This could certainly help. A block heater like mentioned above may also be useful.

Yes, it will. This is very similar to the factory oil cooler/warmer setup on the Turbo EJ2x(WRX/STI).

Sorry to bump, but....

How does this oil cooler compare to the Cusco version? As well, I daily my car, and currently have the Perrin oil cooler, so that may be overkill. I'm considering this as an alternative honestly. I don't track the car, just drive it hard on back roads occasionally.

Heat transfer properties are identical. Not sure if there are any significant differences in the fasteners and such.

Interesting, but hardly seems worth the trouble. There is hardly a decrease in oil temp worth mentioning. Definitely not adequate if you actually plan on tracking the car.

It's neat, and the write-up is appreciated as always, but I definitely can't understand why anyone would bother paying the money for this and go through the effort for hardly any gain whatsoever.

Depends on your level of tracking, its quite adequate for na cars for about 15 minutes hard use.

True if your boosted hard core track person its not suffient.

However its way cheaper that a radiator type oil cooler.
you dont have high pressure oil lines and fittings to leak or have to worry about rocks or something holing the oil radiator.

This thing is super simple and reliable and you can fit it in an hour or less.

few guys on here have leaks blown hoses fittings and even under bonnet fires with radiator types.

It will warm oil faster in cold climates, wont overcool you oil, and will take 10-15 degrees off your track oil temps on na cars this is usually arround 230-240 unless your doing extended sessions works well.
returns oil temps to normal very quickly on cooldown lap.

Anyone running this setup with a beefier rad?

I dont think the bigger radiator will help, i never see coolant temps over about 93 C, but the oil temps will climb to 115 or so after 10 minutes or so of hard use, down about 10-15c with no cooler.

This indicates the radiator is suffient, but the oil cooler cannot disipate head quickly enough to coolant.

If i saw the coolant temps climbing then a radiator would help.

What might help, and ive not tested is lower temp thermostat as this would increase the temp differrential between oil and coolant and aid heat transfer. Assuming that the radiator was suffient to hold the lower thermostat temp.

However, i would say if your exceeding the capacity of this oem cooler, just get a radiator style oil cooler, its the best option. The oem coolers are only good for hard street and low level track driving

Thanks, I use good oil so 110's to 120's oil temps is fine, as long as it does't go past 130 i'm quite happy

Hi steve,
i was thinking about it too, but i'm not sure the kit can be improved with a low temp thermostat if you use the car for both street and track

To me, the reason why i've installed the heat exchanger is to reduce oil temperature differential between street and track usage, so that i can choose the right oil for both (can't do that on a completely stock car).
A lower temp thermostat will likely lower max oil temperature at the track, but i'm afraid oil temperature differential between street and track will be the same, so you'll end up with the same "problem" in oil selection

yep lower temp thermostat just going to introduce other issues, best just going to thermostaticly controlled radiator type oil cooler fot heavy track use

Very late reply, but...

Cusco cooler will be more effective, because it takes cooled water after the radiator outlet and plumbs it into sandwich adapter, the outlet is plumbed into the radiator inlet (upper) hose.

The only problem is you have to cut up radiator hoses, and the price is quite high.
