My friend at the importer place said that there is 6spd trans. but he doesn't know if it's factory or custom. He's going to look and give me a call back......maybe it's a HKS or Greddy tranny
How cool would that be. We got a front clip of a Honda Civic last week that had full coil-over and Spoon everything (engine,ECU,CF hood,etc..) It is possible that the 6spd could be aftermarket.....I'll let you know.

Accelerating up to your top speed faster would be good. But with acceleration you lose a bit of top end speed. What Im looking for is something that will allow me to run through the first 4 gears fast so that I get up to speed fast but then have 5th and 6th a wider so that you can stretch out your RPM's and hit a higher top speed.
I had a look at a pic of a T-56 and it is a very large contraption. I doubt it would even fit into an RX-7 at all without having to make a new floor to compensate. Which is all fine and dandy for me 'cause I have to cut up the floor in the car that this tranny is going into anyways.
But, yeah changing the differential ratios would work too.
I dunno, keep thinkin of stuffs.
Anyone figured out what that 6-speed tranny for the 20B is yet?
Im out for a couple of days, so my R&D will continue upon my return. Friends 19th B-day taday!
Peace out!

What do you guys think makes tuning gear ratios so difficult and required with certain applications nevertheless? If you are gaining low end acceleration, then you are losing top end speed and that is that. It goes both ways. I have compressed 4:30 gears into a TII diff and installed it with a 5-speed TII tranny into my 91' NA. My low end is insane. My power band begins at about 2-3k RPM, so the 4:30 ring and pinion causes my car to idle higher and therefore start me right in my power band. The 18# flywheel is a great combination as I can rev it up into the powerband quicker as well. The flywheel sure took some getting used to though. You have to shift much quicker or your RPMs drop down too far. I didn't realize this before I bought it. I still like it though. Just gotta remember guys...if thinking about getting a lightened flywheel: the faster your engine revs (lighter the flywheel)=the faster the RPMs fall when you are shifting. So, the lighter you go, the faster you have to shift to keep your RPMs up in the same spot. I hope that makes sense

, so Ill just give yah the basics.I am making a racing car. Its being built for all applications basically. It will be able to do track, autoX, rally, and drag depending on how I feel that day. The car Im using weighs less than 1500lbs STOCK (no its not a civic) and I will be stripping everything out of it, making custom carbon fibre/ carbon kevlar panels, dash, intake, etc, so it will be far less than that when Im done with it. My car will be powered by an A-Spec 13T (ported) and I wouldnt mind using the transmission out of the TII, BUT the car that I am building is going to have a custom AWD system in it and the only transfer case that Mazda makes is the one out of the MPV (which Im not too fond on using), so Im leaning more towards the T-56 due to the fact that Ford and Chevy make more AWD cars than Mazda does. I would like even more to have a 6-speed transmission so that my car will be able to accelerate well and also be able to hit those high top speeds for the racing situations. The car I will be using will be old enough to bypass the local emissions laws, so it will have downpipe, midpipe, and straight pipe from there back. Seeing that everything is being swapped into this car from the TII, I will be upgrading almost everything imediently so I wont have to go back and upgrade later. Also a lot of things will have to be custom made (ie: intake, exhaust, hoses, etc.) to fit in the engine bay. Fully adjustable suspension (maybe the one out of the RX-7). Another thing is the front and rear wings, both will be fully adjustable either electronically or manually. The rear spoiler will sit flush on the back (so its not noticable) and can be raised up in order to create a down draft when required. The car will obviously be equipt with a full roll cage (6 or maybe 8 point), racing seats in the front (removed in the back) with 4 point belt system.
So even though the T-56 is heavier than the TII tranny, it probably wouldnt matter all that much, the amount of weight reduction that will take place will probably compensate for the weight difference.
Im not sure what else I could tell you with out revealing the car that Im using. I want to be the only one with a car such as this.
I hope I answered your question.

I am very happy right now.
I just got emailed by the guy at Grannys Speed Shop aboot an adaptor kit for the T-56 transmission, this is what he wrote
"The aftermarket version of the T-56 for Chevy applications uses the same bellhousing pattern and clutch style as the T-5 does, which would allow you to use the Kennedy T-5 adapter with that version of the T-56."
Which means that the kit for the T-5 transmission at the bottom of this page can be used for the T-56.
http://www.kennedyeng.com/other.htm
The price for a T-56, from what I can find, is ranging from $1600-$3000 depending on which one you get.
TTC Automotive carries 3 different ones, all with different gear ratios. http://www.ttcautomotive.com/products/tremec/t-56.htm There is no listed price however.
Could you guys check out the gear ratios on that site and let me know which one you think would best suit my application? A, B, or C? For reference to application please see above.
Thanks

I forgot to mention, the kit from Kennedy Engineering for the T-5 costs $300 and I think the kit # is 9900.
All prices above are listed in USD.
Another question. I dont know if any of you would know, but are you able to purchase transmissions from Key-Stone? Do they distribute transmissions, specifically T-56's? Im wondering because my brother and I are planning on setting up an account with them.
Thanks

spyfish, what kind of "sleek light" kit did u use on your yellow FD? Or is it a custom-fab set?
*on topic now* geez, that project seems crazy...
post about it when you finish
