How would cam gears help OBD-II engines? I thought you can't advance/retard timing on these engines since ALL timing is determined by the ECU? A cheap way to advance/retard timing on pre-OBD engines was to rotate the distributor cap. :-D

For power, I'd get yourself maybe some custom exhaust piping, pulleys, camSHAFT, and some V-AFC or better yet AEM EMS tuning. Intakes and headers don't give you as much power/$ you spend on the Accord. Unless, if you buy them used or fake for REAL cheap. Web makes some camshafts but I'd stay away from Bullfrog or Gude. They're not as reputable as Web. There may be others but they'll most likely be custom jobs costing you lots of $$$.

Also, port & polishing the head will give you good gains as well as boring the throttle body and port-matching it with the intake manifold. The key is to allow the engine to breathe in and out better and tune the ECU. You don't have to worry about fuel delivery since the stock system will suffice until you go extreme. Same for ignition except that platinum plugs aren't the best for the job so should be replaced for copper or iridium.
