I'm going to be upgrading my radiator here soon with a 36mm one, and was wondering which fans are you other Vortech guys are running? My oem fans are calling it quits so, should I replace them with the OEM ones again or is there a better option out there?

 

mishimoto, or the ebay knockoffs are pretty much as good, the yare easy to change and cheap.

 

Why upgrade the radiator? Are your temps running high? If not, wouldnt it be cheaper just to replace your OEM fans?

I was going to upgrade my radiator but my temps never pass 210F and when they do my fans kick in dropping my temps back to 190F.

 

I need to replace the radiator(leaks) and it just so happens that the fans are calling it quits too. What I need is a fan shroud that accomidates the thicker radiator and the vortech kit. I'm looking for recommendations as to what some other Vortech guys are running.

 

I see. I was going to go with a Koyo 36mm and GTM Shroud for the Vortec. Its pricey but no modifications are required. But im in a G not sure on the specs for a Z. I know on the G the OEM shroud will need slight modifications.

 

I managed to fit the biggest Koyo in my car; Koyo 52mm, but I ended having to get aftermarket slims fans (in my case I got the Flex-a-lite 420, 2500 cfm)...

that's about as big as you can go, I doubt you can fit the PWR 56mm radiator with ANY fan setup out there...but keep in my this is for a built engine setup running over 500whp...

That being said, if you're still running in ~450whp on your stock blockyou should by fine with the 36mm setup, unless you track a lot...
