hey guys

I finally got my gauges in (Boost/Vacuum and Air/Fuel). I bought a greddy rs BOV with recirculation kit. I am buying the MBC tomorrow morning. I have a cold air intake but other than that my car is all stock. How much could I turn my boost up. How many PSI my car will handle without going lean on the fuel. PLease let me know.

 

14-15

 

15 is the highest you should go in terms of safety, but i believe fuel cut will not happen til 17 or 18

 

so if I run 12-13 I will be alright with everything.what should I change to go up. also am I going to be able use everything if I upgrade my turbo.

 

no its safe to set it at 15. and no, if you upgrade your turbo you will need to upgrade your fuel system to run higher psi.

 

how many psi is the stock gst do u know?

 

i believe a stock gs-t and gsx run 6-7 if you take of the restrictor it takes it up to 8 or 9. you should be thinking about an exhaust around this time.

 

does anybody know how much boost the stock turbo runs please let me know

 

stock is more like 11-12, you can turn it to 16 with a mbc

 

11-12 stock. the turbo is limited to 17psi max.
