Oil Cooler : Nissan Skyline GT-R 2018 Upgrades

R34 GT-R, C-West bumper, ARC oil cooler

Its a good idea if you are going to go on a track, or do any high speed driving with the car to put an external oil cooler on the car. On a track, it only takes a few laps in cool outside temps to get the oil temps above the 110C range. As important as the cooler itself, is the ducting to and through the cooler core.

We bolded and underlined that last line, because it is very important. If you look at any modern car, or look at any kind of race car, ducting in and out of the core of a cooler is managed. Air is lazy. It takes the path of least resistance. Since you bought the cooler, you want the air packed at the front of it to pass though the core, not pass around it. By adding proper ducting, the air will pass though the core, raising efficiency tremendously.

More oil cooler information. 

We had this question recently, what is out there as a kit for a BNR32 Nissan Skyline GT-R.  So lets see.  With an oil cooler you want the largest lines possible. You want the least amount of 90 degree fittings possible.  Steel braided lines, and a remote oil filter mounts are big pluses.  If you don't want to make up your own kit, here are a few off the shelf that you can buy

Other Options: 

1) Make your own oil cooler kit.  You need a core, fittings, and a filter adaptor. It is not a difficult thing, but once you piece one together, you realize how expensive it can be.  Don't buy a shitty core. Buy a Setrab oil cooler core.  Use -12 AN fittings and line. Use the least number of 90 degree fittings possible. Try and duct air through the core, that is in and out.



2) Used oil coolers.  Buying a used oil cooler, is kind of like buying used underwear.  Some people are into that, but you want to make sure you clean them really well before you use them.  An ultrasonic cleaning, of the oil cooler, not the underwear, is in order.  A perfect example of a unique setup is the ARC below.
