Fair enough wrxhoon...I'm just repeating what Nismo said in their documentation

Nismo_SCMclutch02.pdf

Just under the bit where it lists all the parts in the kit.

Besides the clutch pedal is aready light with this clutch why would you want it any lighter?

I thought the nismo clutch was supposed to give you 'stock feel' and be very 'driveable'. I was hoping to get away from the on/off style of the old clutch. I guess i'll find out in a few weeks..... i

no it's the opposite. decrease in effort means decrease in travel too. basically it's a larger bore slave so for a given pedal movement it travels less distance now (but with less effort) that is the

I had one in my GTR. I could drive it fine after a few days but when I went to sell the car every person who test drove the car stalled the car 4-5 times trying to drive off. I warned people about it before they test drove and I would always drive the car 1st to show how easy it was but always got anwsers like "I drive race cars" , "I have a 500hp Rx7" etc and they thought they would have no problem. Then they would just stall it. and stall it, and stall it. Sometimes they gave up and I had to drive back. Ended up selling the the car to some 60 year old guy from up the sunshine coast

The reason I use it is because it gives you more feel . It says not to use a big operating cyl, I think they mean a much bigger cyl, the nismo cyl is only a little bigger than stock, ""Do not use with a big operating cylinder, which may result in a misshift due to insufficient stroke volume.""

Before I installed mine I asked a race team in Japan , they told me to use the Nismo cyl and I don't have any issues at all besides the normal rattle that all 6 speed getrags have. I also asked If we should use the carbon clutch, they told me not to use that for my application.

If you are happy with the normal cyl thats fine but I can assure you you will not run out of travel using the Nismo.

ant, I would just use it with the regular operating cylinder first and see how you go. wrxhoon definitely knows what he's talking about, but they do reccomend the coppermix to be used with the standard cylinder and not their nismo big operating cylinder. I did have one combo a few years ago with a twin coupled with a nismo cylinder and it sometimes did make gear selection difficult (mainly first). I thought it must have been stuffed, but I replaced it with a standard one and it was fine. turns out it just didn't have enough stroke for the given pedal movement to completely disengage the clutch. we are only talking the tiniest bit of difference but it was enough to make first hard to get sometimes when sitting still with the engine on (once moving it's not so critical).

Was that on a 32 GTR BB? The best way to test if you are running out of travel is reverse gear, if it crunches then you don't have enough stroke. Don't forget you can adjust the pedal as well. In my car I don't even have to use all its travel and she has a fair bit of free play too.

I have installed the Nismo cyl on both R33 and R34 GTR's ( several cars) without any issues, never had one installed on a 32 so I can't comment on that .

If you are happy with the stock slave stick with that but I have had both on my car and I prefer the Nismo slave, I still have my stock slave packed away .

yeah it was a 32 GTR. and yep, when stationary reverse and first hard to get. I didn't really notice it on the move as I think it was just trailing a tiny tiny bit of clutch.

I did still keep the nismo as a spare though too. and hey, it was only a 5 minute job to swap them, and 4 of those minutes was spent having a beer before swapping them over!

I bet it was the old push clutch .. Yea any monkey can swap slave cylinders, as it is lower than the master it will bleed itself too.

you saying i'm a monkey? ooohh ooog ahhh ahhh!!! and yeah it's push type.

NOOOOOOO....Just an example that is is a very simple swap mate ..no offence intended there BB..

haha, I know mate, just kidding around, none was taken. :blush: but it's true, if I can do it, anyone can do it!

lol twin plate clutch + daily driving = idiot. sheesh of course its going to be abitch to drive in traffic, wait till you wanna dog box then start moaning

my twin plate ATS carbon is unreal, i find it so easy to drive.

Hell even my sister and mother dont mind the clutch.

only issue i have with it is in the higher gears and no torque on the thing it rattles like a mo-fo.

I hv the HKS twins and so far the stalling practiced is over for me..been very good at traffic too. Hand brake helps a lot especially hill climb. I notice that when you feel that the clutch is about to bite and seeing the revs coming down, try holding the rpm slightly higher like 1100rpm.

The only problem i hv now is during normal or spirited driving i sense the pedal feels a kinda rough (jerky) when disengage during down shift. I bought the clutch 2nd hand from a friend who happened to changed new plates (both) before selling them to me. After 2-3 month using it as a daily driving, the problem starts. Now it's been 5 month and the pedal feel seem to get worst. I don't sense any slip during up shifting during spirited driving plus i never do a burn out / drag before.

Is the problem :

1) Is the clutch wear out already

2) Bad install

3) Slave pump (standard) need to upgrade to Nismo.

4) Fluid clogged

      7 Speed Auto transmission fluid change (Skyline, Q50, Q60, Fuga, Q70, A62 Titan and probably heaps of others including Navara...)

