kmiata doesn't want to say much but i think you should cause it will create some hype. and trust me i am hyped. I will make it my mission to build a k miata turbo the moment i hear more details on its finished process. . I think that would be a dream come true.

turbofan makes a good point which is why I'm definitely not putting my build on hold, just finishing it lol. a part of me wants to part out and start the k swap, but... who knows when it will really be done.

Oh come on, the people that get overhyped about stuff like that will already be overhyped about what he hinted at. That's just how it goes. Even when it's all worked out and awaiting mass implementation, and they announce it, there will be those that will be impatient asking for updates every week.

It's one thing to announce what you're working on, it's another to set a date, or a deadline/ETA of some sort. I see nothing wrong with the former, and lots of things that could potentially go wrong with the latter.

What happens if someone else beats you to the punch cause you waited too long? What happens if people take their build in a different direction cause they didn't think what you're working on is possible, and dismissed the idea altogether?

Even the example you posted with TSE: the kit was announced years before even loose components were ready to ship to the public, and even still there is no "kit" released. Andrew learned a lesson with that one, but ultimately it's still happening and his components are selling like hot cakes. We're all still really happy with what he's doing, and supporting his efforts to finally get the "kit" completed. Now his announcements are "we're working on/testing xxx" and when asked for an eta he simply refuses to commit to one. Which is smart, it keeps people in the know, keeps those that would be interested still interested, but no one can blame him for being "behind" because there's no ETA.

Anyway, sorry for off topic rant but I just don't agree with the whole "thank you for keeping things secret" comments. There's nothing wrong with announcing things as long as you do it correctly.

I watched it when the FRS/BRZ's were introduced and companies were introducing forced induction kits. If you want to see a bunch of angry natives, read the Innovate/Sprintex supercharger thread on FT86club. People were PISSED off cause they weren't releasing details, numbers, and pricing on the kit while it was still be tested.

I can see it, and have seen it going both ways, so no argument there. I think the MT community is a bit more mature and supportive of our vendors, but maybe I'm wrong. Who knows.

Look at the Jackson Racing brotrex fiasco. Look at the....tec9 wheels or whatever it was from 949. look at the xid....I mean techna ......but seriously, I was ready to buy a set of those.

But I aint mad. Emilio wasn't happy with the production units or whatever it was, and I support his decision to not just "go with it" and lower his standard. Most people reacted the same way.

I feel like the original spirit of this thread was to compare turbo Miata engines and NA K setups for less than ~$10K.

Throw that budget (and the OE transmission) out the window and the only conclusion you're going to come to is that a 20 year younger engine design is a whole lot better. No one is debating which is the better engine, just which one is better at a certain price point. Start turboing the K and you run into the same problem as the BP - Why not just step up to a better engine to start with, namely, an LS1.

Good point. If money is not part of the equation, I suppose just about every other modern engine will be better than the bp

KMiata

Thanks everyone, I appreciate the support and understanding that we are hesitant to release info prematurely.

I will say this: we know that the Miata drivetrain is the weak point for guys wanting boost. There is another drivetrain option in development right now that can handle huge power. It is at the top of the list for new product development. I will post more info once a few more things are sorted out.

Remember, a stock internal k20z1 engine is good for an easy 600+whp tuned on e85. Who am I to deny full K series potential to the Miata community?

I got a dollar on it being an s2k tranny. Don't they already make adapters for K engines?

KMiata

Nah, S2000 transmissions are too weak for what we're planning. However I'm not going to play the transmission guessing game. Info coming soon...

Colipto

Very nice.. would really love if you could give us an idea on the tranny LS? B series? GSR? or k tranny... I feel like it has to be one of those

Someone fix the title. it should include that either turbo BP or K should can cost up to and including 10k

The K is more N/A style fun. Immediate, crisp, throttle position x rpm = torque

Turbo is faster, plain and simple. For the same power output, say 220whp on pump gas a TSE 6258 kit on an OEM long block kept under 7000rpm will last hundreds of race hours. Throttle response is still great, but not that direct connection from commanded input to torque. It's more like TPS x rpm / time = torque.

Turbo BP is a well trodden path, simple. K swap, while simple on paper, there aren't that many actually running regularly yet. David might know but I'm guessing it's less than 30 or so up and running regularly.

You want the best high revving N/A power, K24 is the ticket. You want to go real fast for a big easy button push, TSE on a BP.

TSE on a BP is a different ball of wax than any of the other possible turbo options, and as I understood it from the OP, the question here is keep the turbo kit that he already has or go K swap - with the intention to start tracking more often. Unless that turbo kit is a TSE (it is not AFAIK), the K series will offer way better reliability than the turbo setup. More miles = more smiles. My vote would be for the K in that case. Although, I'm conflicted a bit because usually my answer is along the lines "whatever you got, stop worrying about the parts and get out to the track"...

Currently installed is a 2560 with ARTECH hotside. However , I have another ARTECH hotside and an EFR 6258. I started considering the K when I was thinking about the trouble to pull the engine and build new water and oil lines. along with the needed valve springs. The mounting costs are what made me think about selling all of my BP stuff and going K.

I think that saying it HAS to be a TSE EFR is a bit overstated. TSE makes an awesome product,,l I will not dispute that. Arts stuff is also very nice and I don't think it should be discounted at all.
