Hey guys,

I have a 94 gts-4 skyline. Its recently imported and had a cr@p stereo in it. So i began to replace componants. I used the head unit install guide, top stuff. That went smoothly, then i discovered at an earlier date i had blown upo all 4 ic's in my head unit ( the built in amp) so i hooked up an amp i had to run the speakers. I got decent cabling- triplke insulated stinger rca's and triple insulated shnider (or how ever u spell it) amp wiring kit. I did this cause i had heard that engine noise on r33's can be a problem in aftermarket stereo's. Im looking for some advice about what could fix the problem. Should i run the rcas down another side of the car? Any advice would be helpful,

Thanks in advance

Pete

power cables should not be run Parallel with rca's clean all earths that come from deck and to the amp, check that your bat is clean and free from crap, change your sappressor on the altornator. See how that goes, also i have found if you have your gain turned up to far on the amp it will cause unwantied shit noise

you should get no engine noise whatsoever on an R33 if your cabling is wired correctly, even with relatively cheap face unit.

Just try moving your wiring around. Otherwise quite likely to be the amp. Is it sitting near the fuel pump in your boot??

Where abouts is the fuel pump in the boot - on the right?

My engine noise is driving me crazy. I have RCAs run down the left side of the car, noise supressor on RCAs, noise supressor on amp but still heaps of noise.

Would getting shielded RCA cables and running them down the middle help?

the amp is decent- i think. Its an older pioneer one- not sure on the model code, but hasnt been a problem when i have run it previously in my old vl. The amp is screwed into the sub box on top, and it just sitting in the boot. If the fuel pump is the thing on the right hand side of the boot, under the plastic cover- no it isnt, the sub is on the left hand side, the gap is slightly larger so the sub box can be pushed back further, using less space. The earth on the head unit is located im the transmission tunnel, right ner the shifter. Could that be the problem? it isnt as noticable when i only run the sub and no speakers. The noise also increase pitch (like how high the noise is) as my revs gain.

any help is appreciated

thanks

Pete

      remote oil cooler hose size, 8,10 or an12?

      -10 is plenty for running to an oil cooler. When you look at oil feeds, like power steering feeds, they're much smaller, and then just a larger hose size to move volume in less pressure. No need for -12. Even on the race cars, like Duncans, and endurance cars, most of them are all running -10 and everything works perfectly fine, temps are under control, and there's no restrictions.

      Unknown sound similar to BOV on positive boost with partial throttle RB26

      By nouveau_poor · Posted

      Update: O2 sensor in my downpipe turned out to be faulty when I plugged in to the Haltech software. Was getting a "open circuit" warning. Tons of carbon buildup on it, probably from when I was running rich for a while before getting it corrected. Replaced with new unit and test drove again. The shuffle still happens, albeit far less now. I am not able to replicate it as reliably and it no longer happens at the same RPM levels as before. The only time I was able to hear it was in 5th going uphill and another time in 5th where there was no noticeable incline but applying more throttle first sped it up and then cleared it. Then once in 4th when I slightly lifted the throttle going over a bump but cleared right after. My understanding is that with the O2 sensor out, the ECU relies entirely on the MAP tune and isn't able to make its small adjustments based on the sensors reading. All in all, a big improvement, though not the silver bullet. Will try validating the actuators are set up correctly, and potentially setting up shop time to tune the boost controller on closed loop rather than the open loop it is set to now. Think if it's set up on closed loop to take the O2 reading, that should deal with these last bits. Will try to update again as I go.

      More so GReddy oil relocation kits, sandwich plates, etc. all use 10AN fittings. And same, I've only used 10AN and my car sees track work (circuit, doing laps, not 10 sec squirt business).

      Dunno. I run -10 on the race car.

      street use or race track, what hose size and why? what factors change with the hose size options ?   see most comon is an10. when you see most oem external coolers are closer to an12? does high volume oil pump like nitto need an12 or 10 be just fine
