Alright I searched and found a lot of different answers to this,

What's the boost preset for the Greddy TD05-18G turbo for the LS. Some say its 5.5 - 6.5 psi some say its 7.5 - 8.5 psi.

On the actual manual that comes with the turbo it says it fluctuates from 0.6kg/cm - 0.5kg/cm^2. Anyone up for the conversion? Thanks.

 

Alright, don't do the conversion, somebodys gotta have an idea what the greddy turbos run at straight out the box

 

It's about 7psi 'stock.'

 

on the 99-00 SI 18g Kit my boost held @ 5.5psi with the stock exhaust and Cat.

I think the LS and GSR are 7 psi

 

oooh wat, I doubt it's anymore for the LS kit then, that's not gonna push an LS into the 170hp range.
