Hey all,

Just a couple of questions about gauges for my R34, i want to put 3 gauges in, just as an experiment and to make it look sportier lol.

I definitely want air to fuel ratio, anyone know how to wire it up?

I would also really like to monitor the air intake temperature going to my pod from the CAI, but i wasnt sure if air intake gauges are for turbo cars and it measures the intake from the intercooler? Or can i do it with my N/A, and if so, how do i wire it and all that?

Lastly, does anyone have any ideas about what other gauge i could get, most ive seen are for turbos so arent really relevant to me lol.

Im really just doing this as a personal interest sort of thing, i like the look of gauges and i would like to monitor certain things about the performance of my car, not really for tuning purposes for now, rather just as an experiment and to learn more about the car.

Cheers for any help

A/F gauge is going to be more of a filler gauge than anything else

Oil Temp, Water Temp, Oil Pressure are the first 3 gauges you should get. Obviously boost gauge is for a turbo.

You can get a vacuum pressure gauge, but once again you're better off saving money that you would spend on A/F and vacuum gauges and getting decent oil/water/pressure gauges.

Your ECU from factory is going to handle your A/F Ratios well, if anything it will have a tendancy to run richer rather than lean.

If you have a demanding sound system that requires a good stable voltage, then a voltmeter would be handle to ensure it doesn't dip too low and damage any sound equipment under load.

Save your money though, just get the oil temp / water temp / oil pressure and use the rest of the money for other mods.

The voltmeter and oil temp / water temp gauges sound like a good idea, do you know how to wire them? Ive already got oil pressure, it came stock in the dash with my car, sits under the speedo

I've heard that the stock oil pressure isn't the most accurate. I'm yet to fit my gauges (going to do it with my next service) and I'll be having oil press/water temp/ oil temp fitted.

You need the adapters to suit. Check out Just Jap.

The gauges will come with a sender unit, so basically it's a matter of wiring up the power (12v+ and ground), and the wires from the sender units.

You'll have water hose adapter which the temp senser goes on.

Then you've got sandwhich plate adapters for oil pressure and oil temp which the sender things will also attach to.

i have volts, oil temp and vac in my 34

Nicely done with the gauges at the bottom. I've seen cigarette lighters cut out to accomodate a single 52mm boost gauge before. I want to try keep from mounting gauges on the dash, though it makes it easier to see while driving. I like the paint you used on the dash plastics.

I fitted some Swoosh ones a couple of years back, they were great, I just felt 'gauged-out' with all of them in the middle though....at night it was like a commercial jet.

I had AF ratio, Exhaust temp and a Boost gauge in there.

Haha see this is what i wanna do, i like the jet cockpit look =P But yeh, i wanna have mine mounted on either the dash like this, or on the pillar, but apparently the pillar is illegal now, so i wanna go with dash. I could put them where MissR34 has them, but i dont wanna remove the cigarette lighter because i have a GPS and things, and also it seems more dangerous to have them down there, harder to take a quick glance while driving

Air intake temp is pretty pointless, in my opinion.

I've got a GReddy Intelligent Informeter which pulls water temp, voltage and air intake temp from the OEM sensors (as well as a bunch of other data). You could get something similar if you actually want to know something rather than just ricing out your interior.

Then you could just get triple gauges for what the OEM ECU doesn't read, like oil temp, oil pressure, water pressure, A/F ratio.

I use one of these http://www.ecutalk.com/consultlcd.aspx

it is sitting under the lid of the factory tv screen that no longer works, just plugs straight into your diagnostic port and away you go. works very well

This might be a noobish question, but will this work if using a piggy back system such as the eManage Blue? I would imagine that the data coming from the ECU would be data before being remapped by the eManage and therefore probably wouldn't show correct data on the ecu talk... or am I mistaken? Looks like something I might add to my future mod list if it will be compatible.

I'm not entirely sure, I have a feeling it would read incorrect

In reality your best bet would be to fit the factory GT-t gauge cluster and put whatever aftermarket gauges in that you choose. It's a good location there.

