What Oil Restrictor do I need?

[Shane@DBPerformance]

Here is what I do on my own DSMs, if your turbo blow a seal or dies from oil starvation though, don't blame me.

Mitsu Turbo with balance shafts: Head port
Mitsu Turbo without balance shafts: Head port
Garrett/PTE/Turbonetics Journal Bearing Turbo with balance shafts: Oil filter port
Garrett/PTE/Turbonetics Journal Bearing Turbo without balance shafts: Head port or oil filter port with FP journal restrictor/filter.
Garrett/PTE/Turbonetics Ball Bearing Turbo: Oil filter port with FP DBB restrictor/filter
Holset turbo: Goodluck

-3 feed line max.
Big, no crimp, no uphill oil return line with the turbo center section pointing as straight down as possible.
