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.

Thanks mate. I think I get ya. I'll have a go next time I have day light and time after work. If I am still lost I'll ask for a pic!

hope this helps everyone / anyone (if i've made a mistake someone correct me)

the pipe below is where i spliced a small section out (no more than 5mm) i put the T piece in, connected the spliced pipe to either end of the T piece, attached piping from the last hole on the T piece which on my boost gauge (2nd pic) will connect to the new boost gauge sensor.

pic of the boost gauge (autogauge from just jap for those playing at home)

pic below is a mock setup of the boost gauge - im guessing most gauges these days come with the small circular filter (top right in the pic below) I cut the tube going from the black boost sensor to the T piece about half way - attached the filter (helps to smooth out the movement of the needle on the boost gauge / stops dirt/crap flowing back into the boost sensor)

lastly, pic of the location of the hole i used to run the tubing / wiring in under the drivers side kick panel then up through the steering wheel / under the dash etc ready to be wired up to the cig lighter / ignition etc.

Ok, intensely frustrating. I took the kick board off and tried to feed the line through down there... no sign of it. So I took a box off with the letter "J" and looked behind it and it seems like an inclosed panel with a wall where my line should be coming through.

Hmmm. Is the reason that I cannot find it because I am using a bendy/curly bit of pipe that came with the gauge? It may not be reaching down there.

Am I looking in the right place?

cheers,

Dan

P.S. Thanks for the photos! Though I think the connecting the T bit seems the easy part.

Hey defari,

Looks like we lost those last few posts! I am still keen for that pic. As I said in the wiped post, the furtherest I got was getting it into the side panel behind the wheel. I am guessing this is not the route because I could find no way through to the foot-bay area.

thank you for your time!

the grommet you can use is one the right hand side of the accelerator pedal and the bonnet release cable goes through it, just peel back the sound deadener and then put it back once the line is fed, then in the engine bay use some pointy nose pliers to grab it. the hole is pretty much in between the firewall and the drivers side tower, oval shape hole.

another thing i reckon looks good if you mount your gauge up on the dash is running the vac/boost line through the dash via a small hole. ill post a photo tomorrow, looks pretty neat and you can do the same with oil pressure gauge.

FINALLY! After much toil and suffering, it is done!

I sent it up through the bonnet release catch's grommet and managed to find it and pull it through to the engine bay. For others who try to do it this way... the grommet that the bonnet catch runs through must have a sock-like thing that the cable runs through after the grommet. I tried for ages to push the vac/boost line through but it always only made it a couple of cm and wouldn't go any further. I pushed a number 8 wire up there in the end and poked a hole through the sock and then sent the vac/boost line up through that hole (I had to push and feel for it). I hope there isn't anything wrong with doing it like that...

Glad that nightmare is over for such an apparently simple process.

I thought this was going to be easier than it has turned out. I just can't get my fingers (or pliers) down to grab the wire I stuck through from the cabin. Attached image shows where I'm looking. I just can't get it. Is there a way to find it from in the wheel well and poke it up? I had envisaged it just being a grommet on a clear spot of the firewall but noooo.

Old thread, but I'm hoping people are still using this valuable information - I did my Autotechinca boost gauge today for the first time as a bit of a trial and could not have done it without this information - take a bow sir.

p.s took me all f$@&ing day haha

Thanks!

    • 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.
    • Hi,  Just joined the forum so I could share my "fix" of this problem. Might be of use to someone. Had the same hunting at idle issue on my V36 with VQ35HR engine after swapping the engine because the original one got overheated.  While changing the engine I made the mistake of cleaning the throttle bodies and tried all the tricks i could find to do a throttle relearn with no luck. Gave in and took it to a shop and they couldn't sort it. Then took it to my local Nissan dealership and they couldn't get it to idle properly. They said I'd need to replace the throttle bodies and the ecu probably costing more than the car is worth. So I had the idea of replacing the carbon I cleaned out with a thin layer of super glue and it's back to normal idle now. Bit rough but saved the car from the wreckers 🤣
    • After my last update, I went ahead with cleaning and restoring the entire fuel system. This included removing the tank and cleaning it with the Beyond Balistics solution, power washing it multiple times, drying it thoroughly, rinsing with IPA, drying again with heat gun and compressed air. Also, cleaning out the lines, fuel rail, and replacing the fuel pump with an OEM-style one. During the cleaning process, I replaced several hoses - including the breather hose on the fuel tank, which turned out to be the cause of the earlier fuel leak. This is what the old fuel filter looked like: Fuel tank before cleaning: Dirty Fuel Tank.mp4   Fuel tank after cleaning (some staining remains): Clean Fuel Tank.mp4 Both the OEM 270cc and new DeatschWerks 550cc injectors were cleaned professionally by a shop. Before reassembling everything, I tested the fuel flow by running the pump output into a container at the fuel filter location - flow looked good. I then fitted the new fuel filter and reassembled the rest of the system. Fuel Flow Test.mp4 Test 1 - 550cc injectors Ran the new fuel pump with its supplied diagonal strainer (different from OEM’s flat strainer) and my 550cc injectors using the same resized-injector map I had successfully used before. At first, it idled roughly and stalled when I applied throttle. Checked the spark plugs and found that they were fouled with carbon (likely from the earlier overly rich running when the injectors were clogged). After cleaning the plugs, the car started fine. However, it would only idle for 30–60 seconds before stalling, and while driving it would feel like a “fuel cut” after a few seconds - though it wouldn’t fully stall. Test 2 – Strainer swap Suspecting the diagonal strainer might not be reaching the tank bottom, I swapped it for the original flat strainer and filled the tank with ~45L of fuel. The issue persisted exactly the same. Test 3 – OEM injectors To eliminate tuning variables, I reinstalled the OEM 270cc injectors and reverted to the original map. Cleaned the spark plugs again just in-case. The stalling and “fuel cut” still remained.   At this stage, I suspect an intermittent power or connection fault at the fuel pump hanger, caused during the cleaning process. This has led me to look into getting Frenchy’s fuel hanger and replacing the unit entirely. TL;DR: Cleaned and restored the fuel system (tank, lines, rail, pump). Tested 550cc injectors with the same resized-injector map as before, but the car stalls at idle and experiences what feels like “fuel cut” after a few seconds of driving. Swapped back to OEM injectors with original map to rule out tuning, but the issue persists. Now suspecting an intermittent power or connection fault at the fuel pump hanger, possibly cause by the cleaning process.
