Hey everyone... And yes i am thinking of making my rex obd-2... i was looking for an ond-0 ecu and dizzy but a friend of mine gave me a dizzy from an 00 si with a masd cap for free!! and my other friend has a GSR ecu he will sell me for cheap... So I am thinking of ordering a harness from boomslang or SVE... is this all I would need to convert it? Just the ecu conversion harness? Also how about the header... do I need to change it or anything? I have a 90 teg header on it... thanks a lot guys!
