We want to see the crate version of the 5.0-liter V8 from the Genesis R-Spec .

My thoughts exactly. There needs to be a Genesis Coupe 5.0 R-Spec!

I doubt the Hyundai motors are a direct bolt-in. Probably not as much work as an LSx swap but still not simple.

For the amount of money you'd spend on getting a Hyundai motor wedged in there, you could get quite the turbo setup. The Miata motors take to turbos very nicely.

For example: http://flyinmiata.com/turbos/index.p…

I want their i20 WRC engine! Yeah, I know it won't be offered. But one can dream.

Why? There are already hundreds of v8 options out there and with much more parts availability. Just snag a dirt cheap VH45DE, LSx, etc. If you are doing all the work of fabricating in the engine and transmission, who cares what the original output of the engine was... power mods are going to be much easier than the rest of that work.

Yes, there are a lot of V8 options but why not? As a biased owner of a 2013 Genesis Coupe 2.0T R-spec, I would love to hear the turbo of that engine in a Miata.

What... I don't... do you think... are you.... Yeah I have nothing. I can't follow your logic at all.

I know, I just made an illogical (or impractical) inference compared to all of the other cheaper and better options you can choose from for a historically respectable car as a Miata. But then again, I just disclosed I'm favorably biased toward the laughable and short history of Hyundai, so to each their own my fellow Opponaut.

Not as much work as an LSx swap? In what way? An LS swap might be the easiest swap on the planet.

So why not just get a 2.0 from a Mitsu Ralliart then? Nearly the same engine with better internals. http://www.4b11t.org/theta-ii/

I'm more confused why you think a Hyundai has a unique turbo sound. There have been engines around for 20 years with the same basic configurations (such as the SR20DET). I just haven't seen anything impressive out of Hyundai to see why I would choose one, even if available, over other options.... but if you want a Hyundai powered Miata, have a day.

I didn't say it was unique. I just said I liked it that's all. Soon I'll post a review of my car. Prepare your machete, because I think you're going to have the urge of tracking me down to kill me.

2.0T engine = Lan-Evo X engine except designed to be longitudinal RWD. Plenty of parts interchangeability in between them too. It's a good engine, so why not?

Because the Hyundai version of the 4B11T is actually designed to be mounted longitudinally in an RWD setup instead of horizontally in a FWD/AWD setup? It might not sound like that matters, but it does. Most important of all is the placement of the oil injectors which usually differs between two, and you risk oil starvation if you don't make sure it feeds properly under high G loads in your chosen setup. There's also the issue of transmission compatibility which can be pretty tricky.

Ah! Very interesting. I thought since the blocks were essentially the same design, they would be interchangeable.

Need more crate motors from different manufacturers.

It's not a matter of it not being a good engine... it's about it not being better than the other options. For the amount of fabrication work you better compare it to every other option possible. Simply being longitudinal means there will be parts differences between engines, let alone manufacturer preferences and packaging options for space requirements.

If you are going down all that work, is the engine good enough to rule out just doing an LSx swap (a lot cheaper), SR20DET (little cheaper, tons of parts), or boosting the original engine? My point is just that other than to say you used the engine, it doesn't seem to have any high points over already available and equal or better quality engines.

Why? Because choice. Also, swapping in a 2.0T engine with 275hp into a miata wouldn't require you to source a different transmission, differential, driveshaft, halfshafts, brakes, hubs, suspension... and fabrication required to fit it all. The original Miata drivetrain is plenty capable of withstanding up to 350hp I believe depending on what year you pick. (I believe early 5-speeds are only good to 250hp, but the newer 94-05 6-speeds are good to up to 350hp.).

All you'd need is an adapter plate, engine mounts, wiring harness and ECU (which I'm sure would be provided in the crate kit). We're talking apples and oranges here.

I understand the whole "choice" arguement, but I'm looking for a logical one. You are making some pretty serious assumptions there simply because it's a 2.0T engine. Do you know the output shaft sizes match? You know for a fact you can seat the engine at an angle to meet the current Miata power train requirements?

There are already tons of 2.0T engines available, and very few can just drop in as easily as you believe. Further, why would you believe an adapter plate and engine mounts would be included with a crate motor for a Miata? Just because the store is selling a crate engine doesn't mean it comes with swap components for another manufacturers car.

Sorry, I meant wiring harness and ECU would be included. And I don't know what you mean by ''at an angle''. The Miata's engine is positioned straight up

As is the Genesis coupe's...

If you were talking about the NC miata (which would arguably be easier since intake and exhaust are on the same sides as the Theta engine) then the adapter plate could be designed to bolt up to a straight up engine.

Granted, I don't know output shaft measurements on either engine. And I will give you that there's already a full conversion kit for the LS engines out there, but it isn't cheap. Again, any engine swap takes more work than simply slapping a turbo on the stock engine, but some folks want to get creative. Go try to ask why to folks who swap rotaries into miatas to see what kind of responses you get. This kit just gives them another choice, and that's always good.

LSx Miata involves a new engine, transmission, differential, mounting kits, and relocating things like radiators and washer bottles.

If there were a completely hypothetical way to adapt the Hyundai turbo motor to the Miata's transmission, then a hypothetical motor-only swap would be less work than a full driveline swap.

Hypothetically.

As far as I'm concerned, everything you've just described for the LSx will have to be done for the Hyundai motor/tranny as well, except for the fact that there currently exists an absolute bevvy of what are essentially bolt-in systems for LSx swaps.

The community that's developed around LS swaps means that even if you disregard the mounting of mechanicals (for which there are so many easy solutions out there), the process of getting it running, keeping it running, and integrating it with existing vehicle systems makes it so much easier than any other swap fathomable. Hell, for many cars it's an even easier swap than swapping in something from the original car's immediate automaker family.

Oh, I'm definitely not knocking the LS swap. The Hyundai thing would only be easier if someone went to the trouble of developing an easy, engine-not-driveline swap kit.

As it sits right now, there are readily available ways to get an LS motor into a Miata. There aren't any readily available ways to get a Hyundai motor in there.

Basically what I was getting at in my original post is that between bolting a turbo onto the Miata's motor, or doing an LS swap, there's not much room for a Hyundai motor swap option to make sense.

I'm not arguing against creativity. I'm just not seeing the logic. I guess I have just done too many unique swaps. Unique almost never means better, but almost always means more work and planning.
