I am planning on upgrading turbos and I think I want to go with the Gt 357's but would like to know how good they are in comparison to other turbos like the DR's and 13g and 15g's. I want to run around 18 to 20 pounds of boost without sacrificing streetability and reliability. I will also more than likely be going with 720 injectors and all the required fuel upgrades. Please let me know what you think.
