Turbo Lines Help

I have just finished re-turboing my r33 gtst but i am unsure where all of the vacuum lines need to connect. The first photo shows the t-piece with A going to the blow-off return pipe on the intake of the turbo. B goes to the waste gate actuator and C to the boost controller (with the other controller connection going to the intake). IS this correct? and does it matter which side plugs into the  connectors of the boost controller (currently the t piece goes to the bottom of the controller)

 

Also this may or may not be related but there is another random hose left unplugged on the drivers side near the boost gauge (but isn't the boost gauge line) that disappears down into the body work. its also not the rear windscreen washer either.

 

I bought this car off an older guy a couple years back and was given the turbo pieces in a box with them assembled roughly as seen in the photos but i have learnt to not trust him after seeing his electrical work (exposed, permanently live wires simply twisted together and run across the airbag sensor) so i have little faith that it is correct.

Cheers in advance,

Joe

Been a while since I saw a stock set up but ...Boost signal comes from the nipple on the intercooler pipe just above the letter A  to a T - one line (C) goes to the bottom of the boost solenoid valve and the other (B) goes to the turbo actuator.

Originally there is a restrictor in the line but can't remember just where sorry.

The line from the top of the boost solenoid goes to the bov return pipe. Not sure why you have a red line going over to the plenum. The other lines from the plenum go to the BOV and one to the FPR

Just looked at mine , that fitting on the front of the plenum goes to the fuel pressure regulator hose .

The rear plenum one goes to the standard boost gauge solenoid box gadget .

Non standard boost solenoid here but one side goes to the waste gate actuator and the other the barb on the steel IC return pipe that feeds into the cast aluminium crossover pipe .

A .

Ok so the last picture i posted wasn't at the best angle (it looks like the random hose i'm holding is going into the FPR bung). Turns out i shouldn't trust anything on this car, the hose i was holding ran into the body work but i found the other end and it was plugged up (the guy who owned it had a habit of running extra/unneeded wires, like the 4 set of RCA leads to a single sub). Cheers for all the help guys i've finally got my head wrapped around this mess and now all i have to do is plug the hole he added to the plenum to run what i think was a boost gauge.... some people... 

 

Cheers again.

    • Welcome to Skyline ownership. Yes, it is entirely possible parts websites get things wrong. There's a whole world of inaccuracies out there when it comes to R34 stuff (and probably 33 and 32). Lots of things that are 'just bolt on, entirely interchangable' aren't. Even between S1 and S2 R34's. Yes they have a GTT item supposedly being 296mm. This is incorrect. I would call whoever you got them from and return them and let them know the GTT actually uses 310mm rotors. Depending on where you got them from your experience and success will obviously vary.
    • Hi...a bit a "development" on the brakes. I spoke to the guys where i get brakes from...and they are saying that 296mm EBC are for R34 GT-T. I then went to their site: https://www.ebcbrakes.com/vehicle/uk-row/NISSAN/Skyline (R34)/ and search for my car(R34 GT 1998 - it has GTT brakes) and it show me this USR1229 number and they are rly 296mm rotors... So now iam rly confused... The rotors i have now on the car are 310mm asi shown... So where is the problem? Does the whole EBC got it wrong or my calipers are just...idk know what?  
    • Oh What the hell, I used to get a "are you sure you want to reply, this thread is XX months old" message. Maybe a software update remove that. My bad.
    • This is a recipe for disaster* Note: Disaster is relative. The thing that often gets lost in threads like this is what is considered acceptable poke and compromise between what one person considers 'good' looks and what someone else does. The quoted specs would sit absurdly outside the guards with the spacers mentioned and need  REALLY thin tyres and a LOT of camber AND rolling the guards to fit. Some people love this. Some people consider this a ruined car. One thing is for certain though, rolling the guards is pretty much mandatory for any 'good' fitment (of either variety). It is often the difference between any fitment remotely close to the guards. "Not to mention the rears were like a mm from hitting the coilovers." I have a question though - This spec is VERY close to what I was planning to buy relative to the inboard suspension - I have an offset measuring tool on the way to confirm it. When you say "like a mm" do you mean literally 1mm? Or 2mm? Cause that's enough clearance for me in the rear :p I actually found the more limiting factor ISNT the coilover but the actual suspension arms. Did you take a look at how close those were?
