Ive searched but couldnt find exactly what i was looking for. How much boost can a stock block GSR handle reliably?

 

all depends on the size of the turbo, psi doesnt mean anything without a turbo size and such.....to give you an idea though ive heard people running 12 pounds on stock gsr motors with a very good tune.....but for a daily driver i wouldnt push more than 1/2 bar

 

Psi doesn't really mean anything. It's how much horsepower the motor can handle.

 

I will rephrase the question. I have a t04e 57trim, .63a/r exhaust and .50 compressor side turbo. I would like to make around 300whp. or run around 10lbs of boost with this turbo. Would this be too much to ask for on a stock gsr block?

 

with a good tune 300whp is not gonna be a problem. ive been running my 270whp gsr for a year with no problems.

 

I would say no more than 1 bar (14.5psi) reliably on a stock motor if that. Maybe take alittle with nice tuning
