I knew of these tranny and their strength, I never even considered these trannies because I'm used to foreign parts costing an arm and a leg at the pick a part. Like if you asked me cold how much an E46 tranny was at the pull-a-part I'd guess like $1200 minimum, probably 2k+ for one thats not totally clapped out, and thats close to custom gearset money, so no further thought went towards it.

Who would have though a new company would be able to kick so much *** in the miata modification market in such a short time.
Damn. Nice work guys. I am super stoked to be placing some orders with you in the future.
Edit: A small suggestion for the gearing calc - make it so you can view the results of two ratio presets side by side with all other settings the same (redline/tire size). This was you don't need to have two windows side by side to quickly see which trans you would want in your car.

This trans setup will be fun, I think it checks many of the right boxes for guys needing a stronger trans option.
7.5 lb, paired with a 13.5 lb flywheel.

That's very cool and definitely something to think about.
Out of idle curiosity (I like a real manual, and even if I didn't I hear they're not not all that reliable), does the E46 SMG fit?

Great transmission choice. These transmissions are really cheap in Europe, you can pick up a 5 speed from around 100 euros and a 6 speed from around 250 euros.
The GS6-53DZ (diesel ratios) is really plentiful/cheap here and is rated for ~500Nm / 400 ft/lb. Not entirely sure whether the diesel box fits in the same place as the petrol one, I thought the bellhousing was slightly rotated compared to the petrol one. Also the ratios are worse. But I guess the diesel boxes are not present in North America.
These boxes are almost the default choice in the European drift scene right now. You can get almost any adapter plates for these here: Toyota UZ, Toyota JZ, Nissan SR, BMW M60 / M62 / S62, Mitsubishi 4G63.
Still I am wondering what the final cost would be for a BP engine with Mazda diff. The amount of parts needed is quite a lot. With a boosted K and the Getrag diff I think it makes an awesome package though and almost a no-brainer.
Maybe this kit enables me to build a very cheap K powered E87 1 series (because those cars are massively plentiful and cheap here)

Sorry for the shameless plug, but this is super exciting, and it makes me miss my old e30. I had used the MZ3 shifter, it's taller but the pivot arm is a bit longer reducing throw. This is making me nostalgic for my s50 e30 days where I fashioned a plate with the UUC ERK:
So the carrier i was using for the shifter was just too short and fell out of the rear mount. Mount went missing. So....driving with the selector rods bouncing on the driveshaft was no fun. This is my budget 'dtm-style' shifter which you can make fun of all day, but it lets me shift without saying hello to my driveshaft.
I disassembled everything and punched out some of the perforated sheet metal. Drilled one hole where the interior mounting stub used to be.
I cut a piece of aluminum to roughly fit and chopped up a spare carrier i had laying around. Tom@WickedInnovation was able to weld it to the plate after a hole saw was used allowing the shifter to pass through.
The shifter I was trying to run initially; MZ3 that used to hit the driveshaft in normal configuration. Shown also is the UUC Effort Reduction Kit (ERK) which also positions the pivot a little higher.
The white and black bushings needed to be slotted to fit the shifter. Here is the white bushing installed
The UUC ERK shifter cup
UUC supplied some loctite (they are also very thorough and friendly folks)
aaand.....
The black bushing installed on the shifter (it wont fit over the body of the shifter hence a slit to be cut for install just above the pivot). The spring and retainer fits perfectly without mod.

just not letting you use this as a crutch for an excuse. You're so close to the finish line.

GPS based speed adapter?
On one hand, that's incredibly cool and means that you should theoretically have more accurate speedometer readouts, but I do kinda worry about not having a direct mechanical or electrical input from the transmission. What happens when you go through tunnels? (about .00001 of my driving time). How fast does it respond to changes in speed? Much slower than a direct wired connection I am sure.
I hope they can find a way to give options on that.
