Radiator
Thermostat
The stock thermostat your engine is already equipped with is fine for turbo charging the motor and you should see no problems. If you live in higher temp climates and/or turbocharging while keeping a A/C system, the 170deg thermostat might be a consideration if your having higher then normal engine temps.
Radiator Fans
Types of fans, fans I’ve found there are 2 types of fans expensive and cheap. I personally have only used cheap fans under $50 for a pair and have not had any problems. Expensive fans may have advantages far as CFM, longevity and design thickness and are worth considering.
Styles of Fans: This is more of the more important aspects of the fans. Witch are curved blade vs straight blade. I’ve used both styles and i prefer the straight blade design. As with everything the 2 have disadvantages and advantages. The curved blade are usually more common and cheaper, the design sacrifices some cooling CFM with the curved blade that is designed for less noise. The Straight blade has a higher cooling CFM with more noise then the curved blade. Personally, I have found the noise difference unnoticeable.
