I have been searching and I see that people say that -4 feed line will blow turbo seals because of pressure and -3 is perfect. In reality wouldn't a smaller line cause more pressure then the bigger line? Im not sure. I already bought a -4 trying to find out if I should switch to -3.

 

Its the volume that actually floods the gravity drain back into your pan. Not the pressure. Switch to a AN-3

So your saying a -4 line floods the return causing oil to sit in the turbo waiting to be returned basically.

 

i had a -4an on m 240sx ka turbo, all my car did was smoke due to oil leaking in the turbo
