Check local craigslist.... there's occasionally some OK stuff on there. I saw an ad for an S-Tune exhaust yesterday. Seems to be gone today but another ad that has one in a big list of parts. Might be same guy, not sure.

And, as Travlee said, post up your WTBs in the marketplace, might catch someone parting out or selling parts from their sold car.

S'far as tuning, best dyno/tuner for Zs in the area is Z Car Garage.

 

It's a few hours North of you, but SacCityAuto in Sacramento will usually have some good parts. I got a very reasonably priced, slightly damaged Nismo CAI from them a couple years back. Plus, if you're willing to drive another hour North, you'll be at Thunderhill!

 

Oh yeah, good 'un. There's actually three Nissan "recyclers" up on, appropriately enough, Recycle Road in Rancho Cordova. SacCityAuto and two others. If you need fenders/body parts, engines, transmissions, etc. Look these guys up. Their inventories change all the time but Zs are pretty plentiful thanks to the firm of Dugan & Diphooner.

I've never used them but for older cars I've sourced various hard parts from the Volvo and the Mercedes specialists up there. And yes, they do ship (or at least used to).
