I need a water pump for a 16V 94 m reg. Is it the one off an Rsi o r would a Williams or 1.8 19 one fit? I also have a superchips ecu, but need a new carrier for it I think to solder to my existing ecu. Any ideas where I could get one, or is it superchips only? Is there a way to take the chipped ph2 ecu and make it work in my car? Thanks
