Hey Brandy and all those who responded to my post.<br>I actually want to install cams and pulleys, but how much of a mechanic do I have to be? I ordered a brand new pulley set and sold it after 6 months without ever attempting to install it 'cause it looked pretty difficult to put on. I'll attempt to put 'em on if they really help, but I've got a d16z engine or something like that and don't plan to drop an engine. Is it still worth doing it? Will changing my plugs and wires make my car faster? That's something I can do and will do. Any suggestions on manufacturers? Thanks....&lt;&gt;&lt;
