    Well you asked what the best option is. And as @swinks said thicker doesnt mean better. A thinner copper rad will outperform a thicker alloy one but it comes at a cost. As does any quality performance part

    That's an interesting material I had not considered copper for car rads.
    Very interesting when you look at all the old 1920 brass cars they had copper rads. A copper was available easily available. I know aluminium was not available in that era but there must have been a decision at some point to go for a steel rad over copper just based on a price point. And people never looked back.

    Just shows you new ideas are not always best

    Bye for Now!

    Thank you Adam, very well spoken
    Copper Koyo rads I've seen on Yahoo were price tagged 300 - 400 GBP before shipping and customs. IMO, well worth money for what they offer you in terms of quality and efficiency. Myself I did consider to replace my 50mm thick Evo 8 one with proper copper Koyo one, but in the end I swapped vehicle
    Ex: Galant VR4
    Running 268 HP ATW and 443 Nm torque at 0.9 bar
    Now: Lancer Evolution 8 FQ-300
    Running 325 HP ATW and 510 Nm torque at 1.6 bar

    I wasnt saying a koyo wasnt worth it. I looked on rhdjapan and they wanted 700 for the rad. I can get one for 300 but its got to be modded so even if it goes wrong i have no comeback but 300 is worth the extra i was just weighting up my options. So went with 52mm alloy rad as im not sure on fit + it came with fans ect and if it does fail ive still got enough left to get another.
    The more i can save the more parts i can buy.
    Like said ive had koyos before so i know there good i just wanted to know my options. As long as the one i got fits and works ive saved myself 150+ and have that to spend on other bits.

    Thinking about changing my radiator next to an evo 4-6 one, Ive read a few threads on here already but I'm hoping someone can confirm a couple things. What top hose will I need to use and will I also need new fans?
