I know that a company local to me sells an aftermarket NX2k and SE-R radiator, but I'm not sure of the brand name. (PM civicsRslow - he's got one on his SE-R and has had no problems. He might recall the name of the company). If you're just looking for a better radiator then you have you could always use an NX2k radiator. Water Wetter is also a good way to reduce temps.
