I am currently running a garret t3/t04e 57 trim turbo the seal on the exhaust side is starting to leak so it smokes every now and then. I think i am gonna go with a precision turbo this time just wondering which one i should get. I was thinking about an sc34.

 

What turbo you want will be determined by how much power you want to support. If you don't need more than 550hp, go with the SC50.
