ive heard anything over 6psi, and your asking for trouble. yes tuning makes a huge difference but even then your reducing te engines reliability by quite a bit.
And before some guys on here with charged s52's come blasting about how theyve had their blown for years. Yes it also depends on how you drive it, if your a conservative driver that likes to play around once in a while, your ok. But if you are constantly beating on it, youll do some damage. Id recommend at least getting a commetic head gasket and arp head studs!
just my 2cents

BlownM3 on here has been blown for a while, runs higher PSI than the setup was designed, has it tuned for each change he makes and drives the living piss out of it. In fact, he twisted a driveshaft last weekend..

I only ran it for a few days, its way too much for the streets. I turned it back down to 12psi for daily. I mean wheel spin in 3rd ftw!
At 18psi i would say i was very close to 500rwhp.
Im on a custom tune, no pics of yet.
Its an
m52
apr2000
head studs
mls head gasket
spa manifold
gt35r
550cc injectors
custom charge piping/downpipe exhaust
i did all the work my self.
