Suggested rev limit for S1's on stock turbo?

I'm hoping Greg can chime in here, what is the suggested rev limit or the max for S1's on the stock turbo? I just want to know where it should be at without putting the engine at any risk. i know power falls off anways, but would like to know for my own peace of mind.

Thanks

7500-7800 on the stock valve springs and the S1. when you dyno the car you will notice its probably a good idea to shift around 7k or just over it, there is more ussuable power if you shift earlier than later on the stock turbo even with cams.

So if I upgraded the turbo and ran lets say a green, running the S1's to 8k wouldnt be safe on stock valve springs? What upgrade path would you recommend at the minimum to be safe?

that should be fine to do, however to be safe i would throw some single spring upgraded springs in her and never worry about it again.
