every time i'm down there, they are working on boosting someone's G or Z. they've done some amazing work, including building a G sedan with JWT TT kit. one problem with them - they are very busy, and anything takes a long time for them to do.

Plenty of comments by other Z owners at Bay Area Z Club and other forums. I will let them tell it. http://www.300zxclub.com/showthread.php?t=89027

Don't get me wrong. There are alot of friends and workers that like ZCG. But on the flip side I have heard others who say differently. There's always someone that works or friends with ZCG on all of the forums, so I just becareful of what I post. I don't want to offend anyone on the open forum.

I could not recommend another Z/G shop. I have a friend at Nissan that is takes care of my cars.

Try this like if it works. It's a Z guide:
