First of NAGoer Is an OG when it comes 2 the 5th gen accord, the amount of money this guy told he he dumped in his car is CRAZY... 4 times more than anyone has ever spent so i think he knos a little bit
2ndly, there ARE aluminum radiators made for our cars... JVT makes em and so does a lot of other companies. If they make superchargers for the v6, then i dont think they would skimp on other performance parts especially like the cooling system. I just searched ebay and found like 30 results. And plus if they dont, im pretty sure you can put the 6th gen 4cyl radiator or the acura TL radiator which I KNOW FOR A FACT they do make... and they are NOT $400, they are all under 200 so i think u would be good
another option you have is to get fab up a radiator cover for your car. I'm pretty sure if you do it through TAS R&D dept or any other company, they would be more than willing to help because once they have a solid radiator cover, it lets them create more to sell to guys like us whom like me have been wanting to buy for over a year now
Sorry bro for all the hassle here, but really search, u have multiple options. I hope to see your car again at other meets next year
