Here's a little write up on how to install a boost gauge into the drivers side vent of an R32.

post-10239-1150443012.jpg

*disclaimer: If anything goes wrong or you break anything while following this post it's not my fault.

Items needed:

Phillips head screw driver

Socket Set

Spare vacuum line (the thin stuff that just fits the clear autometer tube inside it)

plastic T piece that fits the above vacuum line

Masking tape

Step 1

IMPORTANT Open the bonnet. It's easier to now than it is later

Remove the dash piece that's above the pedals and below the steering wheel.

- there are 4 screws along the top side

- 2 screws along the bottom side (32 gtst)

- 1 screw at the side (covered by the door when it's closed)

- 2 bolts that also hold in the bonnet release

n.b. Unplug the beeper after you've unscrewed everything (you'll see it when you do it)

Step 2

Once you've removed this piece you'll notice that the vent is attached. Unscrew the two screws holding it in and remove.

Step 3

Now what you'll notice is that you've got a nice little hole where you should be able to fit your gauge. Some fit, but with the autometer boost gauge that we had there was no chance of getting it in.

If this happens you need a Dremel. If you don't know what a Dremel is, maybe you should get someone that does and have them finish the install :P

Ok, now if you check the packaging that came with your autometer gauge you should notice that it came with a circular tube of hard cardboard in which it was placed. Get this tube and use it to see how much of the hole you need to widen.

Now with the autometer gauge I was lucky cause I basically just needed to shave off the clean rounded edge around the hole.

There was a lot to take off regardless. It's just this edge gave me something to work towards so that I kept the hole round, and didn't go too far.

Step 4

Dremel time.

I used this attachment.

Now here's where I wish I had taken more photos.

I didn't use this attachment to cut into the hole, I used it kinda like you would sand paper. Shaving away this inside of the hole slowly. TAKE YOUR TIME. Do NOT hack away at the hole, just shave the edges down slowly, moving around the hole till it's bigger.

Eventually it'll be big enough. Keep checking.

Step 5

Insert the gauge.

Here you can see the snug fit. It was actually so snug I couldn't get it back out again. So make sure you've lined it up properly before you push it all the way in.

Step 6

How the hell do you get the vacuum feed from the engine to the gauge??

Have a look in the engine bay.

post-10239-1150443392.jpg

The vacuum line highlighted by the red arrow is what we need to cut.

It currently feeds the stock boost gauge controller (the little box on the left).

Now look to the left a bit more and you'll see a hole.

This is your entrance into the cars cabin.

Here's the other side of that hole.

post-10239-1150443100.jpg

...and a bit closer. (Note I've already pushed the clear autometer tubing through the hole)

post-10239-1150443173.jpg

Step 7

Feeding the line.

- Grab an old coat hanger.

- Unwind it.

- Grab the clear autometer tubing.

- Line up the end of the tubing with one of the ends of the coat hanger wire.

- Tape around the end of the tubing and the wire tightly... make the end smooth and one piece basically.

- Get in the car.

- You see this rubber stuff?

post-10239-1150443173.jpg

- Poke a hole through it, then shove the coat hanger plus tube (taped end first) in through here.

- Now go and have a look in the engine bay.

- You should see the coat hanger and the tube in here.

post-10239-1150443315.jpg

- Grab it and pull it through.

Now that wasn't hard was it? Few mins and your done. So many people told me this step would take forever and was a bitch... sif.

Step 8

Attaching the Tpiece.

Cut the vacuum line pictured.

post-10239-1150443392.jpg

And attach the Tpiece.

Then cut the clear tube to size....

post-10239-1150443464.jpg

All done for the engine bay.

Step 9

Connecting the vacuum line to the gauge.

N.b. Ensure you leave enough slack in the vacuum line to get the gauge plus dash piece out again once installed.

Basically follow the instructions for you gauge at this point.

With autometer gauges, be careful not to twist or bend the clear tubing when screwing the attachment onto the gauge.

Step 10

Making it light up.

Grab the 12v feed from your cigarette lighter. It's the easiest 12v wire that goes "hot" when the headlights are turned on to find.

post-10239-1150443529.jpg

Wire this up as you would anything else. If you don't know how to do this, you shouldn't be installing the gauge.

Step 11

Admire your work.

hey guys im taking my boost gauge out (for regency) and need to plug up the t-piece so i can unplug it and re-install boost guage after. anyone know of a piece or 'plug' to do this?

thanks in advance

Also interested in a response to this question...Shogun did you have any luck?

Hi guys, I got a question regarding this install

My car's standard boost gauge does not work properly, on the stock gauge the boost starts at -7 rather than 0 and once on boost it goes up to 0 (rather than +7). Any ideas of what the problem could be?

Nonetheless, i am looking at installing a new boost gauge anyway and locating it at the driver's side vent as shown in this tutorial. Only one problem... My car doesn't have a cigarette lighter (a large pockets sits there instead), so i'm just asking if there are any other places i could wire up the boost gauge apart from the lighter?

Cheers

I did mine today, my gauge was smaller. Small enough to fit snuggly in the swivel-ball when I cut out the fins. Haha

I need to trim a little chunk out of the rear shroud to make it flush. You're tut is great and easy to follow. :-)

"Grab the 12v feed from your cigarette lighter. It's the easiest 12v wire that goes "hot" when the headlights are turned on to find."

I'm confused. What do you mean by "hot when the headlights are turned on"? Isn't the cigarette lighter power always on with ignition?

    • Nope.    Grab a varex and turn it down as you get close to home, win win? 
    • So, I've had my V36 for about a month now and have already copped an "excessive exhaust noise" notification from QLD TMR, reported by someone in my local area. It's a twin as per the original, and can have a bit of a throaty note to it when idling cold 😄 and if I do get up it a bit, it can be noisy, but it did pass a roadworthy inspection before sale, so.... ... but in the interest of being a good neighbour, I do want to quieten it down a bit. Is anyone here running a quiet aftermarket cat-back on their V36 or 370Z? And the big, bold question: does an aftermarket cat-back really make much of a performance difference on these cars?
    • The wiring diagram for the R33 RB25 is freely available, and is essentially the same same as most other RBs (just with differences as to which pin # does which job). To get the ECU to power up, you just need to provide power to the ECCS relay, and have the other power feeds that come in from the top left of the wiring diagram (wrt the ECU) that give perma power to the fuel pump relay, the ECU itself, etc etc, all connected. When you put power on all these it will just come to life. It's pretty clear from the diagram what needs to happen. Just follow the lines from the 12V + supply stuff in the top left over towards the ECU. I've even posted snips of such diagrams (not for vanilla 25, I think for Neo and 26) to various threads here in the last few months, talking about what it takes to get the fuel pump and FPCM up and going. Search these up and they will help get you started on doing the same with the vanilla 25 diagram. Hell, for all I know, I've done the same with that one in years past and have forgotten.
    • Yep...so unless someone posts up the answer you will need to probe from the ECU connector to the dash plug with a multi meter in continuity mode to trace the wires.  Note the ECU has multiple - and + (and across different key settings - Battery, IGN and Start) and most likely the power is fed from the connector(s) that is normally near the left hand headlight.
    • Thanks Duncan, I am actually just trying to get the Rb turning and running with the RB25DET S2 original loom itself  I am just trying to get it going outside the body and not thinking about the S15 or trying to match anything to the S15 loom at all I am only trying to see if anyone has done this and what pin they found to be the ignition trigger and ECU+/- on the dash connector, that's about it. Thanks
