Ok guys. Started up the new motor yesterday. IM having what seems to be some MAJOR problems. My spark plugs are all different colors on the tips. The passenger side spark plugs BOTH have White tips and the Driver's side plugs both have BLACK tips. Obviously my drivers side is WAY too rich and my Passenger side is WAY too lean. Im pretty positive that my timing belt is fine. I am not running any engine manegment. just a JC sports Torque Chip 2. I am also running a Parrellel Fuel delivery Setup. The motor setup i am running is a Phase 1 EJ22 Turbo Block with my SOHC EJ25 heads. I am not the only one to have done this type of swap, but i have not heard of any problems like this though. Could the lower 8:1 compression be what is casuing my car to be so out of whack? Does anyone know the part number for the timing belt that i should be using from a 2000 2.5 RS? Also which mark on the crank sproket shoud i be lining up with? how many teeth should there be between the crank sprocket and Cam sprockets? If ANYONE KNOWS i would apprecite help! THANK YOU ALL SO MUCH! My car SOUNDS like it is misfiring. and the TIMING SOUNDS off.
