Broken vacuum pipe connector?

Hi guys. I think we've found the cause of our problems with over-idling. Please could you have another look at my thread here, which i've updated with photos. Need some help identifying the part and advice on how to resolve.

Thank you.

Not yet, want to see if a change to the end pipe shifts peak power first. TDI is great but they’re not cheap.
It is insanely loud even with the baffles, it will be close to the limit at a 105db track day, but my god does it sound good. I have a dyno session scheduled today, will post the results and the noise later.
Two reasons- the JWT cams had some marking on the bearing surfaces after the last fail, and they didn’t match the claimed specifications for duration. Could have polished them up for reuse but the Tomei looked more promising.

Hi all,
Ive posted something along the same lines ages ago but I am completely stuck.

1990 300zx na
I have rusty rear sills that need to be fixed along with some minor rust underbody. I have sourced stamped replacement parts for the rear sills.
I need my ebrake replaced including the cables.
Have the full replacement kit from concepts
But for the life of me, I cannot find any place that will touch it with a 10 foot pole.
I even have the centre console out to make life easier but every place might as well hang up on me when I tell the vehicle.

Based in Wicklow. I'm not looking for an immediate 2 day fix, if it needs to be a side project for a shop for a few weeks that's better than it looking sad in my driveway.
Anyone know anyone who might work on it? I need this done to pass the NCT. After which, all other regular maintenance things I would do my self that doesn't involve being under the car.
I never imagined it would have been so hard to find a place.
It's in good shape otherwise. This is purely to pass the NCT.
Thanks in advance to anyone who can help a fellow Z owner out!

Also what was the reason behind switching to Tomei cams from the JWT? Weren't the JWT's more aggressive? Or did you go to a non-solid lifter cam profile?

Are you going to pass noise testing with that system? Looks like there’s not much silencer at all.

Looking good! Are they still drawing up a custom set of headers?
