i need to know what the stock redline for the 180sx s13 black top sr20det engine is, thats what i have in my garage and im getting JUN single valve springs and i have eagle h-beam rods.

i was under the impression that the sr20det redline is 7200 rpm but i just heard otherwise,

this is pretty important since i am raising my redline up to about 7800-8000, and i want to know exactly what the redline is for my motor. any help is appreciated. thanks
