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.....

if the larger nismo slave decreases pedal effort, it should also slightly increase the amount of pedal travel from disengaged to engaged?

hey vspec, the pedal feel is very light (i have a larger slave and nismo twin), but yeah the clutch is quite an on/off sort of one, me, and all my mates stalled it a few times, but im getting used to it, there is a bit of slack there, but not much, you need to give it a few good revs to get it to go, nothing big though, im used to it now.

P.s: yes i also though when people said that the clutch feels like stock, that they meant in pedal feel,and in progression between engaged/disengaged, the later is not true:)

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 reason I went back to a stock slave.

So with the larger slave, progression is lost, but pedal feel is heavier?, that makes sense,mmm.....maybe is should go back to stock slave and see how it feels....not too hard to do i guess???, willl need to bleed the clutch again though.

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 reason I went back to a stock slave.

Ok looks like i might leave the standard slave in as long as its not too heavy.

I was imagining it like changing the pivot point, giving it move leverage. Lighter feel and and more pedal movement reqd to do the same work(but with less effort)

Hydraulics i'll admit i dont know too much about....

I think some of you have misunderstood. :D

The way I understood what Beer Baron said was:

With the larger slave cylinder you decrease clutch movement for a given pedal movement which results in a lighter pedal (due to increased leverage) but also less clutch travel.

Reduce clutch travel and the take up point will be super close to the max pedal movement (i.e the floor); which can be a bad thing depending how close the take up point is to the floor as it can increase the frequency of missed gears or crunching when shifting fast.

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 reason I went back to a stock slave.

You could have ajusted your rod so you get more travel, if you was running out of pedal travel .

The bigger slave is much better , less effort and more progresive.

Nismo twins are about the best you will find as far as driveability goes .

Don't forget you will never have the same feel as a normal stock clutch , what you hvae is heaps more grip and lighter pedal in twin plates ( if you compare same clamping single and twin the twin will be lighter). The other reason you stall your twin is the much lighter flywheel, you have better response but you loose out on the torque of the much heavier stock flywheel. You can't have it both ways but a twin will take a lot more punishment and it will last as long as you DONT ride it , ride a twin and you will wear it out very quick, especially when you ride it between gears ..

yeah what cubes says is correct. nismo slave gives lighter pedal, but less travel for a given pedal movement. stock slave is heavier pedal but more travel for a given pedal movement.

wrxhoon, I did adjust the rod at the pedal, and maybe my nismo slave was a bit worn (it was on the car when I got it). it wasn't leaking though. anyway the pedal effort is not too bad with stock slave (that's with both my OS twin, and my OS tripple). as you pointed out to get a heavy duty single to grip they need massive pressure plates, you can have a twin hold the same power with a ligther cover pressure so to me the pedal is not too bad at all even with stock slave. :blush:

OK now i'm confused :blush::)

more progressive means less on/off switch style performance right, thats what i'm after....

Heres a pic that help explains what i'm trying to figure out:

"you need to drive it hard when you see it play up"??

I don't even know what this means...

You will need at least 1000k's to break it in....

Then you will need to drive hard every time you see it playing up.

Referring to uneven clutch plate wear perhaps?

I never experience it with my twin plate in the 180, but when the clubbie starts squealing it's button I just slip it from a 3rd gear launch to even it out again. It works a treat.

Don't know if it helps any but I've driven R32's with the following clutches: OS Giken TS2CD, R3C, STR2CD, TR2B-C ( Carbon Twin Plate ) and NISMO Coppermix and all were very grabby when they get warm ( STR2CD being the best of that bunch and R3C being the worst ).

You just have to get used to it :rolleyes:

First few days I had my Nismo twin I thought it was horrible, I wanted my old standard and very worn clutch back :rolleyes:. Its still not broken in yet and is still quite annoying and embarrassing doing the hops away from lights but I am getting used to it. I get heaps more bumps and knocks coming from all over the car, probably the diffs clunking and engine mounts straining....

Can't wait to give this thing a 7k launch at the drags :(

hahaha, i know what you mean, its so hard to get used to,im slowly getting used to it though:). Hill starts are the worst for me, i cant count the no. of times i have stalled on a semi steep hill, its embarassing yeah, but those guys have no clue what i have to drive hahahaa

ive driven with twins, singles, super singles and use a triple in the gtr

they are all different and nothing is too hard to live with, you just have to deal with it...

saying that the triple is actually the best clutch i have used, twins tend to be very bitey

the worst clutch i ever used was a 3 puck solid centre single. was very light but was litterally a clutch dump at 3500rpm or stall

My 33 had an exedy twin plate in when i collected it, and the drive home was hell! Looked like such a d!(k over revving and stalling this line all over the place. But now i'm use to it and its great! Just need to use handbrake starts on any hills.

But after driving a mates 34 with stock clutch I would never go back, when you can use a tuff clutch it makes driving that much better.

lol yeah, i have an orc twin plate in my 32. took me a little while to get used to it, peak hour, and hill starts ftl... that being said i would not have it any other way...

