Oil Ristrictor

I need to know what size oil restrictor to use on my turbo setup. It is a Garrett TE27 (T28) turbo. I have a 3an feed line and a 10an drain line. My oil pressure on cold start is 85-95psi and once warmed up it is 75-85psi. I had the crank cut, new bearings installed and new oil pump. That is why my oil pressure is higher. Thanks for the help.

I believe the magic number is .065 but that shouldn't be needed with a 3an line but you could use it still

IMO you should always be running a restrictor. .065 for journal bearing.

I would agree with this for the Journal bearing T28. I believe it uses a 1/8thNPT fitting for that cartridge. with that high of an oil pressure at cold start, .065" or .060" would be just fine.
