So i searched and found a member here was recommended to use 4an for his s400 and I was unsure if the s300 uses the same? I googled it and found on a supra forum a quote from bw saying to only use 3an line. So whats everyone using on there s300 setup? I plan on using a 10an return. Thank you

 

Would think -4an feed with at minimum -10an drain would do the job..

 

I actually just switched to -3 from a -4 on my S366. Have not had a single puff of smoke during start up or acceleration since.

 

Neutron, did you make your own? If so can you point me in the right direction please

 

This was the only line on my car I did not custom make. Ill post a parts list latter on tonight.

 

Thanks man.

 

fullrace says to use a 3an.

"Application Notes:

3AN oil feed line is recommended. If -4AN or larger is used, an oil restrictor is required (just like GT turbos)."

 

gonna go with this hose

seems to be perfect

 

Here is the line I used. Earl's pre-built line and is the perfect length of my turbo placement.
