Internal Questions
Just wondering how much power can I run on stock internals without pushing them ? The XB is my daily driver and I want to turbo mine w the descendant kit w injectors and everything else. There is a guy on newscionxb that has one for sale that im probably going to buy with tax return. Also, will the 08-11 kit fit a 12 ? I have a 12 RS9. Thanks

iv heard 14psi on perfect tune is as high as you want to go on stock internals, Iv been running 10psi descendant kit for 2 years now on stock internals, everything fine, highest I would personally go is 12psi on stock internals but im already at 100k miles so i wont now. Plus when you go past 12psi youll need to upgrade fuel pump, lines, etc
