We can make them fit on the 06...no problem. 
Mike is correct about the S2 cam. Incredibly close performance numbers, and the engines will idle smoothly without an idle bump.

In my state of Az for example your vehicle will either be tail pipe tested or the ECU will be checked for error codes and a visual for cats. If you pass this test your home free unless they find engine has been modtified. If they do the only way your going to get passed is if the mod has CARB approval. The exact requirements for emissions testing state by state can be researched on the net.
Passing emmission is not a big deal. All states require that OBII codes are clear to pass emissions, and that could be a gas cap. But a TT kit (not one pushing 600hp) with cats should pass emissions, and if you had it on your car in AZ you wouldn't risk having your car impounded and have to take it off.
Emissions and CARB are not the same thing. CARB is a BS board that makes money off making things legal. It's good in theory but not so much in application.

Beer: I think Gary Evans was trying to say that emissions laws vary from state to state. But CARB is considered the gold standard. If something is CARB certified, it should have no trouble passing in other states. All of us..myself included...are speaking mostly out of common sense and speculation. Few people have the time or inclination to become emmissions law experts, as there are pages and pages of really boring rules on this stuff.

it matches right up there is really nothing you have to do that diffrent a couple of hoses apushed to the side and your windshield washer tank is not mounted like it is for the 03-04 but everthing else is about the same other then the ecu part.
are the s2 cams only for turbo? I have a vortech with 3.12 pulley and just want to get some extra hp/tq without upgrading to the smaller pulley. How much extra pw are we talkng about and does it help with lo end? Also, will u need to upgrade the springs or having stock rev limit is fine?

the S2 cams are a n/a or boost turbo, safe for both. the S2's are the most conservative cams JWT makes, but still mkae within a few whp of the S1s, without the diminished idle quality. The C2's are the only JWT's which you need valvesprings for.

JWT and FP always recommend upgrading the valve springs when doing camshafts. You can use the stock springs, but since the labor is already very costly, it is best to upgrade the springs as well. Given their relatively low cost, its a good idea.

just required for C2s. but I'll agree with Sharif, for the labor involved, it's like $230 for valvesprings........its worth it.

Pulling the Valves, replacing the springs and setting the stack to spec is a big process. Trying to get the stack height correct is not an easy task. I just did it and it took me 9 hours to do all of them inorder to get them within spec.
So prepare to fork out A LOT for the valve springs and restack labor.

Once you have done it a few times, and with the proper tools, it really isnt too terribly bad. But the cost of this is included in our cam change labor, so the customer really isnt paying anything more to swap the springs. Some shops might be different.And 9 times out of 10, the valve clearances are still within spec. If not...a little bit of shuffling usually solves the issue.
