Hello,
I am currently running the Forge DV's on my N54. I am looking to upgrade the vacuum lines off them. I am currently just using the stock lines which i believe are 3.5mm.

I was thinking of getting the Bov adapter from Burger Motorsports. However the fitting says its 1/4?
Is anyone else using the Forge Dv and have upgraded there vacuum lines? I was thinking even a 4 or 5 mm would be fine..however i am unsure if that will be too large for the forge nipples and too small for the BMS adapter nipple.

Any help in this area would be great. Thanks

aren't the stock size lines fine for the DV setup?

I run the turbosmart ones with OEM sized lines

I think yes they are fine, I dont have issues like running a tail with stock lines. However, i did stumble across a thread where some DV users found slightly upgrading the lines made their Dvs more responsive.

My lines are old and gross. I just ordered some 4mm lines(only slightly bigger) and they should fit fine. Going to keep it on the stock nipple too.

thanks
