Eventually you should built the bottom end of the engine. (Forged Rods and Pistons) the factory crankshaft is fairly stout.

This will serve as a safety net and you can run more boost.

As for now 8lbs is ok, and as long as you have a good tune and drive semi-conservatively it should last you a while.

I just ordered stage 3 patriot heads and Cushmans stage 3 blower cams. Waiting for them to come and I will install them next month sometime. I wouldn't suggest running the same combo with only a p1-sc. You should go for a nice stage 2 head and cushmans stage 2 blower cams. Cushmans has a great deal on heads and cams.

I would not be the first to suggest patriot heads, the only reason I got them is because a guy in my town does great work on them and can improve the flow by 20cfm both intake and exhaust.
