I have always found Coz's shipping prices quite good.. compared to somewhere like courtesy Nissan, they are an absolute bargain... I have never ordered anything large or heavy though

lol how did you get shipping so cheap?

I spoke to Coz numerous times in the past/// I found his shipping quotes to be ridiculously expensive...

did you bargain the shipping down?

my order was for an exhaust, the same one on ebay cost half as much as Coz's to ship.....

comparing around, I found ebay shipping still to be the cheapest.....

do you know if Coz combines shipping??

Yes he does combine shipping, i got everything at $575 shipping i don't know how it's so cheap but he must have ties with USPS or something to do it that cheap. Either way, i'm not complaining he's done me a pretty damn good deal

OK - thought i'd post back here my results after getting the new CD009 gearbox, southbend clutch & flywheel installed.

The bloke that was doing it for me had everything installed by 5:30, (gave him the car at 9am) then as he went to adjust the clutch found a problem. The pivot ball was the wrong size. The standard pivot ball from my 03 is short. The pivot balls from the 04-07 is a long version and it WILL NOT allow you to adjust the clutch correctly. The gearbox had to come out AGAIN to change the pivot ball back to the original one.

Now for the positives - the CD009 gearbox feels amazing paired with Amsoil gear oil. Shifts are very smooth and easy to engage, compared to my old beat to shit gearbox. It was funny when i originally bought the car i was told it had a HD twin plate Exedy clutch, i took his word because i noticed it was quite heavy and 12 months ago i didn't know nearly as much as i do know about cars and parts... Turns out it was just a single plate HD exedy clutch and also a exedy flywheel.

I have encountered a slight problem when driving it home last night and this morning to work. The clutch is making a noticeable rubbing or grinding sound when i am accelerating and changing gears. The same noise is barely noticeable when the car is at idle with the clutch in, i don't beleive it's the flywheel because that makes a different sort of chatter which i can also hear when i accelerate from a stop. But the aftermarket Southbend flywheel is steel and it actually seems to make less chatter than the standard exedy flywheel that was in it which is good.

Does anyone have an idea on what this noise would be? I am taking the car back to the installer in a couple of hours so he can diagnose it but thought i'd ask the question.

It should be the clutch bedding in, ask the dude, but he should have told you how to drive it for a thousand km or so. You know, no excessive slipping, no side stepping etc.

Yea ok cool thanks Alex, for sure i have every intention of taking care of the new parts. I had the idea it might be air in the lines, there has been SS clutch lines installed too. Just sounds a little squishy but it doesn't feel spongy at all it's nice and smooth when i engage.

Ok so i went back to the shop and got the bloke to check it out for me, he had a drive and noticed it too. It's sort of a rubbing sound when the clutch is engaged and accelerating, he thinks that it's because the Southbend clutch is a mix of copper. If you press the clutch in for longer than about 3 seconds the noise stops. Been doing research on g35driver.com about the Southbend clutch can't seem to find a great deal of information but i'll keep looking. I'll also get back in touch with Coz from ConceptZ who sold the box and clutch to me and see if he knows.

Anyone have an input about the copper mix southbend clutch gurgle sound when engaged? I contacted Coz again from CZP and he said to drive it 500 miles then get back in contact with him but other than that he has never heard of this sound with the southbend clutch and flywheel setup. Is it possible the bleeding of the clutch fluid was done incorrectly? i got brand new fluid in there. Cheers

If the bleeding was bad you would get a bad pedal feel, and it wouldn't fully disengage. I've driven a nismo single coppermix, and it does make noises, as people with the nismo twin have also described. Coz is right, drive it for a while and your figure what's normal and what's abnormal. Don't expect it to be a stock one, it's uprated.

do the noises sort of match up to the sounds that you heard from the nismo clutch? Yeah certainly, i do realise it's aftermarket and it will be different the only thing that's odd is that Coz has mentioned he's never heard of it happening with the setup or else i'd just be cool with it and get used to it. I just hope it's not a faulty clutch, that would be a PITA

I've never heard a southbend. To be honest, I haven't heard enough clutches to know confidently if it would be normal.

But this is what I'd do. Continue to bed it in for the 500 miles. Then gradually lean on it more and more until you give it heaps. If it survives, it will be fine. Stop worrying and get a louder exhaust. :P

Out of curiousity, have you driven a lot of cars with upgraded clutches? The first few times when they're bedding in, it seems weird and unnatural. After that, it's all good. Maybe the southbend is a noisier clutch and that's what you're hearing?

Yeah i hadn't either before i bought it but i was highly repped by the guys in the states, and being built by Exedy it's meant to be quite good quality. Exhaust is next on my list, don't worry! haha.

I drive a shit load of different cars all the time in my work but never really ones with upgraded clutches. I've driven my mates Evo 6 before which is very stiff but that's about it. I'm hoping this is the case, i can't notice the sound when i've got music on so i think i'll just let it run in for about 1000km and forget about it unless i read something on the net about this sound and go from there.

Coz emailed me back- He said that the organic Southbend clutch is very similar to OEM and should not make any different noises. He thinks that it's something to do with installation because as i said before he's never heard of this issue with the Southbend setup. The guy that fitted it all for me is out at work for 5 days i think so i'm not sure if i should wait 500km+ to see if it goes or take it straight back to him and get him to check how it's all setup.

    • 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.
