Default Can anyone tell me the size of these fittings from the Begi kit?

I'm thinking I will go ahead and upgrade the rubber lines that came in the Begi kit with either hardlines or stainless braided...I want to use as many of the fittings that came with the Begi kit that I already have, but I'm not sure what sizes they are. I've attached some pics below-I just need to know the size of the side that would go to line (so I don't need to know the size inserted into either the block or turbo itself). Thanks!

Also, I'm thinking of doing hardline for all the lines (bending and flaring myself)-probably aluminum/maybe stainless but I'm correct that the proper OD tubing can be used with a sleeve and nut to fit to these? I'm thinking these are -AN fittings/37 degree flare, correct? I appreciate any help!

I want to do something similar to what this guy did:

Also, anyone know if the Garrett GT2560R turbo that comes in the Begi kit has a built in oil restrictor?

you don't need to make provisions for a restrictor on BB turbos.

Oil feed is 7/16-24 Inverted Flare on the turbo
coolant ports on the turbo are M14x1.5

oil feed port on the block is M10x1.5
coolant feed port on the block is M12x1.25

Ball-bearing turbochargers can benefit from the addition of an oil restrictor, as most

engines deliver more pressure than a ball bearing turbo requires. The benefit is seen in

improved boost response due to less windage of oil in the bearing. In addition, lower oil

flow further reduces the risk of oil leakage compared to journal-bearing turbochargers. Oil

pressure entering a ball-bearing turbocharger needs to be between 40 psi and 45 psi at the

maximum engine operating speed. For many common passenger vehicle engines, this generally

translates into a restrictor with a minimum of 0.040" diameter orifice upstream of the oil

inlet on the turbocharger center section. Again, it is imperative that the restrictor be

sized according to the oil pressure characteristics of the engine to which the turbo is

attached. Always verify that the appropriate oil pressure is reaching the turbo.

The use of an oil restrictor can (but not always) help ensure that you have the proper oil

flow/pressure entering the turbocharger, as well as extract the maximum performance.
So Garret says BB may benefit is pressure is above 45psi/3bar. Which I think qualifies for a restrictor in a Miata. Question is, do BEGI components incorporate a restrictor or what should we do?

No we do not incorporate a restrictor. Usually, it is not needed.
