I'll have some pics tomorrow probably. Going to go down (all 500 metres away speedworks are from my work) and take some pre-install photo's and trust intercooler goodness... *droool* Hey dave where can I get some of that thermo tape wrap stuff... I might wrap the pipes before they go on? and then do the dump pipe/front pipe to cat when thats done too. Might be an idea to actually wrap some tape around that pipe that goes into the manifold over the engine that seems to get damn hot.

Steve,

It makes sense, the factory one has a small air bleed (hole on the underside) people  mistake for the factory BOV not holding boost at light cruise due to it being so-called 'too lightly sprung for high boost apps'.  

There is someone with a thread about blocking the hole off on the performance section!

I got rid of my stocker BOV for a couple of reasons. For starters the 32's have a recirc pipe the plumbs back into the intake at a point which makes the standard BOV incredibly loud when fitted with a pod filter (most atmo BOV's would be quieter). Secondly, mine used to vent at very very mild throttle adjustments, you could be cruising along the freeway and even mild 5km/h increases in speed, throttle feathering and such produces a loud "PSSSSCCCHHHTTT" sound. Not to mention a horrible rushing air noise when on boost (you couldnt hear the turbo spool or even the engine over it).

It was just plain embarassing. I couldnt drive it sedately without a massive BOV noise on every gearchange. Least the TurboXs one i have now is quiet until you start changing at over 3000rpm. And you can hear the engine note and turbo spool clear as day.

Mine did the same thing, and that simple BOV mod stops that.

I found it frustrating too :D

Now it only opens when there's a decent amount of preasure difference - not 10psi+, but enough not to open at stupidly low boost.

Ok, here are some pre-install pics of the trust cooler. Its a 600x244x76mm core (tube and fin core) as you can see from the photo's its designed to use the standard intercooler pipes in the engine bay (which I think I'll replace at some stage with trust polished aluminum ones anyway). The pipe below the cooler flows from the left side to the right side and up into the engine bay, however if you went for the trust plenum I'm sure you could adapt the piping up the left side of the engine bay. Its going in next wednesday (and the cars getting a much needed service). I'll try and get some pics of it being installed (just walk down to speedworks in my lunch break) and then some more pics once its installed, looks like we'll have to trim some of the stock front spoiler to give more airflow to the cooler. Anyway... enjoy :rolleyes:

Although I have had parts shipped to work so the mrs doesnt find out :D

hahaha ... nice :rolleyes:

That cooler looks sweet man ... should be good when it goes in.

You'll have to take some after shots so we can see it :D

Yeah, will do. Looking forward to getting it in, I wont be running 0.8bar all the time but it'll sure help when I am. You gotta remember though this will be around $3k fitted all up, you gotta be thinking about whether jap stuff is really worth that much when you'd probably get a good aussie job fitted for $2k. Should be more than enough for 450-500hp, which I'll never get to... rather buy a GTR :rolleyes:

    • 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.
