This is for an R33, and is the way i done it for me and a few mates, if ya got a different car to the on ein ya avatar let me kno, i've done a fair few gauges now. ;)

Step 1: Locate vaccum line on back of intake manifold which if you follow is the only vaccum line goin off that part to in front of the driver in the top left corner of the engine bay where it goes into a small black unit which is the factory boost gauge unit.

Step 2: Cut this line half way and fit a t-piece into it.

Step 3: Fit extra vaccum line onto the t-piece and run it through the firewall hole near the factory bost gauge unit and down to near the drivers pedals (you'll have to really get under the steering wheel and shove ya hand up there and move the carpet to the side to do so. Once you find the line run it to where you want. (Don't use the nylon vaccum line supplied, only use it to connect the the black rubber vaccum line to the boost gauge at the gold fitting behind the gauge. Only about 6cm or so of the white stuff then throw the rest, it bends to easy and restricts the reading of the boost gauge as it comes all wound up with the gauge and is impossible to straighten without it bending anywhere.

Step 4: Fit the gauge cup to where you want the gauge to be positioned.

Step 5: With the wire coming off the back of the boost gauge, run the black to a solid ground, and run the red to the positive wire coming off the back of your cigarette lighter. This way when you turn on your lights at night, the gauge will light up also.

Step 6: Hide all the wiring and use convoluted tubing to hide boost gauge line and wires to make it neat and hidden. Fit gauge to cup and start boostn :(;)

I second that!

Just tryin to feed it through to under the steering wheel area and getting nowhere. I am feeding it through a hole just a little bottom left of where the throttle cable exits the firewall. Is this the correct hole? where is it suppose to come out? Or do I drill a hole lol.

Lol, Blast from the past dude but,

Yeah use one of the existing firewall holes, usually they have a rubber grommet you can run your line through, DONT DRILL HOLES !

You dont have to cut this....

Your gauge should come with

T-piece

Little hose for t-piece

vac line

gauge

So pull the line off, put in your t-piece. Put the line for the t-piece on and put it back in the same spot you pulled the vac line out off. connect vac line to other bit of t-piece then to your gauge. done

if it helps, there is a hole on the bottom right drivers side footwell (you'll have to pull back the kick panel) from this hole it feeds perfectly to were the factory boost sensor is (the little black box on the left side of engine behind the strut tower)

Sorry for my ignorance but what do you mean by kick panel? Is that the plastic cover just to the right of the throttle pedal that seems to cover a whole lot of wires on the side?

cheers

yep thats what i was referring to. there should be a screw at the back next to accelerator and 2-3 clips next to the driver side door - after you've undone the screw, a little bit of force and the panel should just pop out (be careful though).

you should see a fair few wires etc, gently push them to one side and look upwards towards the right - there should be a hole there. Obviously best to do it in the day light. If you cant see it, pop your bonnet - look at left strut tower - behind that there should be a black box (factory boost sensor) below that is where the hole should be (from memory)

ill take a pic if you want.

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
