Just as Ollie says, as the k24 has no nipple for vacuum, as did my k26, then why does that have to mean you need one for the tb?? Surely you need to put a nipple for vacuum as close to the turbo as possible, as i did. I bought something similar to this (mine was alot better designed though) http://www.google.co.uk/imgres?q=vacuum+ni...1t:429,r:5,s:61 I then fitted it into the first piece of silicone joiner from the turbo to intercooler piping, car ran perfect.
