Help - R34 Gtt Name This Hose

[Ben-88]

I have just picked up a R34 GTT sedan with manual conversion done. I have noticed an extra vac hose coming off the engine thats not connected to anything. I have done some searching for photos of the engine to see where it goes but none of them showed it very well with most photos being taken from the front.

I searched the engine bay for where it could go with the length of hose that is there and theres nothing that was obvious. The hose itself has a small black plastic tube broke off inside the end so its possible where ever it was connected it as been snapped off but again im unsure. I have also had a look at the work shop manual for the vac diagrams but didnt have much luck working it out.

Can anyone tell me what this hose is for and where it should be connected at the other end.

Should go to the factory MAP sensor.

I think I found it... It was a little black sensor that was no longer connected to anything. Looks like this is where it has snapped off from at least. I have plugged it for the moment as I saw in a post somewhere that it can be disconnected to remove the factory boost limit.

It look like I would have to buy a new sensor of I want to reconnect it. Is it worth the hassle if finding a replacement? Or is it fine to just keep going with this disconnected and plugged.
