I was investigating a coolant leak on my autocross car this weekend and noticed some steam coming from the area near the lower radiator hose. I have not seen any leaking since tightening the drain valve, but at one point I was thinking that I was going to need to get a replacement. Has anyone run a smaller radiator in these cars? Does anyone know what someone might use in, say, a lotus 7 replica with an f20 motor?

oh, and along the same lines, has anyone done an electric water pump, or a smaller alternator?

Thanks!

 

This is a drag car but hes running an electric water pump and smaller rad....Post #16 for more info.
