I’m in to see this comparison.
... vs. Ecotec.

Duratec. Doable with factory drivetrain parts (NC smoothcase 5 speed) so no PPF or driveshaft hackery required.
Supposedly the 2.0 direct injected head from a Focus, with a 2.5 block and 2.3 crank, makes for a righteously capable 2.4l engine.

Kit alone is less than a quarter the price of a K swap kit.
In fact, a turn key Eco swap is significantly cheaper than just the K swap kit
I'd love to see that.
So Ecotec miata already has the kit for the l61 and LE5 which you can easily get 200whp out of the LE5 however, they are now extending their kit to also allow you to bolt up the AR-5 transmission from the solstice/sky which bolts right up to the ecotec engines solving one of the other expensive issues to handle when it comes to building a high power miata.
Greg over at the Car Passion Channel did a great video recently on the transmission options, he also only included swap kit price not the trans price because everyone has different sourcing

The thing I haven't seen anyone do but is what I think I want to do is the ecotec kit should also work with the LNF motor and mate to the AR-5 transmission, now the LNF motor is only a 2.0 vs the LE5 2.5 but this is the factory turbo motor from the cobalt SS etc or the solstice GXP which has forged rods and can do over 300-350hp on the stock factory turbo and just a turbo swap can put it over 400
There's also a kit in the works to put the Ford/Jaguar AJ/Duratec V6 into the Miata. Not entirely sure why, as the J-series makes the same power, is easier to find and actually has an aftermarket. But it's coming.

I have the Rotrex-blown BP Miata
Ready, set...GO!
Am I odd for thinking a Toyota 1UZ V8 seems like a more appropriate swap into an MX-5 vs. an LS or Windsor V8's?

Ok a bit of a thread jack. But I would be more interested to see this combo in one of the dirt cheap RX8s all over Craigslist.

Yes. But it's okay. We're all a little odd here.
I guess it's like Cobra's and 289 FIA vs 427 S/C. Both have positives and negatives.

I looked into it... it's not that simple, because while some RX-8 and NC 6 speed transmissions are similar, everything about them is different. Everything in the RX-8 trans is bigger including the output shaft, according to my contact.
Additionally, the 5 speed in the RX-8 overseas is based on the ribcase trans, not the smoothcase like the NC 5 speed.

Isn't it one of those physically-pretty-big-because-cams-on-top-of-heads engines?

It’s been done, and for cheap.

Pushrod engines do have the advantage when it comes to size.

Oh sure, but when you make up for the DOHC V8's lack of density by repackaging things in otherwise wasted space, , like putting the timing chains in the bellhousing or the starter in the intake manifold valley, people complain about "those dumb engineers made it hard to work on"...
A rocker style OHC setup is the most compact, but there's no compact way to add hydraulic lash adjustment. And a lot of the bulk simply comes from having some of the valves inclined away from the bore centerline. Make an inline valve OHC head and there's really not much benefit over pushrods anymore.
So, before this becomes a "LS is better than all these swaps because blah blah blah" thread.
I want to know why the k-series swaps are so much more expensive than the ecotecs and other 4 cyl engines?
Also, what are the advantages of the J-series over the LFX?
Engine to engine I don't know the J series is, its just cheaper but also a less robust kit of offerings. The LFX kit has all new subframes, trans swap options, diff swap options, axles etc
In reply to pres589 :
I think the big reason for most of the swaps is more to do with transmissions than the actual physical lump of a motor. Is there a cheap and readily available manual gearbox available to mate to that nifty 1UZ engine?
Fords bolt up to T-5s because they were designed to do so. Chevies are there with their T-56. Both of these are available all day long on CL, what does Toyota have and is it more available than unicorn tears?
In reply to KyAllroad (Jeremy) :
Nothing bolts up to it without an adapter.
In reply to yupididit :
J-series seem to be much more common and, as a result, cheaper. The LFX is a relative newcomer. Meanwhile, Honda has been cranking out J-series in a number of vehicles for a over a decade. The J-swap also reuses more stock components, keeping the kit cheaper. The LFX is also a real pain to work on, although I have no experience working on Js
