Radiator oem or upgrade on racecar?

[Jimmi The Kid]

I have allways thought a upgrade alloy radiator are the best out there. But my friend just showed the opposite. He have a drag Starlet, fitted with a 600hp 4A-GTE and a Civic radiator. First a china made thick and heavy radiator, it ran too hot. Then he bought a Mishimoto Civic radiator with no difference at all, still too hot. Now he fitted a unoriginal OEM radiator to a fraction of price and problem solved

I'm building my race/rallycar, and wondering if you guys had any similar problems with upgrade radiators? I'm very confused what I should buy?

Never had any problems with cheap alloy radiators they always delivered what they promised: better cooling
Not sure what went wrong on your buddys car.

Mine is double row oem radiator, which you can probably let do at radiator shop
Never had any problems and car was on circuit for 4 hours 2 weeks ago.

Double row copper is the way to go if you want serious cooling and weight. No complaints on my Koyo rad more then that it didn't come with a cap.

Those always come with OEM cap.

If yours didn't contact the company you purchased the radiator from. As a Koyorad dealer i know some stuff =)
