I'm not trying to be a dick rockstar, but instead of posting these questions search for the answer. A lot of the things you ask have been brought up recently and are probably within 2 or 3 pages of the first page, honestly.

dont go pistons. its not needed, our high compression is what makes our power.

go with cams if anything, regrinds+ a sick cam tune is a easy 20-30 WHP!

Becareful though, cause if you go with NA cams, and you decide later that you want to do with FI, I read that the cams will need to be changed for that application.

It would end up costing quite a bit cause good cams aren't cheap. do it right the first time though.

mmm i dont know how enterily true this is...but i know for the LNF the LE5 uses the same exhaust cam...might be for the intake cam...but again i am not sure about huge differences in cams for N/A or F/I

Yes the stock cams are the same, usually when people go with an N/A build the aggressive cam used wouldn't work properly for a Forced Induction build... Or so I've read. Its on these forums, maybe in the performance modifications forum.

Since you are going turbo I would do some more research before purchasing anything with the cams, this way you don't have to re-do anything alter on.... Just incase.

ttr says that a stage 2 or 3 n/a cam puts helps more then a turbo grind cam does (when turboing a 2.2) i just dont see why unless maybe you degreed the cams a lil different for more efficient overlap.... ?

The stage 2 and stage 3 comp cams are more aggressive than the "turbo grind". The stage 2 and stage 3 work well with turbo also, you may need a set of adjustable cam gears to change the over lap (exhaust to intake cam) I have the stage 3 grind on my cavalier ecotec/turbo, however I have a complete aftermarket ECU (Electromotive TEC3)

Wiseco makes a drop in replacement set in both dished and domed versions iirc. Check the soltice forums.

Rods can be obtained through Crower that maintain the stock pin diameter.

For a turbo build you can swap the exhaust cam from an LNF, the intake cam won't fit and after looking at cam specs, you probably wouldn't want to anyway.

According to Witt, and he knows his ****, you can probably use your new cams with the turbo you choose. Or at least that is how I interpretted what he has said.

No. Then again you don't need to change anything if you don't want to.

Back to your original question, this place has a decent online reputation and sells what you need. A Google search could probably find others.
