Chances are that it is an amp. Skylines rarely have problems with this, also some amps will only whine on high frequencys 1st stop should be Jaycar if it's a new amp and try another. if they wont help then make them. make sure that your Rca leads are good quality and dont run too closely to electronics such as the ECU.

OK thats a start - I run OK RCA's but nothing flash. The amp is a Jaycar Response 4ch (New). The leads run from HU left and along the passenger side of the car into the boot where the amp is on a nice shelf next to the battery which I spent ages making. The AMP is earthed to the same -'ve terminal as the battery ie that piece of metal with two nuts attaching it to the chassis. The +'ve lead rund from the battery no longer than 1ft to the amp. All power cables are as thick as my little finger (about 1cm ish).

Suggestions?

Undo your kick and scuff panels and pull the rca's away from the computer and the main wiring harness and have a listen, if it's still the same go see jay car and ask them if you can try another amp.

      R34 GTR Seats / No longer reclining

      By bilbo117 · Posted

      Hi all, Long time since I've posted here. Looking for some advice on what I can remove to further identify the cause of my issues.  I can move the passenger seat forward and back but the knob used to adjust the seat angle is pretty much free spinning, there's very little resistance.  Removing the side cover I can see that the chain is intact but the shaft for the adjustment spins without the gear attached to it moving.  What's my next step for disassembly here? Is this a common fault? Just being a little cautious as I didn't want to start removing bolts for a spring to fly out or something equally as stupid.  Cheers

      Those above shitboxes, mediocre and above usually have a turbo strapped to them, hence the slightly higher octane is required.

      I mean, I got two VASS engineers to refuse to cert my own coilovers stating those very laws. Appendix B makes it pretty clear what it considers 'Variable Suspension' to be. In my lived experience they can't certify something that isn't actually in the list as something that requires certification. In the VASS engineering checklist they have to complete (LS3/NCOP11) and sign on there is nothing there. All the references inside NCOP11 state that if it's variable by the driver that height needs to maintain 100mm while the car is in motion. It states the car is lowered lowering blocks and other types of things are acceptable. Dialling out a shock is about as 'user adjustable' as changing any other suspension component lol. I wanted to have it signed off to dissuade HWP and RWC testers to state the suspension is legal to avoid having this discussion with them. The real problem is that Police and RWC/Pink/Blue slip people will say it needs engineering, and the engineers will state it doesn't need engineering. It is hugely irritating when aforementioned people get all "i know the rules mate feck off" when they don't, and the actual engineers are pleasant as all hell and do know the rules. Cars failing RWC for things that aren't listed in the RWC requirements is another thing here entirely!

      Best place to order Authetic R32 Parts in Japan

      By GTSBoy · Posted

      I don't. I mean, mine's not a GTR, but it is a 32 with a lot of GTR stuff on it. But regardless, I typically buy from local suppliers. Getting stuff from Japan is seldom worth the pain. Buying from RHDJapan usually ends up in the final total of your basket being about double what you thought it would be, after all the bullshit fees and such are added on.
