Hey Guys,

So finally after looking at my busted gauge too long I have decided to buy a new one. Boost/vacuum lines all hooked up went for a test drive all fine, now to hook up the electrical and not sure what to connect where. I already have the cable through and ready to connect to stuff.

Old gauge had the orange not connected to anything, and then the other 2 hooked up to a red and a black wire under the dash. Now I'm not sure what one is what and if previous setup was even connected correctly as it was intermittent with the led working. I would just press the led change button and the light would come sometimes on, so it wasn't connected to the night lights I'm presuming.

The new boost gauge has:

White to 12v dash lighting

Black to ground

Orange to battery

Where do i find these under my dash so I can connect it up. i don't have and electrical test equipment or wire cutting devices just pliers, scissors, knife, electrical tape and zip ties. Just putting the boost lines in made me feel like Macgyver.

cheers

I live northside and if someone wants to do it I could arrange KFC or some drinks of choice as I believe these are the going rates for SAU help.

Chermy, pulling your dash out sound like a lot of work, but I don't think you can mimic it, there seems to be speaker cable wiring everything to everything and I don't think it goes to the speakers, Chris Rogers said it looked real messy under there when he did my ignition barrel. I might take it to him if I can get time and he isn't busy. Should be a 10 min job for him as the wires are ready to go. He prob take 1 look and know what to join where. Might send him a PM.

If you don't really care about how neat it's going to be, the easiest place to connect it up would be the head unit wiring loom as it will have all 3 of those (depending on headunit, the white to 12v dash lighting would be for a dimmer when you put your lights on which your head unit may or may not have). You can just pick up a fairly decent multimeter for $20-$30 and will do the job. Your head unit will have 12v battery and ground 100% but it depends who wired it and if your head unit actually has the dimmer or not.

^smartest/easiest option for sure. If in doubt see the electric guru.

      Maybe I also should have wrote that a bit better lol. I did come 8th last in English at school during the HSC, ironically spent 2 decades reading/writing specifications and contracts in IT 😂

      Right, but that's in-cylinder, there's the interaction between that and the TWC which complicates things. Pulling out timing to reduce NOx is a strategy I saw in transitional emissions vehicles like stuff from 1974 or so. The two inlet runner system is interesting but I'm not sure it makes a huge difference as far as emissions goes, is it a tumble valve? I've seen stuff like that even in cars from the late 80s.

      Swapped rb25de neo how to get the gear indication on the dash to work

      By romel · Posted

      Hello all,   so i recently swapped out my rb20de neo with an rb25de neo( engine,transmission, wiring and the diff everything) but i just cant get the gear indication light on the dash to work when i switch to tiptronic mode. Note there is a steering wheel switch beside the shifter and i dont have that. I did notice yesterday while switching to tiptronic that the indicator on the dash started to work but it didn't afterwards. Does anyone know how this actually works? Or do i still need that steering wheel switch to be connected and on for that gear indicator to work?

      Hence why I said earlier that I don't think the turbo Neos ever would have actually qualified as an LEV. I suspect the only actual LEVs that came out of Nissan were the NA Neos. Still call them all Neos. They all stil have the Neo-ness. Just that they don't all qualify as as LEVs.

      Rb26- Enlarging Std Throttle Bodies

      By sucram · Posted

      It will give gains, but you wont hit 600 It will give gains but it wont get you to 600 imo. You will also sacrifice low down and you will be adding extra volume if you port match it, more so if you port the plenum runners depending and how its done I think the only time youre going to see about 100hp gains is if the car is making well over 1k kw I do have a spare set that I was going to test with, but i dont actually think there is anything worth getting going larger. I did a fair few S14/S15 and the standard TB is fairly small, I went to 60 and in some cases 64mm which is significant over the stock unit. You can also get some weird ratio changes. I think 20kw will be a stretch on a roller dyno. If I had it apart I might mill the shafts a little and not expect much, I think the stock size is still pretty good for a street/track car even with larger capacity. I might change diameter it if its a drag only car
