gerrardq Posted September 1, 2017 Share Posted September 1, 2017 Hi all, Has anyone had any bad experiences with ebay aluminium radiators? is there a better product? I will be converting my Auto L26 to a Manual L28 with a fair bit of internal work. (Pic is what was in the Z) Any guidance would be appreciated. Cheers Quote Link to comment Share on other sites More sharing options...
Cozza Posted September 1, 2017 Share Posted September 1, 2017 Ive got no experience with ally rads but, why don't you want to get the original rad reco'd? They look heeeaaaappps better in my opinion. And, works fine on my car. Copper is a much better heat conductor than ally. Cheers Mick gav240z 1 Quote Link to comment Share on other sites More sharing options...
44014 Posted September 1, 2017 Share Posted September 1, 2017 I bought a eBay one but came from America. It's eagle brand I had them make me a 4 core when the dollar was good. Was sub $400 aud delivered. Quote Link to comment Share on other sites More sharing options...

Cheers Mick I would say that having an original reconditioned would probably cost at least as much as a new alloy radiator. Copper and aluminium have roughly the same heat conductance (copper is slightly better) however Ally radiates heat better. But yes. I reckon the orig radiators look far better than the typical big shiny ally ones! Andrew Quote Link to comment Share on other sites More sharing options...
gilltech Posted September 2, 2017 Share Posted September 2, 2017 Do any of the alloy ones I see on eBay have attachment points for a shroud? They don't appear to. Quote Link to comment Share on other sites More sharing options...
Administrators gav240z Posted September 2, 2017 Administrators Share Posted September 2, 2017 Recore the original to 3 core, looks 100x better in an S30Z engine bay in my humble opinion. Quote Link to comment Share on other sites More sharing options...
Moderators PB260Z Posted September 2, 2017 Moderators Share Posted September 2, 2017 Hi I have an ebay radiator in my L28 powered bus. Haven't had a problem, but the mounting holes were slightly off. It does have mounts for a shroud but I did not use them. There seems to be two designs and prices, I went with the slightly more expensve one.

Brabham Posted September 2, 2017 Share Posted September 2, 2017 Does your current one leak? Give it a clean and put it back in if it holds water. A recore would be around $500 but originals look much better than ally. That looks like a 240Z auto radiator to me. Quote Link to comment Share on other sites More sharing options...
Cozza Posted September 2, 2017 Share Posted September 2, 2017 Copper and aluminium have roughly the same heat conductance (copper is slightly better) Difference of close to 50% I think. Here's a good website. Check the k values. http://www.engineeringtoolbox.com/thermal-conductivity-metals-d_858.html Quote Link to comment Share on other sites More sharing options...
CBR Jeff Posted September 2, 2017 Share Posted September 2, 2017 (edited) Yep copper has a much better heat transfer rate than aluminium but heat transfer is not the only factor that should be taken into consideration. Both an original and an aluminium radiator will work both look good in their own way and both will fail if you don't do the right thing. The main difference is the weight of the copper in comparison to the aluminium. An aluminium radiator allows the builder to construct a larger heat transfer surface with much less weight. At the end of the day it's personal choice. There are quite a few good quality manufacturers in australia of these product although some what more expensive than the eBay imports. I purchased an Australian manufacturerd unit for my car, although I suspect mutch of the componentry is imported.

KatoKid Posted September 3, 2017 Share Posted September 3, 2017 I looked at PWR but they wanted $1200 ! Went for the eBay special out of the US, with fans and shroud for $320. If it cant do the job then I can trade up but cant help but feel you're paying a premium for the PWR name. Quote Link to comment Share on other sites More sharing options...
