Hi, my name is Jeremy and I am in the middle of doing a 350/T56 swap in my Mazda RX7 but I'm having a problem with the slave cylinder.



With a project like this, it is usually the little things that set you back. Picture # 1 above is a picture of the factory GM hydraulic line that connects the GM clutch slave to the GM master cylinder. If you look at the picture above you can see the factory GM hydraulic line uses a pressure fitting (on both ends) to connect the clutch master cylinder to the clutch slave cylinder. Since I used a Willwood universal master cylinder (that has a threaded fitting) in combination with the GM slave cylinder (pressure fitting) I need to find a way to convert the pressure fitting to a 4AN or 6AN threaded fitting.

My first thought was to have the pressure fitting cut off the GM hydraulic line and then have a threaded fitting crimped on. I soon discovered that every place I found that makes custom hydraulic lines could not do this. There is a shop in Burbank California that makes a T56 to 4AN adaptor (picture # 2 above) with this adapter, but I have so far been unable to obtain the name of said shop. this adapter connects a threaded hydraulic line to a factory GM T56 clutch slave cylinder pressure fitting.

If anyone knows of a fitting like this, or perhaps an aftermarket slave that doesn't require that fitting it would be greatly helpful to me. This is my last hurdle I have to get over before I can take my car for a ride.

Thanks,

Jeremy

 

different t56s require different slaves. (LT1s have different slaves vs 2 different type of LS1 slaves depending on year) A little more information about the tranny might help people find the answer

 

It's out of a '95 z28 (LT1 style).
