A couple of my buddies who are into drifting use the one i linked below. They drive an hr + then beat their cars then drive back home with no overheating issues. They say good fans, a good rad, and low temp thermo is the key. I have this rad and am looking to use Ford Taurus or Altima fans. I will be adding a low temp thermo as well, prob a 180 degree. This rad fits between the S14 rad location with no mods.
