Today, we are back with a build that wants to jump out of its skin and prove itself worthy every moment it's on the road. This E85-tuned 2001 Mazda NB Miata has been equipped with a Gen II Garrett GTX2860R turbocharger which is in constant disagreement with the rear tires. It's the kind of battle that separates the ordinary from the frightening. This turbo, in addition to the built 1.8L internals, allows it to make a ridiculous 470 WHP and 462 lb-ft of torque, but is it too much? Let's jump in this monster to see if an MX-5 chassis will survive the dance with this much boost.
Enjoy!
Give these guys a follow!

The owner wants to drive this car at AutoX and eventually on track.. does it look like a good idea?! What a riot.
This is literally a reincarnation of Brooke's rx7. Same color and rims. Rip to that beast.
Its going to need a lot of chassis bracing and 10 inch tires to even be competitive. It will also need cooling vents in the hood, turbo miatas get HOT. Even with a full race setup it will still get beat by miatas at 350 whp because they will get on the power much sooner with a smaller turbo.
Its an absolutely beautiful miata and great sleeper setup, but it will be a handful on track.
What a beast, great turbo choice
Wow "Miata Dad" himself! Thanks for watching Greg.
Hey greg hope your having a great day
Hey Greg! How much power will my 5 speed and lsd hold?
@@oscarlainz The 5-speed becomes a roll of the dice above 220-240wtq, and that's assuming no abuse (aka wheel hops and clutch kicks). The 1.8 diffs have been know to hold well over 350wtq, the housing itself is the weakest point. Options are upgrading to an n/a FC diff housing or having plates welded into the stock ears.
Isn't 470whp with a 2860 kind of on the really high side ? I feel like most 2860 builds I see have like 350-380 max
I understand if you don't really wanna reply since you're basically a public figure and calling out people on their lies wouldn't really be a good thing to do for you
No roll cage in an NB is terrifying
In every Miata is terrifying
Why its not gonna roll over
@@lamydora457someone can roll over it
@@lamydora457that’s what I said.. until a brake line backed out and I hit a fence post😀
No roll cage with almost 500hp is ballsy
my old boss had an mx5 convertible, it was always well looked after and i always had to marvel at the car. but this one is the best mx5 I've ever seen!
THIS is how you do a car. Exterior mods just a nice paint job and a good set of wheels, all the real mods in the suspension and engine bay.
You can do both afaik
Surely this is boost by gear or speed. It shouldn't hook in 2nd with that power. And no roll bar? I feel like I need a roll bar in my stock nb let alone with that much power. Each to their own but this is sketchy...
Hard dog roll bar was purchased but was still being shipped unfortunately during the video. Car is also tuned to hit full boost only at 3rd, 4rth and 5th. 1st and 2nd gears are completely dialed down to achieve traction. Thanks for supporting Marcus and his channel. Hope you enjoyed the video.
@@arv3410 thanks for the clarification. Makes a lot more sense now👌
@@timkramer4008 all good brother 👍
sold my 986 kept my 91 NA for the same resons as him, supercharged the mx5.........no regrets' cheers from New Zealand
That 470whp looks pretty tame.
It's not 470
Absolutely no way. Mine is 350 and way more wild. He doesn't give alot of key info. No compression ratio. No boost numbers named. He said the wrong name for the turbo. No coolant reroute. This build is trash and the dude is lying
@@LiveToRidee right!! no such thing as a 2680. It's a gtx2860r if anything.
And also you don't fit 225's on 15x7" RPF1's.
You can even see that the tire says 205 if you pause in 1080p at the right moment of the side view
So yeah you're probably right. I didn't even think the 2860r would make much more than 450whp. And the transmission definitely wouldn't last long at above 350wtq if it was a 6speed. Of course that depends on how it's driven and what type of clutch is being used (sprung or unsprung) and diff/engine mount bushings. Miata 5 speeds don't last long over 240wtq. And the only way to make a 6speed last long is to use a sprung clutch and keep the wtq under 300wtq. What was it he said, 450+wtq??! Lol
It's possible with the built bottom end and if he lowered the compression to 9:1 vs 10:1 stock but the vvt cylinder head comes with some of the weakest valve springs compared to the 94-97 valve springs so that's quite a bit of force against the intake valves even at 7k rpm. The main thing here though is the transmission lol that first and second gear WOT would've blown both 5spd and 6spd had it hooked. And you wouldn't hook 2nd or 3rd with 450+wtq.
