New Turbo

[DriFt3r]

I just got a new T3 turbo today, after looking at the turbo I found out that the turbine side is .48 and the exhaust side is .48 or .49, it was kinda rusty. What do you guys think this turbo is? a straight up T3?

Do you any of you guys know the stock A/R's for the T25 and T28's, how do they compare?

The A/R's are not the size of the turbo. The only way to be sure of what you have is to measure the major and minor diameters of each wheel. Every turbo size can come with different A/R's so it tends not to be the best way to figure on the size. And you also can't compare the A/R's for different turbo sizes. It's apples and oranges. A/R's are nothing mor ethan the size of the nozzle in the housings. A/R's can be changed simply by replacing the housing with one that has a different A/R. But the wheels, which dictate the actual turbo size and trim remain the same.
