boost adaptor

I want to drill and tap my intake mani and i need to then screw in some kind of adaptor that will allow me to attach a 5mm vacuum pipe down to my turbo. my question is does anyone know where i can get this adaptor?? or what it is called as i'm desprate to do this while i still have the mani off.

Thanks Sam

if you've got access to an RS catalogue it's easy, you need an SMC 1/4" BSP to 6mm push fit elbow, if you havn't I might be able to find a spare one - pm me your address and I'll see what I can do.

bugger , just reread your post, your using 5mm vac pipe, dont have a fitting to fit this, is it hard rubber hose or the braided stuff?

i'm not sure what size the turbo vac pipe is :S i just assumed that it was 5mm i managed to find a adaptor in the demon tweeks catalog and have ordered it along with some 5.6mm silicone pipe, it's to replace the vac line that comes from the turbo to the wastegate so that the wastegate gets the reading from the mani insted

on the right side of the inlet mani there is a bolt that doesnt appear to do anything, anyone know where i can get an adaptor to fit in there? would save me drilling and tapping the mani.

ok i've found out that it is a m12 1.75 thread, anyone know where i can get one in this size?

Did you do this mod in the end mate did It make a improvement ??
