Blocked off hose on my intake manifold

[rahilp]

So I bought and R34 GT-T recently and at the time I didn't notice but today I found a hose on my intake manifold with a screw in it to block it off.

I was wondering what this hose goes to and why the last guy put a screw in it

Theres a blow off valve which uses one of the line to the manifold

Well the correct answer is it doesn't go anywhere. Apart from the big hose that goes to your brake booster you should have a hose to your BOV, one to your FPR, one to your boost gauge (if your car comes with a boost gauge someone might have put an aftermarket one in as well)...there might have been a line going to a boost controller as well before it was realised that was a mistake....

Without checking for myself, I'm almost certain that is the vac feed to the solenoid valve that then goes to the charcoal canister.

I have a question for the OP. Why didn't you just look at the vacuum line diagrams in the workshop manual?

I just had a look on my gtt and it eventually goes to your charcoal canister. Here’s pics from mine (hose goes underneath the crossover pipe)
