Skyline R32 LS3 - Cluch Questions Hi!
Im building a Skyline R32 with a LS3 engine and T56 transmission.
If you want you can read more here:
Skylines Australia
And Im not from Australia, but from Norway
The reason for me to write here is that I have some questions.
1. What is the recomended size of Clutch Master Cylinder?
I am using a Pedal box, as this is a track car only, but I do not know the recomended Size. Choices are:
2. What clutch is recomended for use in racing?
Since Im going for aproximly 550-600rwhp and 550-600lbsft torque, and using it to drift with, witch is a tremendusly hard on the clutch, I was wondering if I should use a dual plate like Fidanza Twin Disc Clutch Kits, http://store.summitracing.com/partde...5&autoview=sku
Or do anyone else have a recomandation?

For any kind of stock clutch set up ou need at least 0.75" and you don't want more than 1.00" bore. As for the stroke, I would get the longest you can and use a stop to reduce the travel if necessary.
Sounds like a fun car.

That thing is going to be serious

run what most of us run a 1" stroke .750 bore. im using a wilwood master on mine and its worked fine (except for when a master failed 5 months into the swap)
as for a clutch, just get a GOOD sprung puck setup from somebody like RPS or McLeod. im making about 400 at the wheels and am running a spec 6 puck and have never had a problem. car is a full on drift car.
p.s. you wont be using the clutch as much as you think with all that torque
i rarely have to clutch kick anymore haha

Hi!
Thanks for the help.
Currently there seams to be three to choose from:
Bore: 0.625in, Stroke: 1.300in, Volume: 6.54ml
Bore: 0.750in, Stroke: 1.100in, Volume: 7.96ml
Bore: 0.875in, Stroke: 1.200in, Volume: 11.82ml
There is a lot more volume difference between the second and third choice than the first and second.
The first has a long stroke, but a realy small bore, but the second has a short stroke but ok bore.
Thats why I was thinking of the third one, wich has a long stroke, and big bore.
But remember, Im probarbly going to run a racing twin plate clutch setup for a LS7 or something like that.
What do you think?

I'm running the 0.75" wilwood for my LSx 240sx project. And just drove RuthlessLS2's with the same master. His with a blown stock clutch was coming on quite a ways off the floor. So I don't think that I'd go bigger.

I just found another cylinder from wilwood that I can use, it has 1.4" stroke, and 0.750 bore.
and It ads up like this:
Bore: 0.625in, Stroke: 1.300in, Volume: 6.54ml
Bore: 0.750in, Stroke: 1.100in, Volume: 7.96ml
Bore: 0.750in, Stroke: 1.400in, Volume: 10.14ml (The new one)
Bore: 0.875in, Stroke: 1.200in, Volume: 11.82ml
I would think this is big enough in volume to handle a racing clutch, but sensitive enough because of its small bore and long stroke.
What do you people think?
I like the sound of this project.

Hi everyone!
I would prefere that all questions about the build it self is done in this thread:
Skyline R32 LS3, Build Thread
Since this thread is only about what Clutch Master Sylinder to chose and Clutch to choose.
The other thread also contains a lot of pictures...
