Hey guys/girls, do you know whats a good turbo for the first turbo change from stock. i don't have any turbo psi controllers. I have had my car for 5 months and i have already blew the exhaust seal. So now at high RPM it makes a sweeking sounds and it blows out oil. I have been looking into the SP turbos. But changing to a very large turbo from stock, i think would be useless. I am also thinking of other upgrades but i don't know what i need and should start to get first. I have a FCD but thats about it. and 3' pipes all-around. I know i want to get a new turbo very soon so if you can help me out that would be great thanks for your time and help guys/girls.
