What's a good cam for an auto 90/300ZXTT. Im looking for good mid range power. I'm taking the heads off for port & polish, new valves, spring etc... also have AMZ ztage II turbo with supporting mods exhaust, injector etc.... egine bottom end is still stock with 86k.

 

depends on how much you want to spend. JWT has their mild set at around 500 bucks, and they have the 400s and 500s at 950, and then tomei, and others are more expensive as well
JWTs mild and 400 cams will probably be the cheapest and very streetable
JWT's mild set is 1200 with their heavy duty springs, new lifters, sprocket adaptor, and a 400 core charge

 

You could also consider Z1's cams. They're pretty similar to JWT's, but a little less expensive.
