please can someone tell me how hard it would be to install an electric fan on my z32 instead of the stock viscous one. does anyone do kits at all???

Yes there are kits but the viscous fan is more capable than any electric kit and the consensus of opinion is that leccy fans are not worth the agro and cost of fitting and are not up to the job!

Bit of a unknown one really imo, very few if at all guys here have tried or actually have electric fans and for those in the US who use em, have no issues that i've seen.

It is a known upgrade on many performance cars from the late 80's upwards that use viscous fans and is fact listed by SE for nearly all their nissan's as gaining a few bhp. so to the question in hand, easy enough to do, either source your own fans to fit or buy the kit from Z1 motorsports ( i did) then ideally buy an electronic activation system for switching on a pre set temp if needed, i got mine from wizard products in the US, use it with the supplied temp sensor which am mounting in the top inlet pipe and yer done, once you remove the old viscous jobbie of course :)

Done this years ago in my old silvia and S13 and worked a treat, seldom did the elecy fan activate and car never over heated.

cool thanks for the advice , any other ideas of making my cooling system more efficient?? i know i can replace my stock intercoolers and rad but any other ideas

Yes use a couple of bottles of Redline water wetter and high quality anti freeze.

 

An alternative rad option is a used UK manual rad as this is the nismo one! Improve your auto box cooling by fitting a separate cooler and fit a larger engine oil cooler if your car is an import!

I have an electric fan on mine, seems to run cooler but I can not prove it.

 

Other ways of gettting the cooling better.

 

Bonnet vents and IC vents. removing the windscreen strip so that the air flows across the engine.

 

Clearing out the water ways if they are over flashes.

 

Aqua mist etc but obviously these are not going to be able to run constatly.

An alternative rad option is a used UK manual rad as this is the nismo one!

 

 

You sure on this one mark ? i've always believed the Euro spec was the nismo jobbie, the one's suplied to the Germans due to their unlimited speeds. happy to be corrected if wrong though.

I have read a lot about this from the American forums. Under normal conditions they are fine, but on hotter days they just cant push enough air to cool the rad down.

If it just a bit more cooling you are after, it is quite a straight forward job to add an extra switch via an isolation relay to the air con fan and run that as well as the viscous fan, seen this done on a few zeds, mainly for hard summer use.

Karl the viscous set you have is more than capable of dealing with the power you are gonna put out , your gonna have the water bypass which makes the system more efficient anyway and probably the best thing you could do imho would be to rip the air conn condensor out as this will make airflow to the rad much better , down side is you lose your air con
