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.

The hose in question outlined in red

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.

    • just an update to this, poor man pays twice  Tried sanding down the pulleys but it didnt do the trick. Chucked another second hand alternator in the na car which I got for free off my mate and its fixed the squelling. Must have been unlucky with the bearings.    As for my turbo car, I managed to pick up a cwc rb alternator conversion bracket + LS alternator for 250 off marketplace, looked to be in really good nick. Installed it , started the car and its not charging the battery.... ( Im not good with auto elec stuff so im not sure if this was all I needed to do but I verified such by using a multimeter on the battery when the engine was running and I was only getting 12.2v )   I had to modify the earth strap for the new LS alternator , factory earth strap was a 10mm bolt which did not fit the bolt on the LS alternator which was double the size so I cut it off , went to repco bought some ring terminals that fit, crimped it onto the old earth strap and bolted it up to the alternator , started the car and same issue. Ran like shit and was reading 12.2 at the battery.  For a "plug and play" advertised kit thats not very plug and play but alas.  My question is , am I missing something ? Ive been reading that some people recommend upgrading the stock 80 amp alternator fuse to a 140 amp but I dont see how that would stop the alternator charging especially at idle not under load.  Regardless ive pulled it out and am going to get it bench tested by an auto elec tomorrow but it would be handy to know if ive missed something silly or have done something wrong.   
    • My wild guess is that you have popped off an intake pipe....check all of the hoses between the turbo and the throttle for splits or loose clamps.
    • Awesome, thanks for sharing!
    • To provide more specific help, more information is needed. What Android screen? What is its wiring diagram? Does the car's wiring have power at any required BAT and ACC wires, and is the loom's earth good?
    • So, now all you need to do is connect the 2 or 3x 12v feeds into the unit to permanent 12v, ACC 12V and IGN 12V that you can find in the spot behind the stereo, and the earth, and then it will switch on with the car.
