T4 oil inlet flange flawed?
I purchased this T4/T3 flange for my 62-1 setup. I inspected the product upon arrival and noticed the oil delivery hole on the contact side of the flange is EXTREMELY small. I am talking no bigger then the tip of an ink pen in diameter.
The flange threaded inlet is -4AN in size.
I just am unsure of this and have a hard time believing it will deliver much oil under hard pressure. This compared to my factory turbo oil hardline it is very very small. The factory oil hardline(S5 TII) hole diameter looks about 1/4''.
Anyone fill me in?
Thanks.

+1. Oil restrictors for the centre housing -- The FD motors run a factory oil pressure regulator of 105-110psi that'll "overload" the centre assembly and produce blow-by into the compressor and turbine. May also have a negative effect on oil drain and sump breathing, too.
Edit: Noticed you said you've got an S5. If you're using a factory motor still, then the oil pressure regulator on it is a 65-70psi unit. You don't need a restrictor for the turbo at that pressure.
