Hey all kind of an annoying problem.

I have a GCG highflow 33 turbo on an RB20 with stock ecu.

I have GFB atomic bleed valve.

Problem just wanted to check the boost before I put new Power FC and injectors in.

I want to run 16psi when tuning in couple of weeks.

Car is running 12psi currently but when i went to wind out the bleed valve today nothing.

No further increase be it from 1 turn or 10 turns.

Is this something to do with stock comp, turbo, or should I just get an elec. boost controller.

Main question is do people think turbo isnt able to produce more than 12psi?

Thanks any info would be great.

Hey it is connected the right way ive had it on there for over a year now.

No i do not have a restrictor just the bleed valve between actuator and comp cover. Im sure the GFB bleed valve has a restrictor in it?

The stock ECU might have a fuel/ignition cut when boost goes above 12psi.

You can always disconnect and block your wastegate line to rule out boost controller issues, but as you're no doubt aware this CAN destroy your turbo and/or engine if you don't keep an eye on the boost guage.

      The powder coating came in at $250 EACH. The TRX rims got a coat of clearcoat on the outside only.

      Pops when backing off throttle, rough-ish sound through rev range.

      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.