450tq at the crank is more realistic
Anyhow shade aside just having posted a comment will help the UA-cam algorithm lol and it's a nice clean build and it's cool to see he's happy coming from the Porsche boxster
My only criticism is to try to be a lot more accurate on the build details
@@Nasonix2 yeah its really annoying. I wish he would of given factual information. It's obvious he paid someone to do all the labor. Its a shame the channel owner didnt recognize all the flaws. When I clicked in the thumbnail I was expecting to see a miata that was way better than mine. What I see here In this video is one that is much worse. I have the VVT head and it's crap. He's absolutely not making 450+ with a stock VVT head, and manifold. He'd need a bp4w and higher RPM to get 450+ also at 470whp hes not going to have 450wtq. That isn't bow a 4cyl works
All of this is totally right, turbo name being wrong aside (and max flow of the turbo he meant to say prob makes 450 with the exhaust wheel almost popping out), I have a built 2.2 stroker running an efr 7670 (4b11t)running 35 psi and my wheel tq is 520 and whp is 625, so now way in hell a smaller displacement non stroker motor will make as much tq as hp.
Even at stock power levels, the NBs I used to have had noticeable cowl shake. The chassis would benefit from a proper roll bar and the Flyin' Miata butterfly chassis brace too. Better stiffness and safety all around.
Hard dog roll bar was ordered but unfortunately was still in shipping during the video shoot. Definitely doing some chasis stiffening in the near future before doing any auto cross. I appreciate all the suggestions and criticisms as I keep learning about the trade. Thanks for watching the video and supporting Marcus' channel.
another high power green mazda on this channel ofc this feature couldn't be anything but great 💪
Thanks Dylan!
i appreciate that hes in bc
ripping the roads here are awesome
I love when you guys have more personal reviews where the owners have a chat
Yes! Should always do that. Petrolicious does that and I love it.
Nice to see a BC Miata making big numbers!
Nice ! That paint suits the car so well with those wheels. 👍👍
It’s a wrap
The early Miata engine is built on the turbo mazda hot hatches of the late 80s'. That engine has oil squirters unter the pistons and a pretty stout bottom stock...not 500 hp stout, because that is just crazy, but double stock horsepower? Sure, no problem. Over about 250 rwhp, things start to break. How's the rear diff? A Cadillac CTS rear pumpkin was a popular swap for higher power levels.
with that power I think you need that roll bar...stat
Yeah because then you can have something solid to smash your head on🤔
@@R03333 it's more about rolling the car by going too fast...hence roll bar
first thing I did when I bought my NB was install a hard dog roll bar. It’s still a small death trap of a car, but now at least I have a chance of survival if I roll over god forbid. The added chassis rigidity just from the roll bar alone is also really noticeable.
@@monstercameron you have a hard time rolling a low slung car like a Miata on the street. In addition to this if you are in such a situation where you could roll it (off a cliff or something) then the rest of the car is still made of tinfoil. But more power =\= roll bar, depends how you use the car.
Omg no wonder the car was a wet noodle lol
Anyone bashing the roll bar recommendation needs to look up what it looks like when u loose control on a back road and run the Miata up a ditch or bank on the side of the road to have it land upside down. Warning. You don't want to even see.
Not only does a roll bar fix a lot of the chassis flex and handling it also will save your life and the passenger. There's foam padding that's meant to go over the main hoop to protect yourself from it when it's driven on the street without a helmet
how's this planting 470 on those bicycle tires i feel like it should be spinning tires in 4th at that power level on those rubber bands...? also at 470whp, i'm suprised this guy didn't give us the run down on his trans and diff situation? or did he? I skipped through bc it's kind of a long vid, i'm genuinely interested in the trans and diff hes running though.
Stock trans and diff and surprisingly still holding. It's also boost by gear. 1st and 2nd gear doesn't hit full boost to allow traction.
@@arv3410 Show us dyno numbers my man. This is nowhere near 470whp.
What a bad ass Mata! Makes all the sounds!
That much power and no cage ? Fuck that lol 😦
🤣
Same thought.
Cages are for birds and rodants 😂
Cage is for domesticated animals!
Homie is really talking about MORE POWER?!
Not all heros wear capes… the just go Stu-Stu-Stu!
Little happy car that full of anger.. xD
So awesome, I'm lost for words...
As a turbo miata driver I don't understand how the 225 tires are hooking up at all.
Yeah... was looking for this comment. Thing should not be getting any traction at that power level especially in the lower gears
Yep, I have driven a 420whp miata on 245 ar1s WITH boost by gear and tps and it is significantly more rowdy than this.
