Ok guys ive done a little searching and ive come to find:

Koyo 2 Layer aluminum $300
Koyo Copper series $200
Gp Sports 2 Layer S type $275

Basically i have a stock sohc radiator on my sr now and its all corroded and needs to go...Supposedly the copper one cools better but weighs more??? What would yall recommend i go with, i dont need anything to amazing because i think any of these will do a lot better than what i have, so do u think the copper one would b good enough or what are your suggestions...

 

Well... thas all you bro. You've done your best three, now pick one based on ur asthetic style/functionality... ish like that. It's ur ride bro.

If ur in an area where it's extra crispy in summers go with the copper. Othawise alum will do and save a couple of lbs to boot.

 

Yea i was just making sure what i heard about the coppers is true...Yea the summers are hot here, high 90's low 100's for a steady 4 months...

 

Just lettin everyone know i ordered the copper series, and if anyone cares ill update on how it performs..

 

Im getting a new thermostat also, any recommendations? Is the oem replacement good enough or is the nismo one that lowers the temp really worth the money?

 

Nismo.

If not ..get the Billion Thermostat. Uber JDM.

cause you know u want tooooo...

 

Hey question, Im in search of a good aluminum radiator that won't crack for my ka24e. Yes a SOHC. My stock calsonic cracked then my new radiator cracked as well. Is there any hope for my ka? Thanks

 

Let us know how the Copper Koyo fits and performs, Im interested in seeing how it is also. BTW where did you order it from?

 

Yea i will, i ordered it from enjukuracing.com and i ordered my nismo thermo. from courtesynissanparts.com...Ill update when its all in..

 

Ok, heres some pics if anyone wants to see, the parts will go in monday though so ill update one more time..

 

Well, got everything put in....car still overheats...so i guess im about to try changing the water pump tomorrow...startin to get really with all this, hopefully that will solve the problem..
