Wanting to know, if I should keep the stock 33 Gtr turbos or upgrade to 34gtr turbos, what's the output for both stock turbos, I've been told the 33 turbos are good for 17-18 psi around 380-400hp although I wouldn't run that much all time, sweet spot so called. And I also heard 34 Gtr turbos power output around 480-500 with supporting mods of course. I have light mods probs to support 350-400, although will want more eventually down the track of course haha.
