itb vacume servo feed

where do i get a vacume from with my direct to head itbs,there is no mention in the instructions,and no drilled holes that i can see?
cheers steve

 

anyone?

 

Are you still using the old in-head injectors (guessing it's a VW) and fuel rail?

 

you have to drill the body,no4 cyl,mate had to do this with a kit bought of Badger,Bill will prob confirm if you pm him

 

If Jenvey/Badger5 DTH bodies, then each body has a cast lug in its base to drill and tap for your pressure/vacuum fittings.. either one or all 4 ganged together.

My old Jetta used to run off cyl#4 only, and had plenty of vac for std servo, with no driving difference to it being only off one cylinder.

cheers bill,what size fitting will i have to use?(for the standard servo pipe)
regards steve

 

I pulled out a standard servo vacuum conection from a 8 or 16v manifold, drilled a hole and glued it in to my ITB's. been working fine for years.

 

i think it would be better to make an out let with a thread and tap the matching thread into the body
