SUNNY Z Posted April 29, 2010 Share Posted April 29, 2010 Just wanting to know, of the LS- 6 speed crowd, who is using what master cylinder. Pro's, Con's... All of my friends swear by Tick Performance's adjustable master, but I know there are plenty of others on the market. Also, if you could post pics of where you mounted / attached it, that would be helpful also. Thanks! Quote Link to comment Share on other sites More sharing options...

77turboz Posted May 2, 2010 Share Posted May 2, 2010 Tilton 7/8", stock mounting position I used a tilton 13/16, just because I found it on ebay off a nascar team. Barely used for $25 shipped. Quote Link to comment Share on other sites More sharing options...

RB30X Posted May 11, 2010 Share Posted May 11, 2010 So you used the standard 280zx clutch master on a T56 behind an LS1?? The reason I ask is I have an LS1/T56 conversion in my 240Z and when I tried to bleed the clutch master is started leaking through the seal into the boot and into the foot well. The master cylinder was a new factory item found in the Commodores/Clubpsorts over he is AUS which would be like the Camaro's/Corvettes over there. I pulled the master cylinder apart and cleaned out the plastic piston and the seals all looked good. Put it all back together and it still leaks. They don't just sell o-ring/seal kits here, you have to buy the whole replacement piston set which includes seals for $200 or a whole new master for $300. Anyone know or have a link to where seal kits are available in the States. I didn't want to spend that money to have it fail again, and was considering a older Z model clutch master. The question I have is about the volume of brake fluid displaced during the pedal stroke. The matching master seems to be quite small so I was hesitant to replace it with a older larger unit incase it opened the T56 slave cylinder 'too much' and damaged it. You obvioulsy have no dramas with it?? Just wasn't sure about matching different master cylinders to slave cylinders etc. cheers Quote Link to comment Share on other sites More sharing options...

So I used the 3/4" tilton unit-over 2 years with no problems. I used the 3/4 because that was the bore on the GTO cylinder. The tilton was around $70. There are a couple different models that work but one is more compact and allowed me to still use the stock washer bottle-of course that's on our LHD cars.

SUNNY Z Posted May 12, 2010 Author Share Posted May 12, 2010 Good info guys! Keep it comin! Side note: just installed a N.O.S. plate kit on the SBC. The fun is back in the car! Just jetted for a 100 shot...for now! Quote Link to comment Share on other sites More sharing options...
Boy from Oz Posted May 15, 2010 Share Posted May 15, 2010 I trust this is not too OT but I had intended to fit a GTO clutch m/s with my LS1/t56 install. I am concerned by the failures of these cylinders experienced by 'm1noel' and 'RB30X'. I've had a close look at the units and thought the problem might with the swivel connector on the line from the reservoir to the m/c, rather than the cylinder itself. Could either of those gentlemen advise me whether the leak was noticed in the engine bay or the cabin. Thanks. Quote Link to comment Share on other sites More sharing options...
RB30X Posted May 16, 2010 Share Posted May 16, 2010 (edited) Yeah mate, the leak was definetly in the cabin from the rubber boot, as in the piston seal was leaking. And for what its worth, my clutch pedal has a hole drilled a little higher up than the standard piston rod to reduce piston travel.

RB30X Posted May 22, 2010 Share Posted May 22, 2010 Pretty sure I've found the problem after stripping the MC for the second time. The piston was travelling too far foward allowing fluid to bypass the rear seal. I will either reduce the rod length which is already pretty adjusted, or increase the bump stop on the clutch pedal. Should be all sorted after that. Quote Link to comment Share on other sites More sharing options...

ragefear Posted May 23, 2010 Share Posted May 23, 2010 I hate all these stupid little issues I am having. I just got the Tilton 7/8" master and pedal assembly out of a standard Z, mine was originally auto. What are you guys using to attach the master to the pedal???

ragefear Posted May 29, 2010 Share Posted May 29, 2010 A bolt. really.... Actually I think I am going to do what you did. Mine didn't come with the rod end and when I posted that, I didn't know what it was called. lol. Quote Link to comment Share on other sites More sharing options...
