a bud of mine just got a turbo but we're not quite sure what it is. it has a T etched or welded to the cold side. the numbers on it are 30491 E-50 on the cold side and .63 stage 111 and 20358-03 on the hot side. also the guy we got it from said the seals were leaking and i noticed the blade edges on the snail looking piece are slight curled like they were taking some king of beating. this turbo will either go on a b16 or a b18c1 if it is usuable. also whats a good place to send for repair.
