help with keeping my sr20 cool - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

before i start i searched this and couldnt find exactly what I was looking for

just looking to squeeze every bit of efficiency out of my s14's cooling system

right now just have a koyo rad with FAL fans and a circuit sports fan controller wired in. i notice that my temps stay pretty cool but they fluctuate alot so my fans are always having to switch on and off even while highway driving...(basically killing the fan relays on me)
a friend gave me an upper radiator cooling plate to help force some more air thru the radiator...
Just looking at my setup i can see alot of other places where air can escape thru.
Does anyone have any suggestions of what I can use to fill these small gaps? Like some sort of foam or something that wont catch on fire under there
also is there any sort of lower cooling plate or lower shroud that attaches under the front bumper to keep air from escaping there also??

Basically i feel that while driving on the highway the fans should not really have to work too hard, but they do

sorry for the newb type questions..this is my first s14 and i bought with the swap done but not all the small details to keep this thing reliable under track conditions

I Agree if the pressure situaiton under your hood and those gaps and paths that air follows gives you a head-ache, re-install the OEM stuff, shroud, clutch fan, underhood plastics, the plastic under tray under the engine that everybody takes out, the plastic sections on the sides of the shroud, the plastics around the wheels, stuff like that.

I have most of the plastics int he wheel wells but that is what i was wondering..if this car has some sort of underbody panels that came from factory....i hate it when people remove these thinking they dont do anything....

i bought the upper radiator cooling panel to seal the top better but the bottom is wide open...does anyone have part numbers or anything for the zenki s14??? i try searching google and find no sort of stock underbody panels for the zenki....
i also own a mkiv supra and when i got it i noticed the previous owner never reinstalled the plastic underbody panels...i bought them all brand new from dealer and installed them and i saw a difference with temps on the highway mainly....also on a side note they made the car more stable and planted in the front at high speeds

i feel the s14 needs this cause its light and i feel it at high speeds..

what relays are you using? and yes not all relays are made equally. buy a quality relay is a good start.

I have been going through my car and buying every little thing that was missing as well as replacing every rubber seal, gasket, bumper that is no longer soft because of age. This website has been a lifesaver, the prices are a little high on some things but at least they have every little part number there is. Hope this helps.
