I've been studying what can be done to the FRST in order to prevent engine failure.

Daz article about the modification on the T2 turbo oil return is so simple and very usefull:

I would like to take a few steps further and one that I really dont know is about oil cooler.

As everyone knows, oil must be at certain working temperture, so cooling it down that level is going to be bad. Is it really necessary the oil cooler? what size, since it cant be too big avoiding too much cooling?

Anyone have done this?


going even further: what about how to give the head a better lub? cam wear is a pain on the CVH engine.

More important to make sure it's changed every 3000 miles tbh

but that's basic rule.

Now you go for a trackday and drive hard for about 30min a session. The oil its too hot to get the job done. Something is going to breakdown.

no matter what oil you use, could not be good enough if the oil is way above good working tempeture.

I just cant tell if the FRST needs a oil cooler.

I'm seting the car to 180bhp on a modified T2 to T25 internals.

Buy my 19row oil cooler and sandwhich plate stat plus pipes.

Excellent for track days and keeps the oil super cool.

Any turbo thats supposed to take track abbuse will need an oil cooler. And the FRST oil to water unit probably won't be up to the job. The best way to make sure the oil stays at the right temp is getting an oil to air cooler and a sandwich plate with a thermostat (which will only allow oil flow to the cooler when a certain temp is achieved, a bit like what happens in your cooling system) so all you have to worry about is having a big enough cooler to stop those temps from climbing.

I know my car is a little different, but I think the standard FRST oil cooler should be up to the job if a good quality oil is used. I emailed Shell UK about the temperatures of it's Helix Ultra 5W/40 fully synthetic oil, which they say will survive sump temperatures of over 150 Deg C and recover completely when it cools.

With track use of my car I have had the oil temperature up to 130 Deg C without harm to my engine or turbo, both of which have covered nearly 100K miles and appears to be in good health. The only issue I have with the standard oil cooler is that with track use it will put extra strain on the water cooling system due to high temperatures, therefore removing the standard oil cooler and replacing it with a thermostatically controller take off to an air to oil cooler should improve things all round.

However if you do not intend to use your car on the track then the standard oil cooler should work fine.

Finally remember that if you do get the turbo very hot allow it to cool with the engine running or you will bake oil onto the turbo oil feeds, thus reducing flow and slowly killing the turbo.
