I personally wouldn't go over 8lbs on stock internals with a stage 2. That may be a tad conservative, but I don't feel like dishing out another 2-3 thousand or so to fix a blown engine. (Of course I don't have a turbo yet, but if I did, it wouldn't see over 8 lbs):)

I wouldn't worry as much about the internals being stock...ours should be good for up to about 12-14 lbs. of boost. What you need to worry about more is your fuel system. Our injectors can't flow enough for more than 10 Lbs. and i think that is even pushing it...so yeah, 8 is where i feel safe with mine being.

You know, seeing how the ECU can control up to 310cc injectors, if someone just wanted a little more than the standard 8psi they could swap in a set of 310cc and run 12psi. I believe it would be safe as long as the a/f stayed constant and didnt lean out. Watch those gauges!

I would have to say for all people out there, unless you are able to monitor your EGT and/or Air/Fuel ratio, I would keep it at a safe 8psi (Intercooled). It never hurts to be on the safe side Once you are confortable with your setup, and are sure your getting enough fuel (EGT and O2 readings) You can probably start playng aorund a little bit. No tow motors are the same, the only thing you can make sure of is that your getting anough fuel. And EGT and/or Air/fuel gauge is the only real way for you to know your getting enough fuel!
Aside from that, I haven't heard of anyone running 310cc injectors on a stock bottom end and running 12psi. 13-14 psi mgiht even be possible as long as detonation could be controlled (J & S Safeguard Knock Sensor) I don't see a problem doing it, I think it would be a viable solution for boost hungry people who are not ready to build te bottom end yet.
