If parts were made available for sale, would there be any interest? i can make and supply 7075t6 billet flywheel adapter with ss2541 Splined adapter for DCT transmissions. Will bolt on to a miata 1.8 flywheel and mate to a DCT perfectly.
Engine mounts to raise the engine the correct amount could also be made, and probably the trans mount. custom driveshaft can be made but shipping would be expensive from norway.
A kmiata 6speed e46 bmw trans plate would have to be sourced in the US(no point in shipping it back and forth).
Im very interested in this! When do you think you can start making them?

There would likely be a market for this kind of product, but understand that it's niche product on top of a niche product, so the market would be somewhat limited. As a result, the pricing would need to be kind of high to make it worthwhile to produce and sell, which would further limit the market.
That being said, I think this would be BADASS to have on my Miata!

If parts were made available, you sir would truly be a scholar and a gentleman. I think this is tremendous and for those of us that are capable enough and resourceful this would be a great option to have available with your tried and true custom parts !
Would you be willing to measure the distance from the crank/input shaft centerline to the bottom of the pan? Would the m4 trans be drastically different than the 335 trans?
I've got bad thoughts of using one of these behind the LS in my Miata. Engine can't move though. Also the trans controller is a big stumbling block, not gonna spend $2k willingly on the ECM. Anyone been able to get the stock TCU to work? I can send some can data from the megasquirt but not sure it'll be enough for the TCU to function.
Or just tell me your ECM will cost less than $1k and I'll throw money at you.
Bronson. i can check that distance, i have a few of these transmissions now
BUT.. i needed to raise the stock miata engine 15mm to make the trans pan flush with the frame rails..
People have been using a few very expensive Syvecs ECU's and maxx ecu.. but even the highend driftworks buildt E30 with a V10 and DCT running syvecs are now so tired of not beeing able to get consistent results out of running the stock BMW TCU.. that they are also converting their trans to a standalone controller.. The bmw TCU combined with a aftermarket ECU controlling it, is just not a stable setup. it sometimes just does whatever it feels like.
I do not make the transmission controller in my car. mine is from the swedes behind DKGECU..
Thanks for the input, you were a little vague about which ECM you were running or I'm just bad at reading so thank you for sharing, I'll look into those guys and see what I'm up against. Those shift times are intoxicating.
not only the shift times are cool.. but we are running this trans with stock clutches on a 750whp ls turbo chevy nova on 335 wide r888 tires, and it holds up fine its a stronger transmission than any miata can ever need

Agreed on all accounts, I'm only making 400 whp or so. The gear splits are very nice too. Sucks not rowing your own gears but this could be worth quite a bit of time on the average road course
it feels kinda cool just staying in the throttle, feeling a endless push of power, no turbolag between gears. feels like my ducati panigale with a quickshifter and with the right diff ratio it will have a nice cruising speed, and tighter ratios than my 6 speed did

Hi!! Wanted to know if you could give or sell the CAD file of the splined adapter or just the spline im making a adapter for a diferent engine and you would save me a huge amount of time please pm me of you can help me out thanks!
I won't testify to it, but IIRC from when I had my 135, the trans is in the 175-180 lb area.
That seems crazy heavy. It doesn't look any larger than the ZF 6-speed we use, which only weighs 96 lbs. I'm sure it's heavier but I'd like to weigh one.

Trans weighed 80kg including 8?! Liters of oil.. Keep in mind that that also includes the clutches capable of handling 700ft/lb
But yeah its a heavy bastard. i weighed a 6 speed manual diesel trans at 55kg, and the miata 6 speed at 35kg. So it adds weight to the car, but it more than makes up for it with short gear ratios and fast shifting. And the weight is placed down low and in the middle of the car.
Well done Harold! While I appreciate your vision and resourcefulness in making at all work it’s the fabrication quality that’s got me the most impressed. I’ve spent a lot of time around fabricators over the years and while most “got the job done” there were a rare few that had the great vision to make it a work of art as well. I’d put you in the later bucket. Mad props!!!
It’s pretty funny to find thread this thread while searching for a way to fit a BMW Samsonas transmission to my Miata. While possible I just don’t have the skills or the appetite to pull it off like you did. If I had your skills I’d be putting the BMW engine in there too! Dry sump S65 4.4 stroker engine. 600hp 😳 It’s all from a BMW E36 track car I am looking to part out.

Thanks for the kind words
The samsonas box should be epic, just install a different bellhousing on it as the V8 bellhousing is quite big. if you can get a bellhousing for a e46 6slinder car it should bolt up fine

Hi Harold, I’m in the same boat as Bronson. I also have a V8 Miata with a T56 gearbox that I want to get rid of so badly I can’t stand it. Did you ever happen to get that measurement on the centerline to the bottom of the transmission so we can see if this would work in a V-8 swap Miata?
