**Off-Topic: The catch can lines are not quite correct as pictured. To run this style catch can optimally, the valve cover needs to be modified. Mentioned because some people notice these things

Again, the GKtech fan is awesome. The stock clutch fan is great too. But to echo others' previous words- Electric fans make a cleaner look and offer better throttle response- and the right setup will do just as well.
Just food for thought- An S14 water neck w/ Stance water neck adapter for the turbo's coolant return has no fitment issues whatsoever with the S13 SR, and you'd never again have to fiddle with coolant lines between the engine and firewall.
Don't remember if your car is a daily, fair weather queen or track car, but anything you can do to make the coolant and oil systems better or more maintainable while you have it apart will pay dividends later on.
Hope this helps!
