Reply With QuoteThats not really the point of this thread, unless you are going to use a hydraulic release bearing with your Series 4/5 Rx7 box.
Personally though, knowing those Rx7 boxes, I would stick with the Toyota W Series, even behind a Rotary.
I'm gonna run a 4age silver top 20v and a rx7 fc s5 NA or turbo II transmission.. anyone done this before? Would this work in my ae86?

Just to update anyone who was curious how I went with my attempt to use the Howe hydraulic release bearing set up from my 1UZ W57.
I tried to transfer on to a W55 with A-Z customs adapter and T50 Bellhousing.
A-Z adapter is ~10mm thick, and this is why you have to use a pilot bearing spacer with it.
Combined with T50 Bellhousing I had to space the release bearing ~65mm to reach the pressure plate, and it did not leave enough collar for the bearing to sit on safely.
I would have to take ~5mm out of the bellhousing face, and still think it would not work right.
I ended up doing away with it and just used the JDM T50 bell with slightly modified T50 fork to clear the adapter studs.
I believe you could set up the Howe unit with a Nitesparts Bellhousing.
Ed from V-eight.com forums has a nice bolt in bracket that mounts off the input shaft cover for a quarter master unit.
This type of set up has the potential to work with A-Z set up, as it does not rely on the W series collar.

Hey Jimmy, I sent you a message about your adapter. Please email me at (I'm in the US). Thanks.
Digging up an old thread, has anyone ever looked at a concentric slave cylinder off a late Corolla? as in a genuine Toyota one?
I am going to get one in and check it out.

Hi guys, I tried putting a 4age with a t50 in my ke10 many years ago and after many set backs, the slave issue was the final straw. I would love to give it another go if I can source this adaptor you have made up for the SAAB hydraulic unit. I'm located in Australia and very interested....
I need an adapter
Do you still make the adapter for the saab release bearing? I need one for my t50....
Thanks
