When going turbo is it recommended that you get a better radiator than oem since warmer air will be entering it or does oem work fine?

 

No need for a new radiator - you need an intercooler instead.

 

Depends on your setup. I tried to run the OEM radiator after my turbo install but ended up overheating. Had to upgrade mine.

Scott-

 

I live in Tampa, arguably the most humid climate on the east coast...been boosted for over 15k and 3 years...stock radiator with upgraded fan switch and thermostat keeps my coolant temps below stock at all times.

 

stock everything here. I run more water then coolant since im in florida. 70/30 water mix

 

a more effieicnt radiator couldnt hurt, nessesary no, a bad idea, certainly not

 

is a fan switch needed if you have a EMS where you can have the fans come on earlier than stock? I ask because I am considering the thermostat but not sure about the fan switch.

 

u can set it to whatever u want with aem ems, switch not needed

 

A larger radiator is always recommend in my opinion when going boost.

 

If it is only used on the street then you can get away with stock. If you ever plan on tracking it then you will need a larger capacity radiator. I say get one-you can never be to safe. What is cheaper; a new radiator or replacing the head gasket or motor when it overheats and damages something.
