need help with feed line sizing
 

i have a turbo i plan to put on my ninja 6r in a few weeks and i want to know what size oil line i should go with and if i need an oil restrictor since oil pressure gets pretty hi... i checked out the manual and it sais" Oil Pressure
Standard: 131 ∼ 161 kPa (1.34 ∼ 1.64 kgf/cm²,
19 ∼ 23 psi) @4 000 r/min (rpm), oil
temperature 90°C (194°F)"
it's a small journal bearing turbo (tdo3)
thanks for the help ahead of time...
