Preventing Oil Temperature Increase in GR86/BRZ

Machined Aluminum Attachment with Thermostat

To address the problem of oil temperature exceeding 130℃ during track laps in the GR86/BRZ, a machined aluminum attachment with a thermostat is now installed. This attachment is designed to prevent the engine oil from increasing in temperature and causing viscous friction due to overcooling. It's important to note that the 12 row oil cooler core is placed inside the bumper in front of the left wheel, while the stock front bumper louvers are retained.

Compatibility with Supercharger Kit and Front-Mounted Intercooler

For NA vehicles, the attachment cools the engine oil without interfering with the radiator's operation and can be used with the front-mounted intercooler of the GT2 supercharger or bolt-on turbo kit. Additionally, this attachment accommodates the different bumper openings of the GR86/BRZ by adjusting the oil cooler duct opening to any desired width. The press-formed louvers installed on the inner fenders vent hot air efficiently and protect the core from debris damage.

Machined Aluminum Oil Take-Out Attachment

Another newly designed attachment for the GR86/BRZ is the "machined aluminum oil take-out attachment." This attachment lowers the filter height below the AC pipe by 22mm and allows for the mounting of defi gauges, oil temperature, and pressure sensors on the adapter thermo. It's important to note that it is compatible with a supercharger kit and the washer tank must be replaced with the tank in the kit. Finally, the attachment also has a flap function at the end of the duct.

The machined aluminum attachment with a thermostat is a reliable solution to preventing oil temperature from exceeding 130℃ during track laps in the GR86/BRZ. It's also important to note that it's compatible with the front-mounted intercooler of the GT2 supercharger or bolt-on turbo kit and accommodates the different bumper openings of the GR86/BRZ by adjusting the oil cooler duct opening to any desired width. Additionally, the machined aluminum oil take-out attachment provides more flexibility in mounting defi gauges, oil temperature, and pressure sensors on the adapter thermo.

The washer tank must be replaced with the aluminum tank in the kit.
It is designed to placed next to the battery for ease of refilling.
