Tranny
- but then again, I'm probably going directly to the JUNK MAIL folder, haha
Classic!
So please bear with us guys, cuz while I know no one likes waiting, if this thing goes through as planned, it's gonna be one nice sick deal that'll pretty much solve all your needs from the bellhousing to the diff
Thanks!

Dave, I realize that although you're jokin around, that there's def. a level of seriousness in your comment. So allow me to just state for clarity's sake that this is not gonna happen overnight guys. We're trying to take out ALL the guesswork for you guys, as well as line up some deals on ALL the parts necessary - many of which will cost *significantly more* if you don't have a discounted price already lined up - which is what we're trying to offer. Parts like the clutch, flywheel, trans, and possibly driveshaft (and a few smaller misc parts like the starter, Tilton parts, etc).

Are you sure you want to offer a driveshaft? I'd think there are too many variables to try and cover all the bases and custom driveshafts are easily sourced. You guys would know best though.
Is there any possibility of guesstimating a timeframe for this to come together?
Haha I figured as much
It'll def. be one of the options, but a twin plate will be available as well, as most ppl don't have almost $4K to blow on a clutch But I can tell ya, it looks like there are at least 3 ppl getting the triple plate cf
Cool.
We will see. I'm throwin it out as a possibility, that's all.
Soon 
Tilton carbon triple plate please.

I'm probably the only FC guy interested in this. That said, I won't be needing a transmission mount or driveshaft. Also, since I'm moving the tranny back 6", I won't need the tripod shifter mount either.

There is no setup I could think of that would necessitate you to get a Getrag tranny but be able to run a single plate clutch. If you're running enough power to need a Getrag, you won't be able to use a single plate; you're already in the twin plate (if not triple plate) territory.

Very nice work Carlos....and it's good to hear you are doing better health wise. I'm a little late coming into this thread and had a few questions regarding what was included in the kit. If I was to purchase the kit what items would be need to be purchased to get up and running with a Supra tranny? I assume the transmission itself, clutch and flywheel are needed. How available are the transmissions and at what cost? I guess I would like to know the final numbers before going forward. Thanks again for the engineering on this. It looks like the only transmission many of us would ever need.
Thanks,

You will destroy a Getrag doing the same, I guarantee you. It's still a sychro box. If you wanna shift faster than the synchros, you'll need a dogbox or dogrings in the FD tranny. Either or, synchro boxes aren't for ripping thru gears. I'd hate to see you spend ALL this money on a trans, adapter, clutch, flywheel, etc, then destroy a tranny that is VERY expensive to rebuild...
I'm pretty sure there are several people who have wyorked out the T56option.... the reason for the getrag (and all of the rest of this kit) is to handle the potentialy high RPM shifting of the rotary as compared to an Lsx motor. The consensus as I understand it is that the T56 *can* shift that high.... but will not last *if* shifted that high. The getrag has settled out as the best options to handle all requirement....
As excited as I am a great solution has been found to support 20b power and shifting, the never ending costs are making it increasingly hard for me to justify the price of a built 20b over an Lsx....
I love the novelty of the 20b, and have been willing to pay for it.... up until recently when my wallet is saying I should consider elsewhere. who knows what I'll do.-Chris

We have road race setups and the stock gearing is too wide. According to all the excel work I've been doing the V161 with a 4.77 rear would get us back into the powerband on many corners where we currently have to go as low as 4k rpm, and then keep us in that band better than stock during the upshifts. Anyone else tracking these cars heavily should also be interested.
Because of class limitations etc I can only run 340ish rwhp, so I have no need for a twin or triple plate clutch. Damian is at like 400ish, and his would be fine too.
Anyway, I'm just saying I'm sure there's more people who don't need the trans for the power, but could definitely use the closer gear ratios.
As carx7 mentioned, heck no. The T-56 has already been done. While there is obviously difference of opinion, I wouldn't recommend it (again carx7 has mentioned many of the reasons).
Also, lets not conclude about the trans pricing until we give it to you
What can I say man? You got me...lol 
Good point. I overlooked that. If necessary, sure, we'll provide a single plate as an option as well. Why not?
Oh and tell Damian that the kit won't be available until the undertray he's developing is available too hahahaha

I can come up with 2. My car and Damian's car.
