I think if you plan on tracking the car at all, Naturally aspirated is really the only option. The person at the track who has the most fun is always the guy who does the most laps, not the 400hp turbo car sitting in the pits fighting issues. Best of both worlds is a k24a2 swap.

Completely agree. However, if engine cooling (oil, water, inlet temp) is managed well then a turbo is not an issue. Also don’t run very high boost. Finally, run E85 or race gas mix at the track to manage detonation for heat control. A 2.5L is easier and has more headroom than a K24 for ease of install. People always add power without proper cooling leading to issues. In this vid he doesn’t look like he has hood louvers=poor cooling.

Obviously it's personal experience. My 256/229 190k+ Miata did perfectly fine with no issues with 3 years of track and DD abuse.... Now it's making 400 with a 2860 and it's still just as reliable but it took a few months to get it all together. For oil temps I stuffed a 19row with -10 lines in the bumper corner and ditched the oil balancer. I always show up to the track with a trailer just incase something happens though lol For seal leaks I ditched the PCV setup and have a dual -10 breather setup and it's stopped pushing oil past the seals. I tried like 6 different valves and all are shit imo.

expensive. Honestly, if anyone has a vvti engine. Just get a megasquirt tune for 91. 150WHP. Will only cost you like $1300 total. You can get a bit more if you tune for E85.

Just my $0.02: Everything you said is accurate. Getting into a turbo Miata can be a huge pain in the derrière. BUT if "you" are willing to endure the pain, you just might come out the other side with a different outlook on the entire process and possibly a re-evaluation of what's important to you. I've gone through just about every stage of Miata-dom; stock, M45 supercharged, FM kit, DIY aggregation and multiple rebuilds. Where I'm at now is "borderline race car" - and I'm not done yet. (Here comes the "re-evaluate" part) Once upon a time, I wanted a fun, cheap sports-car that I could drive around without having to think about it. Now, I've devolved(?) into a power-hungry, performance-at-all-costs maniac. My car is loud, uncomfortable, vibrates like a paint-shaker, occasionally leaks noxious fumes and is generally not ready for prime time - but I drive it every day (and wrench on it every weekend) and I wouldn't trade it for anything and I won't drive anything else. And when I break something in it and have to drive my wife's Lexus, something inside me dies a little. So what's the point? If you want to be a normal human being, DON'T turbo your Miata (don't modify it at all). You will regret it eventually because it will not be a reliable, comfortable, sensible vehicle. But if you - like me - want to challenge yourself and accept the consequences of your decisions, then...welcome to the club.

Sorry your weekend isn’t going as planned, Greg! I think you’re right, we’ll see what this winter brings once we think on it for a bit. Can’t wait to turn some laps with you guys next year on track though!

Part of a Miata’s charm is the lack of power, patting the center console and urging the car to go faster; “C’mon baby, let’s GO!” Motor swaps and turbos may be faster, but IMO, it’s missing the point of a Miata. A perfectly tuned 150 hp 1.8 is the sweet spot. You know this, you just lost your way. If you want more entertainment, use all-season tire. Now ITBs might be a fun challenge, but I’d personally put that time and money into track time. Great video!

I’m on my fourth MX-5, some taken to extreme states of tune, and I appreciate this guy’s honesty. The nicest setup I’ve driven that is both trackable and real-world drivable is a friend’s 2019 ND2 Club, stock powertrain, and the suspension upgraded with stiffer sway bars and a premium coil-over kit using Ohlins shocks. For back-road sport driving the car is incredibly responsive, and thanks to the upgraded 181 hp engine and close-ratio 6-speed, this car does not feel underpowered. (Car & Driver report 0-60 in 5.7, 1/4 mile in 14.4, 140 mph.) Body roll is pretty much eliminated yet the suspension remains very compliant and comfortable even on California’s trashed secondary roads. I wouldn’t change a thing.

Yo dude, our community at the Nürburgring has been telling exactly this to people wanting to Turbo their Miatas. I dont doubt that you can eventually make them reliable if you take care of all of these issues that keep springing at you out of nowhere, and by the time you are done you've spent so much that you should have considered other options. Also you don't want an issue to happen on lap 1 of a trackday that cost you half a grand. I've wasted my money on a couple of 1.6'es and just recently a 1.8 + cams + ITB + header etc, and its just too slow and underwhelming. My suspicion is this is partly due to the absolutely terrible and unfixable intake runner design in the head. Anyway, so the lesson is DO NOT WASTE YOUR MONEY on these engines and just straight up switch the platform. We have someone with an LFX swap and this car has ridiculous power while being super reliable, and another with a K-swap going on. My personal project has been a 13B swap in another miata chassis for a while because I built a tiny simple ITB 12a for my RX7 and it pulls so much harder than anything those BP's could ever dream of. There are many options out there.

A k24Z3 is making 209whp right out the gate with just the kpower kit and your 10k. Or stick with the BP, spend less, have more options for N/A bolt-on modifications, and in the case of Quinn at 192whp; get within a stones throw of what the K24 is making with arguably the same reliability.

@@NappMotorsports Luckily there has been some awesome discoveries and advancements in N/A building for these engines in the last few years, a big part in favor to Quinn. 170whp and 180whp on stock bottom ends are becoming normal and are essential repeatable formulas anyone can follow. I for see a boom in the next few years as I've noticed a big uptick in interest for ITB miatas. I will not be surprised to see 200whp N/A builds becoming much more common as the aftermarket starts developing more N/A specific parts for these cars. I'm really wishing for someone to develop an aftermarket head with similar or more flow than a K series. That will make the K and other motor swaps obsolete if this engine with upgraded head could produce upwards of 250whp. Think of it from a cost perspective as well. I doubt a aftermarket head would cost half of what it cost to swap a different motor into the car and the install would be light years more simple. If you're interested in an awesome build for proof please look up a user called "Thomas Gee" on mx5nuts as well as the MX5 ITB face book group. He's an average joe who spent honestly an abnormal amount of his personal time researching BP head flow design and has built his own flow bench to test his theory's. All his hard work paid off as just yesterday he posted the dyno figures to his current build (ITB full build) and it was impressing. 267hp and 200+ lbs at the flywheel achieved below 8k rpm. Very detailed documentation over on mx5nuts. I think it was called sr2 roadrunner build or something like that.

Car was drinking coolant, white smoke out the tailpipe, so I took the head off and had roughly $1200 parts on order to fix it and rebuild the head. Turns out some of the intake manifold hardware had backed out, specifically cyl 1 & 2, causing coolant to leak out of that jacket and into the ports in the head, had nothing to do with the head gasket.

See this is the value of an n/a setup. That’s fantastic and sounds like such a fun time.

This is what most people don't talk about online, yes you can make a bunch of power on a budget by turbocharging the factory engine but it will never be as reliable as staying N/A or swapping in a more powerful engine like a K series. I was torn between a turbo or K swap for my car (not that I can afford to or have the skills to do either) but after hearing so much about the reliability of an N/A K series it seems like the best option for me if I do go down the road of more power since I want to be able to beat on my car on the track without worrying if my setup can take it or not. It's the old saying that a car can be reliable, fast and cheap but you can only pick two of them. Want a reliable and fast car? It won't be cheap. Want a cheap and fast car? It won't be reliable. For a 100% street car I would still go with a turbo for the low end power over an N/A K series since it's not being pushed that hard

Yeah. I think this is exactly what Stefan and I learned this year.

On my first turbo, a 1.6L with gt2554, I did a 6 puck also, which I also completely regreted ... Later on a 1.8 turbo build (gt2860 that time), I used an ACT pressure plate with an organic disc. It was the perfect setup, great drivability, never slipped. However, I did regret getting the bigger turbo. Sure, it made more power, but was too peaky for me. I preferred the fast spool, lower threshold of the 2554 and would even consider going even smaller if I did it again ... But, I really dont think I will. In the end, after those two, I got an NB99 and left the motor stock. I actually enjoyed it every bit as much, if not more. Its just different. I've been miata-less for 5 years now, but finally looking at getting another soon. It will almost certainly be naturally aspirated, with a focus on handling. If anything, I would consider higher compression and some bolt-ons.

@@NappMotorsports Vacuum is the biggest issue, or lack there of. Also the tuning window from Zero throttle to Full is very narrow because of the amount of air they let in at part throttle, this means the resolution is less than a typical NA tune, effectively you have fewer zones to work with. Elevation can be a factor and gas mileage is also quite poor. From a street car perspective the car is significantly more compromised than stock or a typical boosted setup. On track they do work well but not significantly better than a single throttle car. They do sound cool and make some power, obviously responsive and part throttle power is improved... because it's closer to full throttle due to airflow.

From what I've heard, the transmissions are quite durable out. Of course, you can do a lot of work or replacement. When you do an engine swap and 3 liters, 6 cylinders seem to be a really good way to get an NA engine that works. More talk more horsepower and some examples add little to no weight. But of course, as we know now, with proper suspension and break upgrades, it's not a real issue. Some people go crazy with weight distribution and even start to put lead Is fishing weights in the bumpers for corner balancing, etc.

Sucks that you are facing all those issue with the car. I would suggest swapping the clutch for sure. N/A or Rotrex if you want reliability from a track car. I remember doing a ton of research on the subject while my NB still sits in the garage. The amount of issues turbos have if not done correct was not worth the hassle. I have read everything from warped manifolds, leaking seals, leaking exhaust, lose bolts, spool issues, waste gate issues, bearings..... People complain that Rotrex doesn't make turbo power but Rotrex also won't make turbo issues so there's that. My advice would be to tear the engine down, maybe blue print the engine because it might have internal issues you didn't notice.

Nice. Good things to think about.

Dylan, it's a shame that you feel that your set up is not providing you confidence in the car but 250hp turbo set ups can be reliable. Perhaps the engine is not in the best condition or has some hidden niggles and this leads to a whole host of issues that just make you feel negative about the driving experience. (Yes, a pucked clutch is not really streetable with 250hp. I run a full face sprung organic clutch with similar power levels to you and its feels like OEM). ITB's would be a good project but I think that now you have experienced 250+hp and loads of torque the peaky ITB output will not bring you the satisfaction you crave. This winter is a great opportunity to consider your options and give your turbo set up a few tweaks to get it reliable. I run a journal bearing TD04 on a 1991 stock 1.6 with 12psi, oil cooler, coolant reroute, ali radiator and have zero heat issues with coolant or oil (5W-50 Castrol) on track or on the street and no turbo lag (I don't even have vents in the hood/bonnet!). So there's no reason why you can't achieve the same reliability and drivability with your car. I would suggest: 1. Definitely swap out the clutch for an organic full face unit (as it is so integral to an enjoyable driving experience). 2. Swap in a non-leaky stock engine with good compression test results (as yours seems to have gremlins). 3. Keep the GT2560R (unless yours is a dud), as it is known to be a great unit, and do a refurb' on it to make sure all is OK internally. Perhaps even take the oil feed from somewhere else? 4. Run a better PVC set up to ensure minimum crankcase pressure - I run both outlets on the cam cover to a catch can and vent to atmostphere, with the PCV inlet port on the cam cover capped off. I get a few teaspoons of blow by in the can after a track day. OK, the engine swap seems like overkill (and is the most expensive and time consuming option) but it will remove all the doubts you have about it and give you chance to swap in a full face sprung clutch. The other items are easily sorted. Love the videos btw. Keep them coming....

I have a 230whp turbo ‘96. It’s fast. Just not fun anymore as I’m always worried something is going to go wrong. If I were doing it again, I’d NA K-swap.

Yup. It’s a pain. I’ve never stalled a car so much.

to the people wanting to supercharge your miata, I can tell you from experience that it will have much of the same exact problems as a turbo build. I keep having non stop oil leaks and having to run the car on 93 right now is burning a hole in my pocket just to drive it around town.

Thanks for your feedback. What supercharger are you running? Have you changed anything about your PCV system?

Sell me the turbo kit. 250 whp is the limit of the 5 speed. Pcv should actually just vent to atmosphere in your setup. Rods and Pistons are cheap insurance and with a six speed trans you can push pass 300 whp. Greg Peters 400 whp is easy to replicate your halfway there. Also coolant reroute if you pull the motor. Good luck don't let this stuff get best out of you.

Thanks! I might end up selling the turbo setup. Going to have a long think about it.

My stock 90 NA 1.6 gets 32 mpg and that’s cool to me. It’s also dependable as a commuter. I don’t have an option here for track, but I could trailer on the weekends. That seems like a bad financial decision, all be it fun. Anyway, I’ll drive this little car until it sells and then buy a minty 2021 or older WRX STI...maybe a type RA. Likely not because it seems like another bad financial decision with its rarity and I want to daily it. Anyway, I’m 45 years old and have several cars, if I decided to make this Miata my project and enjoy the process with my 16 and 17 year old children, money well spent. However, they have a WRX and a BRZ. I have a tuned Ascent. So, 🤷🏻‍♂️🤔🧐🤣🤣😎 To each his own...Subaru!!

The big issue here is 3 hour track days. For a track car doing that much racing in one day a turbo setup is not the way to go. Powerband is not linear enough and heat management is a big issue. For a track car an NA engine is what you need. To me a perfect track car is an NA Miata. I feel bang for buck an LS swapped Miata is the way to go. 400whp NA and total reliability and TQ that makes shifting and all of that way less of a hassle. You can leave the car a gear high and have plenty of power for most tracks. For a street car where you're smacking it on the street and having fun a turbo BP is a ton of fun. I think a K swap is cool but I think the cost/benefit ratio is a little lacking compared to LS swap IMHO. I think Supercharger kits are best for the less mechanical owners who just want a little more power with a "set it and forget it" mindset. Not the fastest but makes the car much more enjoyable to putt around. On track or wound out the superchargers have reliability issues.

There’s a reason we’re going back to NA. I don’t think LS is the answer though, because the consumables are so high.

Just bought a turbo Miata project. After discovering some issues with the turbo kit I ultimately decided to ditch the whole turbo idea and go ITBs. So yes please do some ITB content! I think turbos are cool if you wanna just talk about HP or have a specific reason you need a certain amount of HP. Otherwise NA all day! Or supercharger actually.

Not a bad thing, just be ready to work out some kinks.

I spent 9.2K on my total NB which is in excellent condition with 55K miles. Don't think I would spend another 7K+ on a turbo that may actually decrease it's value.
