Mitch, how much did Wizard run you on that radiator? Im curious to using a used Porsche center rad, or just getting a new one made. Im looking to do a conversion myself and want to try and replicate the 986 cooling system. I know the PVX build did custom rad's but they weren't cheap as i'd like. Im told they work well though:
