Yes. A small Mishimoto 19 row oil cooler. Most small engine/small-high pressure turbos will run very high water and oil temps. Especially when I am at full throttle most of the lap. Porsche Caymans which are NA run 270 degree oil temps all day - go figure. I run Amsoil racing oil which is the best for high temps and low evaporation. The next upgrade is a dry sump system with a cooled-remote reservoir in back. 🙂
@@PFCoach44 makes sense, I have also seen the same thing regarding oil in high temp scenarios, seems kinda normal for these 4 bangers. I use motul 300v, I wonder how that would do compared to amsoil. I want to throw on a thermostatic oil cooler for my STI , maybe I will just go a custom route and get something a little bigger with custom brackets. I also heard running a bigger oil pan, like killer b, gives you a slight decrease in oil temps as well. Thanks for the reply. My car is mostly street driven anyways, but I tend to push it hard on the highway so its helpful to see what other people run.
@@arvinbijan Also realize that the oil temp sensor is in the oil pan. Therefore, this will the hottest the oil will be because this is the oil leaving the hot engine. You can expect the oil leaving the oil cooler before the oil pump into the engine will be about 20 degrees cooler. Note: For track use, both water and oil thermostat are removed. Less points of failure. Also most oils break down and are damaged after a constant 270 degrees.
It is very beneficial to relocate your turbo to the rear of the car. Tremendously reduced engine bay temps plus more oil and longer routing will allow for good cooling all still with the wet sump oil system. Can have larger turbo, PT6260 maybe. Better corner balancing, better cooling, cooler intake temps, can even have water to air intercooler or just do not have one at all. Cut the hood scoop and rivet on racing louvers. So many benefits for low cost. And the turbo lag is existing on the paper but is not noticeable while racing, especially if you can and will left foot brake to add a little brake boosting to your advantage. And you can move the alternator closer to the firewall by making a dummy pulley with the extension rod which will extend from the dummy pulley to the alternator at the firewall. The perfectly balanced Subaru STI Hatchback.

great video. I have a sti hatch. what is the name of that touch screen that shows all your gauges?
Do you run an external oil cooler? those oil temps seem kinda high or no?
