if your pcv hasn't been done yet, i'd recommend doing it as well, it's easier with the alternator off. Also if you're yanking the disa valve, grab an aftermarket o-ring for it (rocket seals sell them i think, do a google search for the exact part), they often leak and cause fuel trims to go south. FWIW my car picked up a good bit of mid-range after doing the vanos rebuild.
