I was one of the two older Z's that showed up this weekend. I come out periodically with the HNE guys. I'm also a member of the Z club of Houston, but most of those guys don't drive S30's. If they own them, they are probably non-running. The other guys have S30's in such great shape the only modifications they are interested in are what kind of wax to put on next. Very few daily drivers. We are mostly out of luck. Me and the other Z guy are near Tomball. Not too terribly far from you, anyway. Maybe we could get together sometime this week / weekend. I would love to check out tweaked L28. Might give me some ideas for my future setup (that's on an engine mount in my garage).
The other Z is a 72' with triple mikuni's and is pretty much a track setup like yours. Vintage track setup, anyway.
