BEW boost pipe groove measurement needed.

Can someone take a measurement of a BEW's boost pipe groove for me? I'm looking for the depth and width of the groove in the pipe that connects to the Turbocharger. I have a factory green O-ring (x-ring) and just need to know what the correct size of the groove (gland) for the VNT17 adapter i'm making.

Thanks in advance!

I just happen to have a spare hose to measure, its 4.5mm wide by 2.5mm deep.

Thank you!
