I need help with the T25/T28 Turbo Oil Lines

[Maichael]

And here it is the top side T25/T28 Turbine photo with the Oil Inlet line adapter with the restrictor.




Note;The oil restrictor location is in the oil adapter bolt and it is 1.5mm.I just need to know if this is the correct restrictor size and Many Thanks Again.

And i have another question:Can i use the original style K&N air filter for the T25/T28 Turbo System?

It is because i read the K&N air filter specs and this type of air filter gives a lot of air flow.

I have the JDM Racing Style Air Filter with the Flow Meter adapter but if i can use the regular style K&N filter it is better for me and Many Thanks and im sorry for this bunch of questions.
