Cobalt Addiction Kit stage stage 4 kit...is it worth it..the power is obviously more than the gm s2 kit,and boost is 20psi..will it be safe and reliable to use on the stock heat exchanger?75hp/trq gain over stock

 

boosting 20 psi is going to need some supporting mods like a new heat exchanger imo

 

yeah a stage 4 is pushing it, especially if ur ss is a daily driver. i heard 20 psi is over blowin the sc.

 

Supporting mods would be a good idea for that much boost. Water/meth, H/E, dual pass end plate, etc are all great ways to help with the added heat.

 

so pretty much if your willing to spend the money go with the stage 5 that comes with all the essentials like the h/e, meth etc. imo its worth it

 

Yup... ( I was the test car so any questions.... just shoot em over) .... def at least go with the meth
