hey guys just lookin for some advice, thismornin i went to warm my car up b4 i left for work and i noticed

1... the engine started knockin a little, it went away after about 10 seconds, not sure if its just cos its really cold or whatever, but it stoped, was only brief

2... when i hoped in the car and pressed on the accelerator pedal, i noticed it was makin an electric noise, kind of like when ya tunin in a radio, or the feedback you get through your car speekers, but it was only when the accelerator was touched and then stoped once the reves dropped back down to idling revs, and it wasnt coming from the speekers, any ideas guys

yeah its really hart to xplain it, the noise is like. arghhh i cant explain it, it only come on to the revs of the car, and whilst idling its normal, but when reved it goes to the revs of the engine, its a real high freqincy pitched noise the sort you get in shity old cars comin through the speekers, i dono might just get it looked at because its to hard to explain, could be normal for all i know but it seems to only of come up today

i just noticed i can only hear it when the doors open, and when the engine bay is open i cant really hear it over the engine, sounds like more under the car,, could it be the fuel pump pumpin fuel since it only comes on once foot it put down, it may be pumping more fuel down to compensate to the presure on the pedal, hense why its making the noise when pedal put down, its got me &*^%ed

      Thinking of getting a Q50 300hp and just tuning it instead of getting the Q50 Red or 400R

      By 180 wanabe · Posted

      Also had a look at the Nissan JP website looks like the 400r has a slightly shorter ratio than than the regular V37 3.133 VS 2.937 which from a guy who has driven both 3.69 vs 4.11 ratios in the S15 is bugger all. Seems that the AUTO Z runs the same ratio as the 400R but can't find any info as to if its an open or LSD? More often than not the auto LSD is open

      R34 power steering

      By joshuaho96 · Posted

      Do not replace the power steering lines with this stuff. If it's anything like the Chase Bays stuff it will leak and be worse than stock. The reason why the reservoir is on the LH/passenger side of the car is because that's just where the reservoir was most convenient to fit. Don't overthink this stuff. The intake/cold side of the engine is pretty busy on these cars. And again, the hardpipe is designed to be a janky power steering cooler. In theory you can replace it with a real power steering cooler but that's really only for track use where boiling the fluid is a distinct possibility. Start with the low pressure lines feeding the pump from the reservoir. Make sure there isn't a bunch of junk in the reservoir filter. Be careful to not get ATF all over the engine bay. I hate dealing with ATF spills, you can clean it up and the slightest crevice will still release more oil that can still drip over time. You also want to inspect for leaks before you make a mess and can't tell what happened. Most likely you have a leak somewhere that is allowing fluid out and air in. Failing that it's allowing air in but not fluid out. Only place I can really see that happening is on the low pressure side because the pump will pull a slight vacuum to draw fluid in. Everything after the pump is high pressure or lower pressure, approaching atmospheric by the time it returns to the reservoir.

      Skid pans in/around Sydney?

      By Kinks · Posted

      I did a skidpan night at SMSP this week, it was much cheaper than $350. But yeah, you need to slap an LSD in that thing.  I put an OS Giken in the 370Z and it's f**king MARVELOUS even compared to Nissan's viscous LSD. So you're saying it's free now that it's a housing estate? 😂

      Nah, the car seems to run exactly as it did prior, in saying this it does "seem" to be better down low, like more eager to rev, but that may be 100% placebo effect from intake noise But, I'm not worried about it at all, in the end it is a fairly low compression NA engine that has a well shrouded intake,  if it is getting hotter IAT I cannot notice anything negative performance wise from the seat of my pants thrashing it about on the street or sitting in traffic, so meh, car now now makes induction noise so I'm happy

      Do you have an IAT sensor? It's worth checking it to see. You may be suprised how little gap you actually need to flood your engine with hot air. (I tape up my airbox for a reason) :p
