No, if anything you should be GAINING power all across the board.

Duuude...Step back and think about it for a second....Will u LOSE Horsepower, with a BIGGER turbo? Search the forums a bit and you will see dyno sheets and other info to help you with your decision. You will gain lag bottom end, but once the turbo hits, Weeeeeeee!

Thats what i mean man, the loss of bottom end. But i guess you cant stop that because there has to be a sacrifice of power somewhere for more. Will i need injectors, and etc...

Yes, you will need bigger injectors, a fuel pump and most importantly engine management (reflash, etc)

The problem with upgrading your turbo is that there are many supporting mods that need to go with it. You will need to upgrade your fuel injectors/pump. Probably looking at 800cc injectors and a walbro fuel pump. Also, you will need an engine managment like ecutek or utec.
