I just bought a new G35 coupe. I want to boost the horsepower a little without affecting the warranty of course. I have heard about some sort of ground wire kit that gives a good boost. Where in Sac can I get something like that installed? Any other little things to do without messing up the warranty? Thanks. -SacOldGuy

check with a shop called motorsport dynamics. www.motdyn.com

there's also a shop called S-Squared that can do some of the more high end stuff like supercharger kits and the like. www.ss-ms.com
