Currently running T3/T4 B20/VTEC. No cooling issues with stock Si radiator and 160 deg. thermostat. When sleeved will I need to run a 2" aluminum radiator to keep the engine cool or will the Si rad still be enough? Anyone have direct experience with this upgrade and then a cooling problem? Thoughts?

Thanks in advance...

 

i would like to know the same...

 

ill be running my oem rad with my b20/vtec. but i have an electric water pump. I do plan on ditching the stock rad regardless of how it cools

 

I've heard of people using an electric water pump. What's the scoop? (ie; remove thermostat and pump always working???) Where does it get installed?

Thanks...

 

you should have no cooling issues with the si rad. i am running one ane a built sleeved b20/vtec and have no cooling issues with the 1/2 rad.
