Really if the car was made with certain emissions controls that you leave them be... like EGR or the catalyst (airpump not so much... It's really not doing THAT much for emissions, but then again, it's not doing much to rob power either). The main thing is that if you change the emissions on the car you'll change the fuel economy. If you block off the EGR then the combustion temps will be higher during an emission test so you could fail (theoretically). Don't advance the timing to much unless you are running premium or race fuel. That will kill power and economy. It's best to stay within the BTDC of the emissions sticker. If you don't like in an emissions county then you'll take the head off, get it rough ported and gasket matched AND milled .020 and get bigger lb injectors (or larger CFM carb) and a standalone ignition system. Gasket match the intake to the head, put a header with 2 1/2 inch straight pipe into a performance muffler and dump it before the rear axle. Get a NISMO cam, adjustable cam gear, have the crank knife edged and turned down for less weight and balance it within 1/16th of a gram, lightened flywheel, 4 puck clutch, brace the chassis for rigidity, and get a 5 point harness.

If all above cost to much, then deal with what you got
