How much boost pressure can a built VQ37VHR withstand?

I am running 13PSI peak (settles in around 12.5 under most scenarios). I had to upgrade to the CJM return fuel system to be able to support fueling at that

I am running 13PSI peak (settles in around 12.5 under most scenarios). I had to upgrade to the CJM return fuel system to be able to support fueling at that boost (the stock system would drop ~15psi under boost). Car has been running great. Nissan did right with these engines in my book.
