R154 Supra Transmission Adapter?

Does anyone know where to get a transmission adapter for this transmission to a mazda rotary? I've looked all over the Australia sites and can't find who makes one. The top 5 Australian cars running with OEM transmissions are using the Supra transmission http://ausrotary.dntinternet.com/for...ic.php?t=46604

Does the input shaft on the R154 tranny have the same spline count as the TII RX-7 tranny? If it does, then you can use clutches that fit TIIs.

If the spline count is not the same, then you have to use Supra clutches. Are Supra clutches 240mm?

You have to get a clutch made that is the supra spline and is 240mm and I already looked into it and it's not that expensive.

This is awsome, great find ! Where are you getting the clutch done at? Is it a single plate? And what was the cost? Also what about the v160 (the 6 speed) has anyone tried that ?

There's a local clutch/transmission shop near my house and they can get any disc made I just need to tell them what spline and diameter the disc needs to be and what material I want it in. Don't have pricing but the guy at the shop said under $200 probably closer to $100. I'm going with a six puck solid disc for my car. Only problem now is I contacted rotorworx in Australia and they said they don't deal overseas but I'm going to post in Ausrotary and see is anyone can get it sent over here. I'm just glad to know that someone makes it.

Maybe we can do a small group buy? I'm interested in the turbo adapter and the shift linkage. Also thats funny they dont deal overseas, on their site it says they ship their engines worldwide lol. Have you talked to them about mounting? What other extras are their?

What about the shaft going from the tranny to the rear diff? Does the stock RX-7 shaft fit or does that need to be a custom shaft?
