- Mon Apr 15, 2013 2:53 pm #330621 well see the problem is i didnt know i didnt catch they were switched till a a month after ive been testing it and driving it a lil will it cause any problems other wise like for example the car will not hit red line at all n doesnt seem to run like a b18 should

hook them both up and start the car. if the car runs like shit and the check engine light is on then they are backwards.

- Tue Apr 16, 2013 4:44 am #330642 I'd say its probably fine, people confuse them all the time and have no problems once they fix it. I'm actually running my EBC boost solenoid off the wires that used to go to the purge valve.
