Radiator

We are proud to introduce the new Megan Racing high-performance aluminum radiator. Anytime an individual introduces their car to a racing/drifting environment, the temperature of the vehicle’s engine will skyrocket. One common and effective method of reducing engine temperature is to employ an aluminum radiator.

This is a cost-effective upgrade that can ultimately save an engine during competition or spirited driving. Often times, a temperature drop of twenty degrees or more will be noticed when using an aluminum radiator. Also included is a 1.1 BAR radiator cap.

Why Upgrade to a 3-Row Radiator?

Factory cooling systems struggle with:

• Higher boost levels

• Aggressive track sessions

• Drift events with limited airflow

• Hot climate street driving

A thicker 3-row core increases coolant volume and heat dissipation.

Installation:

Please FLUSH the radiator before installation and properly take all the air pockets out. If it’s not properly installed, might cause the motor to overheat due to low coolant or air pockets in the cooling system.

Megan Racing MR-RT-NS13 SR20DET Radiator Performance Benefits

• Lower operating temperatures under boost

• Improved consistency during drift or track sessions

• Reduced risk of overheating

• Better support for upgraded turbo setups

If you’re turning up the boost, cooling isn’t optional.

Installation Notes

• Manual transmission models only.

• Confirm radiator hose orientation for SR20DET setup.

• Inspect thermostat, hoses, and water pump during install.

• Properly bleed system after installation.

Drift rule: oil pressure first, coolant temps second.
