Hey I got a crx with a obd-2 b16a bottom block, a type r head and a b16a1 intake manifold.... now I am thinking about making my car obd-2... a friend gave me a dizzy from a 00 si and i got a gsr ecu.... do all I have to do is order a harness? I was thinkng of ordering 1 from one of this sites sponsers SVE... what do you guys think... and will I need a new header? I have a header from a 90 integra on it now.... thanks a lot
