Turbo ugrade with stock turbo? where can i send it to upgrade a stock turbo?
 

Im about to get my motor rebuilt and i want to send my turbo to give it a bigger turbine. I know you can give it like another stage but i dont know what that stage is called. What's it called and where can i send it?

So i want to keep the stock turbo but get it bored out and give it a bigger turbine. The guy said that if i do that and run 750 secondary injectors then it would run good with my remapped computer without having to get another computer.

He can do all that but i think if would be cheaper if i just did it myself and then sent it to him to install it. But yeah can anyone help?

Enough said!
