Installed a dual stage boost controller (turbosmart)c On my RB20 Now the car sounds like it's not runnng on all cyclinders, or has a bad boost leak.. then stalls. This is just at ide, the way i have it set up is. the hose flowing from intercooler nipple to wastegate (obviously with the bleede valve in the middle. arrow pointing towards the wategate. I plugged up the nipple on the comp housing with a screw.. anyway. so i hooked it back up to the comp housing ranther than the intercooler pipe and still the same..

--IT WAS THE INTAKE PIPE THAT CONNECTS TO COMPRESSOR, HAD CAME OFF A BIT--

thanks for the help, kept me looking.

Hmm, i returned it to facrtory and still the same. Somtimes, i wish it could just be simple.. and work. It worked on my 33 fine. Still die's at idle, and runs rough as. I took the plug to the AFM off when i put the boost controller on so i thought t could be that, but it's on there good...

So nobody has any idea? it's back to stock, checked all the hoses and wires.. all fine, the only thing i can think of. I drilled and tapped a hole in the crossover pipe, maybe a bit of shit got into the motor. (alloy shavings) but could this effect anything? It's running rough, hardley idles and smells like its running rich.

Are you certain that none of the cooler pipes have blown off?

LOL, f*kn weird isnt it? im a verry DIY person but this has got me stuffed.. i took it for a trash 1hr before i hooked up the boost controller and it ran fine, then put it on.. ran like shit.. chucked it back to standerd.. still shit! changed the AFM.. still shit... i dnt know! all intercooler pipes are fine. on another note, i'm pretty sure the 20 doesnt have a boost soinoid like the 25, cause the hose runs straight from the vacume nipple on the comp housing to the wastegate actuator.

i dont like the sound of this

was the pipe off the motor when you drillied into it?

I'd be checking the plugs and checking to see if maybe one of the tips has been damaged by some alloy debris.

that would be the first thing i'd do. if some alloy has worked ints way into the cyclinder i'd look for that before you try to fire it up again. that corss over pipe has a thick sidewall so there would be a few shavings flaoting around.

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

      By AdiR34 · Posted

      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.

      Looking for a part number for this part here

      By Duncan · Posted

      So....to find any R chassis part number, get your VIN (will be something like ER33-xxxxxx for you) and go to: https://www.amayama.com/en/genuine-catalogs/nissan and enter it. From there you have access to a web version of Nissan's part system, FAST. It is a bit tricky to get used to, so maybe have a shot and post up what you think.  You can also search by general model but note in some cases your car might have different options so VIN is safest.  On diagram 211 I got 14075-75T16 for Connector, Water Hose If I search for part 14053‑21U10 that you posted, that is also a water hose but not the one bolted to the plenum and 14075‑04U00 is the fitting where the water hose goes into the block.

      Duncan's V37.......race car?

      By Duncan · Posted

      Yeah now we are talking I much prefer coolers in the front middle because it lessens the chance of a small bump to a corner stopping the whole event. I was thinking the AT cooler can move out of the radiator, delete the AT/engine coolant interwarmer and mount a separate cooler with a thermoswitch somewhere further back as is common in racing, that would be one thing. Beyond that, the engine oil cooler is an obvious one to move to the wheel arch, potentially one on each side, but unused space is an issue. I did have a earlier pic with the bumper off but it doesn't show how busy the corners are: DS is full of the auto driving sensors and PS is totally fully of windscreen washer fluid reservoir But ultimately I was hoping to keep the AC, and the water/air heat exchanger is fundamental so it is not just the radiator that needs to be in front BTW here's airflow to the rad as it ran at the track (one horn is gone now and I'll remove the lights next time):
