Yups, your BOV and comp cover / actuator annotations are correct in the second photo. That first one though? Need better picture, but looks like some scraggly looking boost lines. Cant be sure but looks the ones to the actuators? I have had em in years. U could try blowing through it.

I have a pic here of my engine that shows the vacuum lines...

The hose in your pic #1 goes from the vacuum pipe to the pipe thats joined to the o2 sensor harness bracket and then from there (where the blue termintor cap is) another hose should go to the rear turbo wastegate actuator.

well in the first pic the blue vacuum hose is to the actulator. i found a pic anyways, looks like it goes to the return pipe of the stock BOVs i have blew in it and the air comes out of one of the vacuum hoses in my second pic, cant remember which one. i am trying to figure out what to use the the EBC

heres the pic

Ok sorry in the pic the blue hose looks like its just a blanking cap but its just the pic that makes it look like that. So anyway its going to where its supposed to go. Your right about the other hose, it is the turbocharger intake vacuum signal. It goes from the recirculation pipe y-piece and is normally connected to the top most pipe that runs behind the head. It comes out on the intake side of the engine and then is connected via a hose to the front port on the stock boost controll solinoid. So in other words just connect it to the port on your EBC that requires to be connected to the intake of the turbo.

Hope this helps :domokun:

    • The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.    
    • Bit wet, but YUMMY
    • Keeping in mind that I am currently getting flat 10 L/100km on my RB25DET, which means >>500km/tank. I would test this car for vacuum leaks, check codes and AFM signal with NissDataScan as D says, check plugs, do a compression check while they are out.
    • It is hard to be specific half way across the world...but it *seems* like it might have a minor issue. Is the idle stable and does it rev smoothly? I would not expect any pops out of what I am assuming is a standard ECU, standard tune, standard exhaust. You can use Nissan Data Scan to find out exactly what is happening when it runs, the cable/software is reasonably affordable if you are not planning on changing the ECU (which hopefully you are not with an NA skyline) BTW your mileage may not be that far off, these are heavy old tech cars, and being NA might mean you use a heavy foot to keep up with traffic....
    • Hey guys! Y'all are the masters so figured I'd check in on a few items here. - My engine sounds ever-so-slightly more raspy than the other NA RB25s I've listened to. It's barely noticeable but definitely a slightly different sound. - When I back off the throttle at high RPM, I will sometimes get a pop out of the exhaust, assuming this can be diagnosed as misfire. Some history on the car: - Had an exhaust leak in auction sheet but was claimed to be fixed by seller (bought from USA importer).  - Car's coil packs and sparks were replaced when it was sold to me, but unsure on what the gap is and whether the coil packs are correct.  - A prior mechanic had misdiagnosed a pilot or throwout bearing sound as LSPI/detonation. Had played with timing a bit, pops/raspy sound of engine just got worse. Got timing reset. - Had failed emissions a few times. First time went in as is, failed. Second time, replaced cat, still failed, running rich as hell. Third time replaced o2 sensor, passed. Car still smells gassy though. - Timing belt and valve cover gasket also replaced.  - Gas mileage is... low. about 350-400K per tank.  Any idea if I'm having any serious issues here or does this all sound like normal old NA RB stuff and I'm fine to drive it with the pops/slightly raspy engine? If it'll help, I can get drop a video of the sound of the engine.
