure... around 20psi @ idle is ok.. even down to around 10ish is ok.. @ around 6000rpm ud want it be @ around 60psi (from memory)

Dude, as per your other thread, what Gary (Sydneykid) said is worth knowing.

Any track work Id suggest an oil cooler - any "row" cooler is better than no cooler.

I need to get an oil temp guage so I know whats going on.

my oil pressure sits on 2 bar on idle then climbs higher as i rev it anything up to 5 or 6 bar
