i have a T3/T4 turbo, that i recently upgraded to a -4an feed line, and i havent been running a restrictor, which is my fault, cause i got to lookin at the old Ghetto feed line that was on it and it had a restrictor. I was gettin some smoke in boost and i had the motor in another car(with the same setup)and the only thing i changed was the feedline and the drain.(-10an drain line). i have only drove it for about 200 miles and i just ordered a function 7 restrictor flange. Has any one else ever had this issue? I hopin that i get the restrictor and it quits. Or do you think drivin it 4 a couple hundred miles has hurt it? thanks

 

it could have blown out the seals but more than likely it will be ok with the restrictor.

 

i sure hope so. My restrictor should be here in a day or so.
