Best place to mount a gauge?

Hey guys,

Just got myself a new boost gauge and i'm trying to work out the best place to mount it. I've done a few searches and found what appears the be the best vac line to tap (the one that runs from the back of the plenum then runs left to the back left hand side to a little black box, which i am told is the stock boost sensor). My only conundrum now is trying to work out where to put the gauge.

I've spent alot of time sitting in the drivers seat and placing the gauge holder in different places, but i cant seem to find a place that combines easy access to wiring and a short route through the fire wall with a useful legal line of sight mount.

I'm been pondering trying to mount it at the base of the drivers side a pillar, its below wheel level and still sits within my view when i look straight forward, but when i look at the available holes through the firewall it makes it look like i'll need to pull the whole dash.

I've also found the DIY posted on here, which is good but is now sans picks so i'm pretty much guessing that i'm looking at the right thing.

Can anyone give me a few pointers or anything to think on / consider?

Cheers

M

Get an apillar gauge holder and put it on there.

Its an Apexi EL mech gauge so it comes with a mount. My prob isnt mounting it really, its more a case of getting the tubing and wiring the the gauge. I'm not sure how to get to the hose once i've pushed it through the firewall, which hole to push it through (although i think i've spotted a good one) and how to get it from there to the a pillar.

Maybe i just need to have a good long play, but i'm hoping to avoid pulling apart more than i have to.

I got exactly the same thing, but get yourself a greedy single apillar gauge holder.

Pass the rubber tube through the firewall just under where the abs sits and a whole bunch of other wires are going through. Then get a piece of wire and pass it through to the drivers side and to the holder.

do be careful if you are mounting it on the A pillar. Alot of people mount their guages there, but I find that when you are punting hard at night, the guage sort of gives you a slight blind spot if it is mounted wrong - makes life a bit difficult for tight right hand corners.

Not sure about sydney, but in SA it is also illegal to mount guages on the A pillar. I have been told this is because it 'may' increase the chance of head injury in a collision (right, like you are going to be more concerned about the pillar guage than your head hitting the a pillar or windscreen a poofteenth of a second later????).

the best place I have seen is inside the instrument cluster. You can use double sided tape to secure it infront of the stock boost guage, and run the wires behind the steering column - under the instrument cluster, so no holes needed anywhere.

The other thing to consider is that when you are boosting, it is unlikely that you will be watching the boost guage anyway - at least I dont, things happen too quickly at full boost to be paying too much attention to anything but the road:)

Maybe for you Steve :( There is time in 3rd gear though... definitely not in first.

finding the correct vac line made me realise that i dont know where/ what most of the engine parts are... does anyone know of a good place or pic that will help me learn about a 33gtst engine bay and component locations??

Personally, I think it looks great mounted above the central air conditioner vents -- if the mount is like the GReddy ones, it'll require a little bending to give you LOS to the gauge.

I think A-Pillar mounted gauges are illegal in all states (it's a safety-related ADR), so it's probably best not to put them there.

It aint illegal if its not in your line of sight. If u have air bags u r gonna hit the airbag before u get anywhere near the a pillar anyway

i know for a fact in wa its not illegal to have pillar mounts, mine went over the pits

no probs, they also gave me a permit so i wouldnt be haseld. It does have to be set back behind s-wheel distance(reason of hitting head). I also think they mite have a prob with crome cups, but black is fine if mounted in correct position.

