R34 Gtt Voltage Fluctuations

Hi all

Ever since I got my car ive noticed that the voltage fluctuates.

For example, when winding up the power windows, the voltage will go down a little, then spike down some more as the window reaches the top and kinda stops winding.

No big deal to me as I think thats probably normal.

But sometimes, when I drive, if I press the brake pedal, the voltage drops down a volt or 2 very quickly and then rises again. Sometimes little things like this happen which make me wonder if there is a need for a grounding system or something.

Does the same happen to you? is it normal? is it worth fixing with a cheap grounding kit?

Thanks all

Hi,

The power windows fluctuation is normal. As for the brake pedal, I don't get it. Maybe an issue with your battery? I get it when the xenons charge up only for a split second though.

Yeah I think the voltage fluctuation is due to the brake lights lighting up, only happens sometimes.

I had to replace my battery since it was getting old, even with a brand new battery it still drops and spikes here and there upon things like stepping on the brake pedal.

Try turning your stereo up full volume...u'll notice tht too :rant: Its normal I'm pretty sure.

I get that. Happens when I turn on my alarm as well.

Small spikes that occur as the result of an action ie; using windows, sunroof stereo etc. shouldn't be a problem.

      RB26DETT Sketchy boost mod?

      Bit difficult to follow. Have a look below and see what the standard R32 layout was like. Note there was a restrictor in place immediately before "turbocharged pressure control solenoid" that, if removed, magically got you 1 bar boost.

      I might be way off the mark here.. there must be a T junction under the manifold. That takes manifold pressure through a check valve prior to the T, one side splits out to this bleed off orifice, the other straight to the wastegate actuators.

      Carrying out some engine due diligence before my first drive in a 260RS that has been in storage for 10+ years, and found two lines that are susposed to be plumbed into the boost control solenoid. One of the lines (the wastegate boost supply line) to actuate the gates, had a bolt in one end blocking it. The other line (main boost signal line) from the very rear of the intake manifold (RB26DETT) and runs up to the boost controller had this pill in the end of it as seen in photos. Other than the obvious (T28 Ceramic turbos might well be cooked)  Can anyone shed any light on if there is any validity at all with this mod, bleeding a constant fixed rate of manifold boost pressure off through this 3mm hole?  Is it deliberate?  Was this a 90s Jap mod done to RB26's? Or has someone just fitted this without any idea of what happens to ceramic T28s if they are not gate controlled?

      This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
