I believe that the cats or something in the exhaust is better on the 02+ which enabled a better cam and more power. Which is not a big deal if he is planning on modding it anyway. But some of the 01 (not all) were recalled because they burned oil and they had to be reringed, that is why most people shy away from the 01's. If he buys a 01 he needs to check it out to see if it is burning oil or if it has been fixed under recall.

The 02 has a bigger cam with .550 lift. Bigger intake opening. Descreened MAF. No pup cats. 02-04 had titauim exhaust. Not sure for 01. 04 had better shocks. I'm sure there is something else I am forgetting.

Guys, there is a lot of mis information in this thread!!!
The blocks and heads were the SAME!
The intake valves on the 02-04 were hollow, sodium filled
The 01s had blue springs ( like the hotcam kit)
The 02s had yellow springs
03s+ had metal colored springs with an orange stripe.
The 01s had a smaller cam, 02s had a larger cam and a better "tune" to get to the 405 ( its the same PCM, they just changed the tune)
There were no pup cats on any of the Zs
The manifolds were the same
They all had Ti catbacks
01s had a ring issue, and had a re-ring recall on them
01s did not have the HUD
Mid 03 and all 04 had top mount, c6 style fuel systems, C6 water pumps, battery systems, ect.
This thread is old, but I gotta look out for Mike C.
