Last I checked, they don't make billet camshafts for Altimas, so your only option is to have someone do a regrind, in which case you're going to have questionable quality. And, as you mentioned, a rougher idle. And if you're going to ask about using 240SX cams, since they use the same KA24 block, unfortunately the 240 cams have an extra lobe or something - they're different, anyway. Sorry to be the bearer of bad tidings.

Not sure about that. The cams for the ka24de motor should work for any ka24de motor. There shouldn't be a difference between the actual cam of the 240 sx and the altima cam.

However like he said the only cams out there for the motor are jwt or gude. I know jwt are regrinds and I don't doubt that they are good quality, however regrinds will be a little harder to install and reference correctly.

I don't know enough about the gude cams to give info on them

no...
the cams for the 240sx are different and JWT does make cams for the 240 KA24....
the stupid Altima's cams dirrectly run the stupid distributor or some shyt.....

the 240sx CAN use the Atlys exhaust side cam because it stay open a lil longer than the 240's i believe.....
the 240 can also use the Atly's lower compression pistons for turboing..

interesting... can you elaborate more on that
Well, it's the other way around - the distributor on the Alty is driven directly by the back end of the exhaust camshaft. On the 240sx, it is at the other end of the engine, and at a right angle to the cam. See:
