I was considering the Skunk2 radiator. since its right about in the price range I was looking for. I have learned that ebay is not the place to go for parts. I have other things to accomplish first though like getting the car through emissions this month on the stock ecu while running 440cc injectors and finding some way to prevent the supercharger from making boost so it doesn't throw itself into limp mode.
I had the eBay one laying around but like u said. NEVER EVER go to eBay for parts. I had a Jackson sc with 440's on a jdm gsr and never came close to passing. I ended up putting the stock motor back in to pass. Put the motor up for sale to test waters and someone offered me a deal I couldn't refuse. Come to find out the stock p72 was fried causing it to dump gas into the engine. Do you have a smog guy? Some dyno time and some tuning I'm sure you can do it. With that said, its gonna be a hell of an adventure.
