what does this gauge tell you anyways?? new to this still trying to understand my car

On your turbo dump pipe (which leads to your exhaust) you have a sensor which detects 02. Based on this info the ECU will lean out the fuel whenever it is safe to do so (when you back off the throttlle etc etc). If the sensor isnt working properly then the ECU wont lean out the fuel when its possible so you will get crap fuel economy :) for one thing (200k's to a tank). This gauge can tell you if the sensor is working or not.

on the stock sensor all the gauge does is tell you if the sensor is working or not. i have 1, simply for the flashy lights. that is the whole reason i bought it. i'm like a lyre bird. attracted to flashy things. i bought it a few cars before my skyline.

as for the wire, its easiest to go off the wire straight off the sensor off the dump. i did it on the sensor side of the plug (so its a bit away from the heat. also solder the wire on (and use as little as possible), don't use joiners as there is a voltage drop across them and will give your ecu false readings. remember the sensor works in 0.1v ranges so having a voltage drop will change what the ecu reads.

Got one of these for my bday, and now trying to hook it up. I fed the signal wire to the engine bay, just want to know which of the 3 wires on the o2 senser do i connect it to? i see a white/blue, copper, and brown with tracer? this is on a RB25DET.

Cheers...

Do a search on "oxygen sensor" or "o2 sensor" It should come up with some links on wiring ford el sensors with the nissan wiring. And the colours.

One of them is the signal wire the other two are the heater wires.

      Potential MAP Reference Point

      By joshuaho96 · Posted

      Isn't there a fitting on the back of the balance tube? That's what the OEM boost gauge uses.

      Potential MAP Reference Point

      By GTSBoy · Posted

      Getting a decent signal from all 6 throats is a challenge. I don't know for sure, but I suspect that the stock balance tube is not ideal for it. I have done it on an ALFA 4 cylinder (about 35 years ago, so don't ask for too many details). We drilled 4x holes in the manifold runners, put in some fittings and ran hoses to a decent sized (I think it was about 20mm diameter) pipe that ran the length of the inlet manifold. So, it was quite a decent volume. There is a "tuning" balance to be found between the volume of the common plenum on such a thing and the diameter of the pipes running from it to the runners. You need the volume to be large enough to damp out the sharp spikes in pressure signal you get as each runner gets sucked on by its cylinder, but not so large that it becomes too slow to respond to actual changes in MAP. And you need the hoses to be small enough to transmit the signal quickly, but not so small that they delay the signal. You might have to have more than one go at it, if there isn't any actual success based wisdom to be had here. Hopefully there is. Anyway, I would not do it on only a couple of cylinders. I would also not care about "permanently modifying a part". Just bloody drill holes and make stuff better. There is nothing sacred about any GTR unless it is a genuine museum piece that you shouldn't be modifying at all anyway.

      R34 GTT front hood lip

      By Kinkstaah · Posted

      The strange thing is this is a URAS front bumper (or clone of it). The bumper actually does not sit flush with the GTT hood - You need the addon to make the hood 'long' enough to reach the bumper. I have no idea why they didn't incorporate this piece into the bumper itself.. instead of sticking it to the hood instead.

      R34 GTT front hood lip

      By AdiR34 · Posted

      Another thought on this OLD topic: When you paint your bonnet lip, leave a small unpainted back lip/line along the back of the lip, where it rests on the bumper. That way, the line in the back is much more prominent than the gaps in the front/under the lip - and it breaks the hood-to-bumper connection at the "correct" place, when comparing to a GTR. I'm gonna do this with mine this week, so stay tuned for pics!