@@NippyMoto I bet street gas tune is very conservative and E85 is full send but not used in the video. Stock trans, axles, diff and driveshaft wouldn't hold 500whp long. You also would be goofy to drive that power with stock brakes....
@@ryanmccormick I've read many forum posts of racers saying stock brakes with minor upgrades hold up very well on these cars. Upgraded pads, quality rotors, steel lines and good fluid go a long way.
Previous owner of my NA miata took it to the track often (fun not competition) and only ran upgraded pads and he said he never had an issue. Just be sure to change fluid more often.
Car is tuned to only hit full boost at 3rd, 4rth and 5th gear. 1st and 2nd gear are significantly dialed down to achieve traction.
Nice clean look. Gorgeous.
Such an awesome NB. Sick. Just nasty. Love it.
Little miata is crazy.
What boost is it at? Looks rather timid for 470WHP
Do you think it's faster/better than bobs mr2 mk1.5 with the 3sgte you driven?
First off cool video awesome car lol but I was cringing for the transmission at above 350wtq lol
Also it's a Garret gen2 gtx2860r incase anyone wonders. Not a 2680r lol no such thing.
And also you can't run 225's on 15x7 RPF1's lol it even says right on the tire that they're 205's... So much misinformation haha but still nice car
Thanks supporting Marcus' channel!
Full disclosure, I completely butchered the turbo during the recording lol. And yes I still have lots to learn about the car but I get a lot of help from Evolution Auto. I try my best to learn on my own by watching other people's builds and ask a lot of questions from the car community.
The rpf1's are actually 15x8's on 205's. Marcus got the tire size wrong lol.
I am running stock tranny, upgraded clutch, 1000 injectors which was not mentioned in the video. I also have a hardtop but the wrap wasn't ready during the shoot. Also had a harddog roll bar that was in transit. I didn't expect to make this much power at all with 22lbs of boost but we aren't going anymore for now since I'm running a stock tranny. I appreciate the comments good and bad. Hope you guys enjoyed the video and thanks for continuing to support the channel. Il post the dyno results down below. Thanks!

Man that thing looks fun !
Wondering what transmission he has? Is it stock or the BMW trans and what rear end to hold that much power
I fucking love nfs underground 2, playing split screen at my friends house is the best feeling in the world
No water Re route and what gear box you running for that sort of power lol
Would love to see the Dino graph
Thought the same. He didn't build it himself though- so it was probably something the shop thought they could leave out
I'm not calling you a liar but I'm gonna need to see the dyno for proof. I find it pretty hard to believe, on stock intake, TB and a log mani that it's making 470 to the wheel.
Coolest paint color name, Wasabi Green.
That's my man wasabi from Instagram! I love his build!
his numbers are inflated because the correct data was not inputed correctly on the dyno. I checked the website on the tuner and they listed it as having a 3.33 rear gear - if its a usdm 5 speed its a 4.10 if its a 6speed manual its a 3.9...
with that said the difference in power is inflated 20-23%
I have a 350 whp miata and on those roads with those tyres the car would be wheel spinning like crazy if it was over 350 ish. However, lovely car none the less.
Only can say goodjob for the owner 😎
what exhaust is that ?
During 99 there were only 4 cars that made 400 at the wheels and was daily driven. 1 was a na miata, a acura integra gsr, Mitsubishi eclipse gst spyder and a Nissan 200sx sentra. Man, now you can build a car like ordering a pizza, while we had to make our parts and while on a top ramen budget. Y'all can thank us😁😂😉 for your abundant of parts available now.
I can't believe you don't have a cage, or at least a freiking roll bar on that thing... nice car though man
On throttle...game face on
it looks realy Clean but maybe in a nother Color, it wil looks much bether!!!!👍🏼😉👌🏼
Is there a full build spec on this car?
This road is awesome. Where is it located??
If he likes mid engine he should have bought a mr2 spyder. I'm in the middle of building a turbo one. It's a great car
You should check out my Mazdaspeed 6 twin scroll turbo / dual wastegates , would make a great video when it’s done this year ;)
Which part of Canada
Never mind plates are British Columbia
You know a car is fun when the guy reviewing the car begins to giggle like a school girl every time he lets off the throttle.
Nice Color
Bananas have potassium 🍌
What color? Love the color
Wasabi Green
Great build, but nothing sleeper about a lime green miata with the swoosh of the turbo
and it looks much bether in the bmw e36 black, our in white with 16ns with 9,5zoll rims on et25 our et30 to build the Wide fenders from the new miata ans to'be real a real dip car !!👍🏼😎👌🏼
Epic little Mx5, I've been driving around in a friends SC ND and it was good fun, was missing a little punch though. Are you sure this ones 470whp? seems more like 370whp
instagram.com/p/COak6OpHAog/?
