So I went on turbonetics website and couldn't figure it out. It was given to me and I want to use it on my stock gsr. Just need to know what it is lol. Here are pics Lmk what you guys think

 

That is a Turbonetics T3/T04E 50 trim turbocharger. this is capable of 420whp on the stage 3 wheel, slightly more with a larger exhaust wheel.

About how much paid would it take this turbo to make around 350whp on a stock gsr?

 

About 13-16psi of boost pressure give or take. Which is about the limit on the stock internals anyway. But you'll need more than 91 octane to do it. Look into corn water or Meth/water injection if not race gas.

 

Thanks for you time im just going to sell it and buy a bigger one. Thanks