Lol where would i get one of them from though? I dont mind cutting the trim, im sure i can do a decent job of it. But i might just mount the gauges as they come, they have their own mounts or i can buy a holder. I would prefer a holder, they look better, but if its that much harder then ill just mount them on the top dash with their stock mounts

      And finally, the front lower mount. It was doubly weird. Firstly, the lower mount is held in with a bracket that has 3 bolts (it also acts as the steering lock stop), and then a nut on the shock lower mount itself. So, remove the 3x 14mm head bolts , then the 17mm nut that holds the shock in. From there, you can't actually remove the shock from the lower mount bolt (took me a while to work that out....) Sadly I don't have a pic of the other side, but the swaybar mounts to the same bolt that holds the shock in. You need to push that swaybar mount/bolt back so the shock can be pulled out past the lower control arm.  In this pic you can see the bolt partly pushed back, but it had to go further than that to release the shock. Once the shock is out, putting the new one in is "reverse of disassembly". Put the top of the shock through at least one hole and put a nut on loosely to hold it in place. Put the lower end in place and push the swaybar mount / shock bolt back in place, then loosely attach the other 2 top nuts. Bolt the bracket back in place with the 14mm head bolts and finally put the nut onto the lower bolt. Done....you have new suspension on your v37!

      And now to the front.  No pics of the 3 nuts holding the front struts on, they are easy to spot. Undo 2 and leave the closest one on loosely. Underneath we have to deal with the wiring again, but this time its worse because the plug is behind the guard liner. You'll have to decide how much of the guard liner to remove, I undid the lower liner's top, inside and lower clips, but didn't pull it full off the guard. Same issue undoing the plug as at the rear, you need to firmly push the release clip from below while equally firmly gripping the plug body and pulling it out of  the socket. I used my fancy electrical disconnect pliers to get in there There is also one clip for the wiring, unlike at the rear I could not get behind it so just had to lever it up and out.....not in great condition to re-use in future.

      Onto the rear lower shock mount. It's worth starting with a decent degrease to remove 10+ years of road grime, and perhaps also spray a penetrating oil on the shock lower nut. Don't forget to include the shock wiring and plug in the clean.... Deal with the wiring first; you need to release 2 clips where the wiring goes into the bracket (use long nose pliers behind the bracket to compress the clip so you can reuse it), and the rubber mount slides out, then release the plug.  I found it very hard to unplug, from underneath you can compress the tab with a screwdriver or similar, and gently but firmly pull the plug out of the socket (regular pliers may help but don't put too much pressure on the plastic. The lower mount is straightforward, 17mm nut and you can pull the shock out. As I wasn't putting a standard shock back in, I gave the car side wiring socket a generous gob of dialectric grease to keep crap out in the future. Putting the new shock in is straightforward, feed it into at least 1 of the bolt holes at the top and reach around to put a nut on it to hold it up. Then put on the other 2 top nuts loosely and put the shock onto the lower mounting bolt (you may need to lift the hub a little if the new shock is shorter). Tighten the lower nut and 3 upper nuts and you are done. In my case the BC Racing shocks came assembled for the fronts, but the rears needed to re-use the factory strut tops. For that you need spring compressors to take the pressure off the top nut (they are compressed enough when the spring can move between the top and bottom spring seats. Then a 17mm ring spanner to undo the nut while using an 8mm open spanner to stop the shaft turning (or, if you are really lucky you might get it off with a rattle gun).

      You will now be able to lift the parcel shelf trim enough to get to the shock cover bolts; if you need to full remove the parcel shelf trim for some reason you also remove the escutcheons around the rear seat release and you will have to unplug the high stop light wiring from the boot. Next up is removal of the bracket; 6 nuts and a bolt Good news, you've finally got to the strut top! Remove the dust cover and the 3 shock mount nuts (perhaps leave 1 on lightly for now....) Same on the other side, but easier now you've done it all before

      OK, so a bunch of trim needs to come off to get to the rear shock top mounts. Once the seat is out of the way, the plastic trim needs to come off. Remove 2 clips at the top then slide the trim towards the centre of the car to clear the lower clip Next you need to be able to lift the parcel shelf, which means you need to remove the mid dark trim around the door, and then the upper light trim above the parcel shelf. The mid trim has a clip in the middle to remove first, then lift the lowest trim off the top of the mid trim (unclips). At the top there is a hidden clip on the inner side to release first by pulling inwards, then the main clip releases by pulling the top towards the front of the car. The door seal comes off with the trim, just put them aside. The the lighter upper trim, this is easy to break to top clips so take it carefully. There is a hidden clip towards the bottom and another in the middle to release first by pulling inwards. Once they are out, there are 3 clips along the rear windscreen side of the panel that are hard to get under. This is what the rear of the panel looks like to assist:
