I can attest to it costing quite a bit more than most people imagine. I bought the top line kit but of course the cost of the engine, I did pay for my install which included repeated times of parts not fitting (oil pan), having to send pieces back or replace with something else, and tweaks to the car in general. This is more than a swap, it changes the entire car. That said I’m thrilled but it took a year of testing it out (track car only) and making adjustments, tuning etc, to finally get it settled. It is not for someone on a budget and sometimes buying an already set up K swapped Miata would be less expensive. That said I have no regrets and am now happy.
This is my dream swap. I did want a 1UZ swap for that sexy V8 sound, but the cost would be insane. Someday I'm going to do this. Thanks so much for the list. Seriously.
Excellent breakdown on costs. My costs for the items listed were close to your with almost all Honda OEM parts. I purchased one of the early K24Z kits and chose to piece together parts due to the route I went (S2000 transmission and in an Exocet). Overall a good experience but I ran into issues with incorrect/missing instructions and the oil baffle hitting the crank. Seems those issues have been resolved by parts updates and revised instructions.
Thanks for your comment. That sounds like an awesome build. We had minimal issues, but did have one thing mislabeled in the wiring harness. Other than that it was smooth sailing
@@Pagelos I have my Miata since March, so I didn't had even that chance, but I've heard of 500€ miatas selling there... Will try to be sure and if yes I'll go there to pick two or three!
I'm 50 years old And ive seen engine swaps done by people And a lot of them wished they'd spent 5 grand on what they had !!! As the worked out they'd have less headaches less expenditure and less brain tumours from the stress 😩 My advice update original engine brace them lighten and strengthen the reciprocating parts turbo them e85 them nitrous them if you're crazy keen Had a mate put a v8 where a 6 was 5 grand 20 years ago Said he wished he'd spent that on the 6 My 2 cents worth Jmo
I’d counter that. I supercharged and built my ‘02 and ran it for years. Or let’s say tried to. With low valve clearance that engine is not designed to be revved like that and it kept breaking, one thing after another, particularly the at least three valve jobs I had and more. loved the beast and driving her but after too many huge costs over and over I finally went to the K swap for speed but reliability. The more complicated you make the car the more things can happen. Your experience may vary with a turbo if you don’t build the engine.
Really appreciate this video, been thinking of going kswap in my 91 NA Miata and now that I got a guide on how to most definitely will be doing this soon. Also the kmiata kit comes with a subframe ( I believe ) and that's so you don't have to cut out your hood or get a custom valve cover, what convinced you guys to go with kpower ?
KMiata became KPowerIndustries! The custom sub frame is for the A2 swap and isn't needed for the Z3. Matt picked this swap for cost purposes believe it or not, over the A2!
I would just keep the stock block and add a supercharger. The stock ECU and fuel system is already to go for boost from factory on the NB. Good video but this is way too much money to get not that much.
You need to trick the ECU with a way to retard timing and add more fuel. Also it is really easy to overwhelm to OEM cooling system with boost. But you are mostly correct, the injectors are good to the limit of the stock bottom end.
EVERYTHING custom costs a lot more than you think! Add another 2k? for installation if you can't do it yourself. I'd be ok with the $, but then you've still got the constant concern of if it was done right and not going to fail you down the road. Read about an awful lot of those!
a good k series engine properly cooled with proper maintanance should be bulletproof if you dont go overboard in the hp department and keep it relativly stock and honda 6 speed box is pretty much bomb proof at those level of torque levels so really your only concern should be the instalation process and the wiring process if those are done right this mx5 na with k series motor should be just as reliable as your typcial honda civic in fact it might even me more so due to less stress on the box and motor due to the feather weight nature of the na mx5.
It’s been a long and expensive process but my 91” NA has an Sr20det which has been rebuilt with forged internals. I didn’t go cheap. I have an aftermarket ECU as well. It cost over $10k for the build.
If I remember right Matt went for 7800 RPM, but it can likely have gone higher, we went with that for safety. I believe we show it in the Dyno video we did!
It does not but that’s not the idea of the build. High revs and a reliable stock engine is the name of the game with these. I can assure you Greg’s car costs a lot more than this to build. He needed a full driveline upgrade, a expensive turbo, manifold and downpipe, and tons of custom work on a built engine. That’s not cheap and it also hasn’t been the most reliable for him unfortunately. Insane car and great channel though!
It's worth if if you want a quick reliable weekend car or dedicated track car. Forced induction setups aren't that much cheaper and are definitely not as reliable.
4300 for the swap kit? I want whatever they're smoking. That kind of money could get you an awd swap kit for a civic. How about those coke heads stop charging an arm and leg for an transmission adapter plate and engine mounts.
@@xxxdemonitation9538 I am from Europe - Latvia , I have mx-5 but only because it is cheap car with RWD [winterbeater]. for us there is no go to put in money in this car, because for 7,5K we can buy porsche boxter with 2.7L engine and get instant fun of power.
Hello? 2022 called. You can't buy any decent used sports car for less than $20,000. I'm looking at this swap because the Honda S2000 has doubled in used value over the last 2 years!

Nice build, great description of the swap and all that goes into it.
Thank you, and thanks for watching!

Appreciate this a lot. I am thinking of k swapping mine, but living in Sweden means 30% import duty + freight. FML
I know the feeling... I live in Portugal, want to turbo mine and have the same issues...
@@goncalorosa5963 At least before, many parts could be bought from the UK. But then Brexit happened! 😭

Just turboing the stock motor seems like the best bang for buck.
After 3 years with my 1.6 turbo'd, I agree :)
I’ve been reading the engine doesn’t like to be supercharged and a lot of them don’t last 5 years like that

to do it right costs almost the same
@Christian-nl4cl not at all. You can easily make 220-240 (the same range as a k swap) with a turbo on a stock engine for like 7-8k
You guys are awesome for putting this video together!

Thank you for sharing this, very useful information!
i knew right away this was going to be in the 5 figures range. at 0:36 if thats not a big hint i dont know what is. LOLLLLLLL
i picked up 90 miata glad you got videos on alot of the work it needs. thank you
10k-13k is a steal for a miata with a nice motor
Nice to see pricing, awesome swap but I think after watching this I'm gonna go the supercharged 1.8 route.
I think you’ll have plenty of fun that route as well!
K swap is the way 🚀🚀
Will the ac work?
The link for the oil pump adaptor kit in the file doesnt work is it the same as "K20 Oil Pump Upgrade for K24Z3"?
Thanks for sharing, is the part list same with K20?
Can you post the parts list and cost or a pdf called K24 Swap
this kid matt actually the cat
I cannot believe you just revealed that to the world

how reliable is the 6 speed mazda Miata/rx8 transmission with the K swap?
EVERYTHING custom costs a lot more than you think! Add another 2k? for installation if you can't do it yourself.
I'd be ok with the $, but then you've still got the constant concern of if it was done right and not going to fail you down the road.

How did you get the hood to close? I just finished mine and cannot get the hood to latch even after cutting out pieces
Did you buy the modified valve cover with your swap kit?
@@CashedOutCars yes
Might as well get an S2k
I’ve seen a few of these K swapped Miata’s rev to 8200 rpm, I’m assuming they were all the k24a2’s. How high were you able to rev the z3, safely lol.
If I remember right Matt went for 7800 RPM, but it can likely have gone higher, we went with that for safety. I believe we show it in the Dyno video we did!
My K242a revs to about 8K so far
I have My 96 Miata and a K-24 but no kit and no experience in installing the 2 together 😢 someone! Please help me.
👍
I have a welded diff is that aight lmao
I have an automatic Rihanna NC. Question is, does it matter with these swaps whether you're putting it into a automatic or manual?
much much easier to swap in a manual while youre in there anyway
Would the kit work with a k20z3
I'd recommend asking K Power direct to be sure!
Does it make 500rear wheel hrsprs
Greg's does for less probably

not to mention all the tools you had to buy...Easily 300+
Definitely, it tools quite a bit of stuff to get it done
I'll never understand swapping engines with the same number of cylinders.
Yapping🗣️🗣️🗣️
@@LINGLING1080P the irony
The motor is cheap, the swap is expensive. Not worth the 10k+ for just a 90-110 HP gain.
That's how most engine swaps go unfortunately. For the most part, I agree
Worth it if your planning to turbo it tho
It's worth if if you want a quick reliable weekend car or dedicated track car. Forced induction setups aren't that much cheaper and are definitely not as reliable.
@@RPG-oh1yf just get a faster car. When u start modding car the reliability start to go down.
It’s worth it as future proofing the car. Miata engines are climbing in price fast.

Do you get away with this swop on the rode?
ok I'll go buy a s2000😂
Buy me one too ;)
cadence
How did you end up fixing the oil pan leak?
It wasn't the ideal way to do it.. but we dried the area really well, degreased it, and filled the suspected leak area with more RTV. So far, so good
@@CashedOutCars good to know, I'm very scared mine will suffer the same fate. haven't started it yet
Just open with $12k Jesus.
Turbo is better 🤓 the K is to pricey 😂
Why not both ;)
@@danielskrskr price tag
Facts I’m gonna turbo first and if I ever want to push a little more then I’ll do the l swap
Reliability is the reason to K-swap. Those K motors will go 400,000 miles with little issues.
U can make easy 1000+ with k series, unlike Mazda engines.
K24 easy handle 400hp,when Mazda engine need everything forged.
but wait ! for 10K $ what car You can buy there that is stock and faster than MX-5? a cheap ferrari ? Porsche ? maybe other exotics?

Where you from bro?

About $10k? Not bad at all.
Not too bad for a lot of fun, expensive when compared the cost of the car itself
cheap AF I spent that much just on m suspension on my forester not including the coilovers
