K26 on 200 20v

[DK]

Hi all,

I recently purchased a used 3B engine to replace my older one. After
installing the engine again, and connecting the vacuum hoses I
realized that the previous owner swapped turbos. I believe it is a K26
since it does not have a vacuum port on the housing upfront that goes
to the wastegate frequency valve. Now, not sure what to do I got
advice from a shop and recommended that I take the housing off and
drill and tap a port in the housing.
I still have the k24 that has a bit of play. I am not sure if the
housing are interchangeable, but could work. What other options do I
have, besides swapping the entire turbo. What about quick tap turbo
lines that go into the rubber hoses? Like this one?
