Which thermostat should i run for my B16A turbo coupe? It is on 7lb's of boost making 286whp an 201trq
I went to replace my thermostat because my car started running hot "which later i found out was my Cooling fan not kicking on " I took out the original thermostat an went to Advanced for a new one. When i got the new one it was smaller than the one i had, which i figured out by the gasket that goes around the ring on the thermo was bigger than what they gave me???? Anyone have the specific part # or idea why this happened?
