hi guys and gals, i own a nissan 200sx s14a 2.0l turbo, im looking at putting a dump valve on it, my question is , am i right in saying that the car has a recirculation valve on it, located behind the battery under the fuse box, the next question is, if it is a recirculation valve, i was looking at ordering myself a forge splitter valve, is this ok and will it fit my car and run fine with no remaps or tuning ,?? cheers