      By Duncan · Posted

      I thought I'd do a write up on an auto transmission fluid change for a the nissan 7 speed Automatic. At some stage the genius engineers decided that the fluid in the trans was "for the life of the transmission", (which seems kind of self supporting to me) and removed the dip stick and fill tube (funnily enough there is still a casting for it). Anyway, for this job you do need 2 specialist tools in addition to regular hand tools, jack and good chassis stands. You need a way to pump fluid up to the transmission; I got one of these but there are plenty of other options: https://www.ebay.com.au/itm/364584087070 Don't trust the generic listing though, it does not come with the required adapter for the Nissan 7 Speed. You need one of these, can't do the job without it: https://navarapart.com.au/product/genuine-nissan-patrol-y62-d23-np300-navara-re7-dipstick-fill-connector1 You need a heap of compatible transmission oil. Could be Nissan, could be anything else rated for Nissan Matic S. You need at least 10 litres, I had 15 to give it a better flush... Also, you need some biiig oil catch trays, at least one of these, or bigger if possible (volume was fine, size was very marginal): https://autobarn.com.au/ab/Autobarn-Category/Tools-%26-Garage/Specialty-Tools/Oil-Service/Garage-Tough-Oil-Drain-Pan-Black-16L---GT1068/p/TO03191 Finally, a measuring jug is very useful if your pump does not have volumes marked on it, I got a 6l one: https://www.repco.com.au/oils-fluids/fluid-accessories/measuring-jugs/penrite-measuring-jug-6l-pmj006/p/A5322648 Oh, and gloves.....this stuff is horrible (not as bad as diff oil, but getting there) ....First, jack up your car.....

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

      By Duncan · Posted

      So I mentioned the apprentice, @LachyK helped take the bonnet off. We just undid the nuts on the hinges and unclipped the gas struts, then pulled the bonnet back a little as the front was catching on the front bar.  I had a good look at everything today and have removed the rams, repaired/reset the hinges and bolted it back together like it never happened. I'll do a separate write up on the repair, and I also removed the poppers from the Fuga today too to save grief down the road.....as said above it is at least $5k to repair retail. I'm also happier about my ability to prepare a race car, and less happy about Nis-nault's engineering (I can hear @GTSBoy sAfrican Americaning) because the top hose of the radiator didn't slip off.......it snapped clean off. By practice I put the hose clamp hard up against the flare on a neck to make it least likely to ever move (thanks @Neil!). I guess that puts a little more pressure on the end of the pipe as it is further away from the rad, but still, that is pretty shit. I've put it back on for now as there was a fair bit of neck still there, but obviously there is no lip on the neck any more so I don't think I'll track it again until I have a new rad. Speaking of which....more research required. It looks like Koyo makes a standard size radiator in ally which I'll grab in the meantime, but I really want something thicker so might have to go custom in the medium term (ouch) Coolant still needs a refill and I have the pressure tester on it over night, but other than a wash down of the engine bay it seems alright. And @MBS206 noted something noisy on the front of the engine and I think I agree....time for a new accessory belt and tensioners I think.

      our good friends at nismo make a diff for it, I have one (and a spare housing to put the centre in) on the way. https://www.nismo.co.jp/products/web_catalogue/lsd/mechanical_lsd_v37.html AMS also make a helical one, but I prefer mechanical for track use in 2wd (I do run a quaife in the front, but not rear of the R32)

      R33 persistent issues. P/steering and lag/misfire

      By GTSBoy · Posted

      What are we supposed to be seeing in the photo of the steering angle sensor? The outer housing doesn't turn, right? All the action is on the inside. The real test here is whether or not your car has had the steering put back together by a butcher. When the steering is centred (and we're not caring about the wheel too much here, we're talking about the front wheels, parallel, facing front) then you should have an absolutely even number of turns from centre to left lock and centre to right lock. If there is any difference at all then perhaps the thing has been put back together wrongly, either the steering wheel put on one spline (or more!) off, and the alignment bodged to straighteb the wheel, or the opposite where something silly was done underneath and the wheel put back on crooked to compensate. Nut there isn't actually much evidence that you have such a problem anyway. It is something you can easily measure and test for to find out though. My money is still on the HICAS CU not driving the PS solenoid with the proper PWM signal required to lighten the load at lower speed. If it were me, I would be putting either a multimeter or oscilloscope onto the solenoid terminals and taking it for a drive, looking for the voltage to change. The PWM signal is 0v, 12V, 0V, 12v with ...obviously...modulated pulse width. You should see that as an average voltage somewhere between 0V and 12V, and it should vary with speed. An handheld oscilloscope would be the better tool for this, because they are definitely good enough but there's no telling if any cheap shit multimeter that people have lying around are good enough. You can also directly interfere with the solenoid. If you wire up a little voltage divider with variable resistor on it, and hook the PS solenoid direct to 12V through that, you can manually adjust the voltage to the solenoid and you should be able to make it go ligheter and heavier. If you cannot, then the problem is either the solenoid itself dead, or your description of the steering being "tight" (which I have just been assuming you mean "heavy") could be that you have a mechanical problem in the steering and there is heaps of resistance to movement.

      By MissMintyR33 · Posted

      Little update  I have shimmed the solenoid on the rack today following Keep it Reets video on YouTube. However my steering is still tight. I have this showing on Nisscan, my steering angle sensor was the closest to 0 degrees (I could get it to 0 degrees by small little tweaks, but the angle was way off centre? I can't figure this out for the life of me. I get no faults through Nisscan.
