I've always thought of cams as being a last resort , when you can't get any more power out of everything else. The stock cams in the Z31 are 252 from the factory , and that's pretty healthy for a stock cam. You'll start to have driveability issues if you go beyond that. 265/272 cams are great for high rpm power , but you'll lose a lot of accessory vacuum power , and brake booster power.
What are your currrent mods and future plans for the car? Just throwing a bigger cam in a car isn't going to net you a whole bunch of Hp , some yes , but there are other things that need to go with it.
The stock intake mani either needs to be extrude honed (Or if anyone knows a better process) or the Pathfinder intake needs to be installed for the higher airflow , bigger TB , bigger turbo , intercooler , all that stuff needs to be done before you can really start taking full advantage of a bigger cam.
I also don't know how far along you are with the car , you may be a lot farther along than I am guessing.

well so far i am running 12 psi, spectre air filter,no cat no muffler, well cat is hollow. i am trying to figure out if it would be better to go with aquamist, FMIC, or both. i am just trying to get pricing on upgrades so i know a rough ball park of what i need to save.

The cams I recomeded will not hurt bottom end.

No problem , I'm used to kids going out and buying huge cams for their otherwise stock engines and then complaining about how it's undriveable after that....

Aquamist is fairly cheap to piece together , FMIC is a bit harder and moe expensive. On the other hand , water being in limited quantity , gotta watch the level and make sure you have enough , or if you run out you might go to boost and blow up your engine...(detonation)

while on the subject of cams I have found dual cams for my engine but don't know what to do with the computer part should I get a standalone or what??? help would be appreciated. I'm not talking help as in telling me to get a turbo engine.
Well you would need new heads and your ECU wouldn't be able to handle it and your not going to get that much more HP AND it'll be a lot more expensive than it's worth. Keep with the SOHC
