Oil restrictor required on aftermarket turbo?

[Ty1]

Ive done a fair bit of googling and sau browsing on this issue and cant find a definitive answer. So im in the process of fitting a kinugawa td06h-20g (journal bearing) on my r33 and not sure on whether i need an inline restrictor. Too much oil and it will blow the seals and not enough oil and it wont be sufficiently lubricated so i want to try and get it spot on. Im still running the stock rb25 oil pump with no oil pressure issues whatsoever. The oil feed port on the turbo itself has a built in restrictor (1.5mm) is this sufficient or should i fit another 1.5mm restrictor on the turbo end of the braided oil line. The hoses i purchased are genuine earls brand and the oil feed line is a 4an size hose.

You could ask kinugawa themselves. As journal bearing turbo I would guess no for additional restrictor

No restrictor needed in the line for that.
