Kind of a long shot.

Anyone happen to know the pressure fitting/boost reference fitting size on a borg warner S257SX-E? They now come with a partially pre-drilled hole. I meant to call them today, but seems like I missed their hours. I have a full cart from summit racing and I’d like to get the parts coming if I can find out the fitting size.

Picture for your time!

Edit: I managed to find some time and go to where my car is and measure the hole size. It is 8.4mm. According to AGP who I bought it from the hole is actually already threaded for an 1/8th NPT fitting and just needs the final bit drilled to accomplish sending of the signal. I looked at the hole in low light so definitely could be the case.
