hi guys im trying to research up on turbos and ive got a little bit of a grasp on turbos like i know that the A.R has to do with size and how long your turbo lag is, correct? also the t3, t3/t4, t4 are all in a way the size of the turbo but more so the flange type? (bolt on pattern?) if some one could just give me a link that will explain what exactly the T3/T4 means and what exactly the a.r ratio and compression ratio mean. i have looked and am having trouble finding what i am looking for, can someone give me a link to check out or if you have time shoot me and answer. thanks for all your help, it is very appreciated.