      Baron's R34 GT-R build thread - car in Japan for 5 years -_-

      By BaronOBeefdip · Posted

      Back again. I returned to Japan in Jul/Aug to spend time with the car on my birthday and remind myself what all the sacrifice and compromise is for. It happened to line up with the monthly morning meet in Okutama, which I have been wanting to go to for a long time. It's a unique event at a unique spot with really rare, interesting, and quirky cars. It's where all the oldheads and OGs gather. The nighttime scene at DKF certainly has its place and should be experienced if you're into cars, but there's too much bad attention and negativity around it now. IMO the better time is Sunday morning at DKF or Okutama; it's more chill and relaxed. I'm glad I was finally able to go, but not sure it's worth the drive from all the way from Nagoya immediately the day before, unless I was already staying in Tokyo for the days right before the meet, because you have to wake up quite early to make it in time. Funnily enough though I didn't drive the car all that much this trip because it was just too damn hot. While there were zero issues and running temps were nominal and the A/C was strong, RBs already run crazy hot as it is. Sure, it took it all like a champ but something about driving these cars in the ridiculous heat/humidity bothers me and makes me feel like I'm asking too much of it. I'm just me being weird and treating the car like a living thing with feelings; I'm mechanically sympathetic to a fault. Instead I was mainly driving something else around - a KX4(silver) 2001 X-Trail GT, that I acquired in May. There's a few different flavors to choose from with Xs, but visually it's the Nissan version of the Honda CR-V. Mechanically it's a whole different story as this, being the top-trim GT, has an SR20VET mated to a four-speed auto and full-time AWD! It was a very affordable buy in exceptional condition inside and out, with very low mileage...only 48k kms. Most likely it was owned by an older person who kept it garaged and well-maintained, so I'm really happy with how it all worked out. It literally needs zero attention at the moment, albeit except for some minor visual touch-ups. I wanted something quirky, interesting, and practical and for sure it handily delivers on all three of those aspects. I was immediately able to utilize the cargo and passenger capacity to its full extent. It's a lot of fun to drive and is quite punchy through 1st and 2nd. It's very unassuming -in the twisty bits it's a lot more composed than one would think at a glance- and it'll be even better once I get better tires on it(yes, it's an SUV but still a little boat-y for my liking). So...now I have two golden-era Nissans in silver. One sports car and one that does everything else; the perfect two-car solution I think👍 The rest of the trip...I was able to turn my stressed brain off and enjoy it, although I didn't quite get to do as much as I thought. I did some interesting things, met some interesting people, and happened into some interesting situations however, that's all for another post though only if people really want to know. Project-wise, I went back to Mine's again to discuss more plans and am hoping to wrap that up real soon; keep watching this space if that interests you. Additionally, while working in the tormenting sweatbox that is the warehouse, I was able to organize most of the myriad of parts that my friend is storing for me along with the cars, and the 34 has a nice little spot carved out for it: And since it can get so stupid hot in there, that made it all the more easy -after I was standing there looking at the car and said 'f**k it'- to finally remove all the damn gauges that have mostly been an eyesore all this time. Huzzah. The heat basically makes the adhesive backing on the gauge mounts more pliable to work with, so it was far less stressful getting this done. I didn't fully clean it up or chase the wiring though; that will happen once I have the car in closer possession. Another major reason to remove all that stuff is to give people less reasons to get in my car and steal s**t while it's being exported/imported when/if the time comes, which leads us to my next point... ...and that is even though it's time in Japan is technically almost up since it's a November car and the X would be coming in March, I'm still not entirely sure where my life and career is headed; I don't really know what the future looks like and where I'm going to end up. I feel there's a great deal of uncertainty with me and as a result of that, it feels like I'm at a crossroads moreso now than any point in my life thus far and there are some choices I need to make. Yes, I've had some years to consider things and prepare myself, however too much has happened in that time to maintain confidence and everything feels so up in the air; tenuous one might say. Simply put, there's just too much nonsense going on right now from multiple vectors. Admittedly, I'm struggling to stay in the game and keep my eyes on the prize. So much so in fact, that very recently I came the closest I ever have before to calling it quits outright; selling everything and moving on and not looking back. The astute among you will pick up on key subtext within this paragraph. In the meantime I've still managed to slowly acquire some final bits for the car, but it feels nice knowing there's not much left to get and I'm almost across that finish line; I have almost everything I'll ever want for my interpretation and expression on what it is I think an R34 should be. 'til later.

      Thanks for that, hadn’t used my brain enough to think about that.

      Also playing with fire if they start to flow more air down low than what the stock twins can. It's not even up top you need to worry, it can be at 3000rpm and part throttle and it's getting way more flow than it should.

      You still want a proper tune on the stock ECU though. Stock tune + stock ECU with GT-SS/-9s is probably playing with fire if you're running more than stock airflow/power.
