K-Swapping a NC Mazda Miata in 48HRS!

If we don't get this swap done in time, we'll lose the shop! Ok, that's a lie, but thanks to David and Lew from KPower Industries we were able to complete this Honda JDM K24 engine swap in record time using their incredibly well designed, brand-new-to-the-market Mazda 2006 - 2015 NC Miata MX-5 K swap kit.

[@LuxKeiwoker]

Catless? Common guys you can do better than this

[@mikee8723]

$10,800 for the kit if you want to retain AC. NOT including the price of a K24 that is 205hp. I'll take a Duratec 2.5 swap with 175 and 174 trq. For at least 1/8 the price. If you wanna get wild, cam it, tune it and turbo it and it will make more HP and if you blow the engine go get another one out of a Fusion for 400$. I love the K-Series and this ultimately has a higher power potential, but seat time and consumables costs money.

[@sjhudon386]

This engine is 220whp and 200wtq at minimum.

[@mikee8723]

Fab9 tuning makes a turbo kit for $5700 which makes 275-450 wheel HP. Yes, you can make more than that with a Turbo K-series. But, nobody in their right mind is gonna rip on a 2400lb car with over 450hp. Plus, your going to run into issues with the stock trans and Diff at that point. Like I said, the K-Series is a better engine, but the price of consumables and other supporting mods could be upgraded for the price difference.

I bet it feels good to do pulls in a k without torque steer!

[@michaeldavidblunt]

Such a beautiful build! This is the sort of engine the NC deserved from the start. OEM engine is so lethargic and the car feels bloated compared to the NA/NB generations. The added power and torque would make this an absolute blast to drive! Just curious, being the car was completely gone through and rebuilt, was the chassis stitch welded or any added bracing installed? I also noticed how hard the shifter turret flexed on wot pulls. Will you guys be adding any stiffer bushings in the rear to hopefully tighten it up?

[@hyper8545]

Always wondered why we don't see more of these swaps

[@mikeb1039]

In 1993 we bought a year old Accord. Great car. Drove it 150,000 trouble free miles. In 1998 I bought a 95 Miata. Said many times "that accord engine would be amazing in a Miata". (and that was with a LOT less HP than the more modern versions). Back then the FWD to RWD was a stopper. What's changed with that to let you use either?

[@ethereous]

Great video, great guys, and the products from KPower seem great. But my god, this is just a perfect example of more money than sense. This is a 15-20k swap for around 80HP. Jesus man, that's V8 swap money or a whole extra Miata. I just don't get this other than internet/Instragram brownie points or an obsessive love of both the K Engine and this particular chassis. An S2000 seems like a significantly better buy.

[@Sharpened_Spoon]

Enjoyed watching this process. As far as I understand, and I’m no engineer, I think that Helmholtz resonator tube before the muffler is supposed to be as close to the headers as possible, otherwise the resonant frequency still exists in the exhaust pipe all the way up to the point it meets the resonator. So it’s potentially doing very little. You can package it further up using a wide chamber connected to the exhaust pipe with a narrower pipe. Maybe no other packaging is possible but it does sound like it could be annoying as an OEM+ option. For track I guess it’s whatever.

[@BLKMGK4]

So, what are the turbocharger possibilities in this chassis? 😈 I've heard of it being done but how much pain is it? A turbo K seems like it might be a REALLY nice combo for this chassis :) Nice Helmholtz chambered exhaust BTW, that will make a massive difference if it's been tuned correctly - speaking from experience!

[@beansandsausages]

Beautiful build right there - Kpowered miata must be such a fun drive! Looks like such a pleasure doing this swap with the Kpowered kit they've thought of everything it's like building a lego kit with the guide. I would love to do this with these guys' kit. Shoutout to SA as well for continually bringing excellent content and always trying to think of new ways to change it up and explore new formats for thier videos. Love you guys and wish you had the recognition you deserve - should be a 1+m subscriber channel for sure!

[@EchoSigma6]

16 hours for this is possible with two experienced techs using a lift. An average backyard mechanic is probably looking at 3-4 weekends with a buddy to help not including the AC recharge and alignment. However, your mileage may differ depending on your own conditions. I want to see a cam’d 2.5 retrofit. I’m sure the K24 is superior but the 2.5 is more financially approachable.

[@barryeverson9320]

My question is . Besides labor cost ... what did this entire build cost including the car ? This is basically EXACTLY WHAT I WANT !! So I am Interested in knowing how much it's gonna cost me lol

[@aroundomaha]

Thank you for an inspiring build. An NC build is now on my bucket list!

[@pattyboi]

Seems like such a good kit and chassis, my god

[@dlg5485]

I recently purchased a ND3 GT 6-spd manual and I love it, but I plan to keep it pretty much stock, except maybe a Goodwin exhaust and some upgraded anti sway bars. I'd love to build an NC like this one someday, so I can preserve my ND3 for the street and also have a built NC for racing.

[@thewatcher2.070]

so i got a question, if i understands correct there is a smaller crank pulley put on this motod to "under drive the acaccessoires". Does that mean the moter has to draw LESS power to drive the AC? Idk just came on my mind.... Thx for answering if its getting answered!

[@zmarko]

Is Pete ok?

[@markwalton8644]

I'm not sure why the Swap? The 2.0 motor will happily do 225 bhp with cam mods. With Headwork 250bhp. Plus the Mazda motor is all alloy so is pretty light.

[@jasonyoung6420]

19:50-19:59 well that line is 100% BS; the real reason steel was used is because it's significantly cheaper (aka more profitable) than aluminum; worth noting that both the block & transmission case are aluminum, good luck on your first clutch job, separating dissimilar metals is fun.

[@kunzesaur]

Imagine doing all that work and not replacing the old power steering fluid reservoir lol Seriously though, awesome swap. I wish I had an extra $10-15K lying around.

I'm fairly certain the only individuals who are going to see the value in this swap over the duratec swap are using it for competitive racing applications. The k swap is faster but a much much much much more expensive swap. The value isn't there.

[@gorillagrips27]

Weird. I talked to k power 2 days prior to this video and the release of this and they said you don’t need the v8 roadster subframe. But now I’m just wondering if it’s worth the extra money for the full kit

[@bohemianraceart]

Only thing its missing is a nice beefy wheel setup like regamasters 17s maybe a mini tube to get a 17x10 in the rear. This thing would look 🔥🔥

[@rvarsigfusson6163]

What about to swap it into the RX7 or special RX8, is that possible. What about the turbo or blower to Mazda engine? What about the price of it ALL?

[@jaysmith2385]

So a few questions I had was that a person trying to keep the costs down, could you cut the oem subframe and notch it to make the motor fit? Additionally, when installing the clutch do you need a pilot bearing like most k series clutch kits? Or is that not needed?

[@ncole0706]

Meanwhile nc Miata guys that have done a 2.5 swap have all done the subframe dropout in their home garage including myself without a lift.
