I was told that after time the turbo would perform better. Personaly don't believe there is a break in period for my GT30R.

 

I don't think it would be a great idea to slap it on and go do a 3rd gear pull up to 100 but I don't think your going to hurt anything. What is there to break in? Its a shaft that spins crazy fast.

I say false. and I want your turbo.

 

I don't believe it was a break in thing at all just the fact that I found a leak in the piping and it ran a lot better. first dyno was 321hp now I would guess 350 to 375hp. Redyno next month and we will see.
