So, how much boost can the stock turbo be pushed to...

[Natheo]

On a completely stock GN without doing any damage? Or maybe even some cheaper mods. 15psi is stock right? what kind of gain would you see if you bumped it up to, say, 17 psi?

 

[salvageV6]

Roughly 10 horsepower per psi.

You can push the stocker to about 22psi. max. on a stock car.

Higher octane level required.

Increased timing also adds to the horsepower levels.

so you think 17 or 18 would be really safe? i dont want to blow **** up, just make it a touch faster. wow, i dont even have the damn thing yet.

You need an adjustable wastegate actuator on a stocker to raise the boost or an aftermarket chip that has it programmed in it.

YOU NEED INCREASED OCTANE ALSO: 100 octane unleaded at a minimum to increase boost and timing to make more power.

Or an alcohol injection kit.

And you need to check the fuel delivery system first also to increase power, fuel pump, filter, hot wire kit, adjustable fuel pressure regulator.

Learn to drive the car on the stock boost first before trying to make more power, it will give you plenty of time to upgraded the needed things that are REQUIRED first before you can make the power.

Yes, listen to salvage. Exactly what he said.

I ran my stock turbo up to 23 psi once with 110 leaded race gas and a low timing chip...but 20-22 psi is the norm (safe range) for max psi on the stocker...