"i call the big one bitey"

I think you guys need some serious driving practice. I haven't driven a clutch yet I couldn't get the hang of within half an hour.

I my own cars I've had standard, nismo single, heaving duty exedy single, OS twin (solid centre) OS tripple (solid centre) and quickly adapted to all of them. I've also driven tilton twin, carbon single, and various twins, singles and tripples.

with my OS tripple I never stall it, can do hill starts no problem. even with a small 'take up zone' all you need is a small amount of clutch control to drive it easily. so practice up.

A friend of mine with a Nismo twin plate of some kind says all Skyline drivers should stall at least once every time they drive the car.

ha ha! I like that

I always stall my TS2BD when I am tired and not concerntrating, but apart from that it is fine, and Im with Barron, the stock slave make the clutch easier to use IMO

    • Yea that’s why I said ima test them with multimeter and see the reads.
    • Only at idle. Isn’t a problem when rev it seems.
    • @Haggerty This seems silly to ask, but are you confident in your ability to tune the Haltech?  
    • Next on the to-do list was an oil and filter change. Nothing exciting to add here except the oil filter is in a really stupid place (facing the engine mount/subframe/steering rack). GReddy do a relocation kit which puts it towards the gearbox, I would have preferred towards the front but there's obviously a lot more stuff there. Something I'll have to look at for the next service perhaps. First time using Valvoline oil, although I can't see it being any different to most other brands Nice... The oil filter location... At least the subframe wont rust any time soon I picked up a genuine fuel filter, this is part of the fuel pump assembly inside the fuel tank. Access can be found underneath the rear seat, you'll see this triangular cover Remove the 3x plastic 10mm nuts and lift the cover up, pushing the rubber grommet through The yellow fuel line clips push out in opposite directions, remove these completely. The two moulded fuel lines can now pull upwards to disconnect, along with the wire electrical plug. There's 8x 8mm bolts that secure the black retaining ring. The fuel pump assembly is now ready to lift out. Be mindful of the fuel hose on the side, the hose clamp on mine was catching the hose preventing it from lifting up The fuel pump/filter has an upper and lower section held on by 4 pressure clips. These did take a little bit of force, it sounded like the plastic tabs were going to break but they didn't (don't worry!) The lower section helps mount the fuel pump, there's a circular rubber gasket/grommet/seal thing on the bottom where the sock is. Undo the hose clip on the short fuel hose on the side to disconnect it from the 3 way distribution pipe to be able to lift the upper half away. Don't forget to unplug the fuel pump too! There's a few rubber O rings that will need transferring to the new filter housing, I show these in the video at the bottom of this write up. Reassembly is the reverse Here's a photo of the new filter installed, you'll be able to see where the tabs are more clearing against the yellow OEM plastic Once the assembly is re-installed, I turned the engine over a few times to help build up fuel pressure. I did panic when the car stopped turning over but I could hear the fuel pump making a noise. It eventually started and has been fine since. Found my 'lucky' coin underneath the rear seat too The Youtube video can be seen here: https://www.youtube.com/watch?v=uLJ65pmQt44&t=6s
    • It was picked up on the MOT/Inspection that the offside front wheel bearing had excessive play along with the ball joint. It made sense to do both sides so I sourced a pair of spare IS200 hubs to do the swap. Unfortunately I don't have any photos of the strip down but here's a quick run down. On the back of the hub is a large circular dust cover, using a flat head screw driver and a mallet I prised it off. Underneath will reveal a 32mm hub nut (impact gun recommended). With the hub nut removed the ABS ring can be removed (I ended up using a magnetic pick up tool to help). Next up is to remove the stub axle, this was a little trickier due to limited tools. I tried a 3 leg puller but the gap between the hub and stub axle wasn't enough for the legs to get in and under. Next option was a lump hammer and someone pulling the stub axle at the same time. After a few heavy hits it released. The lower bearing race had seized itself onto the stub axle, which was fine because I was replacing them anyway. With the upper bearing race removed and the grease cleaned off they looked like this The left one looked pristine inside but gave us the most trouble. The right one had some surface rust but came apart in a single hit, figure that out?! I got a local garage to press the new wheel bearings in, reassemble was the opposite and didn't take long at all. Removing the hub itself was simple. Starting with removing the brake caliper, 2x 14mm bolts for the caliper slider and 2x 19mm? for the carrier > hub bolts. I used a cable tie to secure the caliper to the upper arm so it was out of the way, there's a 10mm bolt securing the ABS sensor on. With the brake disc removed from the hub next are the three castle nuts for the upper and lower ball joints and track rod end. Two of these had their own R clip and one split pin. A few hits with the hammer and they're released (I left the castle nuts on by a couple of turns), the track rod ends gave me the most grief and I may have nipped the boots (oops). Fitting is the reversal and is very quick and easy to do. The lower ball joints are held onto the hub by 2x 17mm bolts. The castle nut did increase in socket size to 22mm from memory (this may vary from supplier) The two front tyres weren't in great condition, so I had those replaced with some budget tyres for the time being. I'll be replacing the wheels and tyres in the future, this was to get me on the road without the worry of the police hassling me.
