RB25 Cooling Systems
Currently in the process of RB25 Neo swapping my S13, trying to gather info on the best coolant system setup for this car. Things like what radiator to buy, what fans to use. I've heard rumors of using the stock clutch fan even. Any help would be much appreciated.

I cant imagine a stock clutch fan fitting with a stock radiator support.
A few friends of mine have notched their radiator support to tilt the radiator forward a bit for fan clearance, best bet is to just make a pair of derale fans fit. Suckas flow 4,000CFM's |

guess it depends on what mounting kit you're using.
In my case I build my own brackets and set the engine as far back (towards the firewall) as possible. This, along with a little trimming of the fan blades, allows me to use the clutch fan by mounting it on the other side of the clutch. Same thing on my 14, and ive been driving that one for years with this setup and it's never overheated (without a/c).
