I fitted a generic oil cooler about 6 months ago and have been a bit worried about my oil pressure.

On cold start at 3000rpm it is at, or over, 100psi (aftermarket pressure gauge)

Even when warm I am seeing around 70psi at just over 3000rpm and it's starting to worry me.

I thought it may have been the oil I was using (Motul 8100 - 5w-40) as it was getting to its 5000kms change time, so changed to a 0w-40 but the pressure is still the same.

Does anyone else have high oil pressure with one of these kits?

I'm starting to think maybe the cores are a bit restrictive causing the rise in oil pressure. i have checked all the lines and there are no kinks or anything and it is all plumbed correctly.

With a track day coming this thursday I want to sort it out beforehand if it IS an issue.

Any advice would be appreciated.

I see similiar oil pressure around 2000rpm when the motor is cold.

Your seeing it when warm? :S

Yes. I will have to get the oil up to full temp ~80 degrees and check the pressure then. It's a bit hard though because with the cooler it normally sits at about 70 degrees unless I am thrashing it

well i have noticed the cheap chinese oil coolers seem to have very, very small passages through them which could certainly cause high pressure.

anyway, forget the cold pressure. what is important is the pressure at operating temp (ie 80+). 5 kg/mm at 3000rpm is actually not that high oil pressure. i'd say it's about right, or even a touch low. BUT the issue here is what was the oil pressure like before the cooler? if it was lower then obviously the cooler is a restriction.

Can't comment on the pressure before the cooler was installed as I didn't have an aftermarket gauge and my factory ones is crap. When the autometer gauge reads 70psi the factory one is on or about the 3 mark :(

    • I know people cry at the price of the Getrag 12-14k for a conversion now, but it really is a nice mid point. Not going to get change from 10k on a gearset installed.  $30k++ for sequential.   I know you run the risk of a damaged used one and parts are hard to get but as a street car gearbox its really hard to beat. If you enjoy a more traditional manual, its the choice no question.
