How much Boost is safe on a stock engine.
With the rebuilt motor you can run 23.4568psi. If you accidentally run 24psi, even for a moment the welds on your intake manifold will come apart.
Dual NOS bottles should only be used when compound charging, one before each compressor wheel. Bonus - when you're compound charging, you get four times the boost instead of twice the boost!

"How much boost can it handle" without further details is one of the dumbest questions ever. In order to be able to make any sort of estimation we would need to know all the details. You changed all the metals? What kind of rods? What sort of turbo/manifold/exhaust/etc? Engine management? Who is tuning it?
It is known that, on average, stock rods tend to fail somewhere around 250 wtq assuming good tune and such. if the boost comes on hard and soon it is more likely to break than boost onset softer and later.

i didnt replaced rods because my main point wasnt based on Turbo. My engine was suffering of low compression in 3 and 4, so i replaced piston rings and bearings (I have pictures of the complete work).
From what I have seen and read 12 psi is completely fine on a stock engine and really if you want anymore power you have to get forged pistons and rods. Can a stock engine handle like 15 psi? If it can how well can it handle it. If you run 8 or 12 psi usually then boost up to 15 sometimes would it hurt?
what about no tune. what boost pressure can i run with no tune till i get ecu ?