Seems more like 270whp
LETSGO818 settle down boy, your mustang ain’t that fast
@@ButtKickersReviews I never said it was
@@arv3410 thanks awesome car and i definitely don’t mean to come across the wrong way it’s just it didn’t seem like that much. I know that turbo would really be struggling to make the power too, far past it’s efficiency point. FYI i’ve got a 430whp turbo lotus elise with the same turbo on e85
Stock brakes with such power? No bueno…a good upgrade path to shave some seconds and add confidence, if you ask me. ;)
That thing needs a roll bar ASAP
What exhaust is this thing running?
3inch HKS with a resonator
The car weighs about 4500 pounds when you factor in the weight of the owners’ balls.
I built an NA Miata with around 350whp, and the owner only wants 500whp for bragging rights. He doesn’t even have a proper alignment. This car was ‘built for the gram’ and somehow ended up good. That’s my take on it
Appreciate the people who turned the wrenches, but get the feeling the owner is not one of them.
Is anything done to the head?
Nothing done to the head as of yet.
very pretty!
No roll cage????
Cab you post dyno results?
Dyno results are on this link below:
instagram.com/p/CRbgrPGLWwp/?
Lol friend had a monster 1983. Most terrifying car to ride shotgun in. I made so many deals with God.
Super clean, but 470whp? Huge doubt, that thing shouldn't hook through 3rd with those tiny ass wheels and tires.
no roll bar?
no chassis stiffening at all?
only has pads?
z flex coils?
450-500hp?
225 tyres?
yeah no thanks
cool car but he went about it in the complete opposite way most people should
He did it for the gram, and got lucky. Never even bothered to get it aligned. He wants 500whp for bragging rights. Clown imo
@@ButtKickersReviews yeah I wasn't going to say it but it's pretty obvious that he just wants dyno numbers for the big dick bragging rights
The power absolutely outweighs a few of the other supporting mods. Would love to see some flares, fatter wheel/tire setup, and a some chassis bracing. I am concerned for the owner's safety as much as you are haha.
Who gives a fk its not your car 😂😂and all those things you mentioned are useless its not gonna improve power its just gonna make it heavier 😂😂
he needs wider wheels lmaoaoa
Fantastic engine setup....the other stuff not so much. Much better coils out there, needs chassis stiffening, and for the love of god unplug the antenna. Looks like a damn rc car. Lol.
Why instead of continentals he doesn’t get advans
470whp... ?? never.....
Just missing a roll bar :)
naisu
Doesn't seem like 400+. I'm at ~200hp with a piggy backed Garret 2560R and I break loose a lot easier, w/ 225's.
I don't think anyone believes the 470 number. But my NA is on 205s and making 225 WHP/210 torque (dyno tuned) and can't break loose at all. The tire compound is way, WAY more important than the width.
Cool miata but that is a 400HP turbo , lol how is a 2860r making almost 500 wheel . 🤔
$20k Power
$0.00 Rollbar, harness... brain.
Why its not like it can roll 🤦♂️
get this man some center caps!
In car camera is garbage. Just use a gopro. Other than that great video
All the Miata guys know, this is not 470 whp
That's not a big turbo... My GTX2871(82A/R) isn't even a "big turbo" for my 95 Miata. The GTX3582 is a big turbo for a 1.8.
So what size you should recommend me I got a 2002 NB Miata mx5
@@samuelherman4859 For decent spool, street use... would go with GT2554, GT2560R, or GT2860R (or the GTX equivalent).
470? more like 270 wtf this dude on
Thats car needs a roll cage.
Its 50/50 weight distribution will never have a miata kick out on you i drive one its not a mustang lol
No cage, and no uprated brakes eek
It wasn't the most calming drive.. that's for sure
This is probably low 300s absolutely NOT anywhere over 400
this car is absolutely not making 470whp that prob around 200-300
Looks like about 340 wheel to me. 100% not 470 l m a o
Stop the video at 9:31 and look at the sidewall of the tyre..... clearly not running 225's!!!
lmao he should probably stiffen the chassis
really 400?? hmmmmm
Dragon?
Its a scary ass deathtrap when its over 200hp its also easy to make that power with a 300$ turbo kit from ebay
Spoken like a true keyboard warrior, who’s never built anything. A guy like you would become a statistic in one of these with 300whp
There is no way that's 470whp
Why spend all that money on drivetrain and grab $700 coil overs and no rollbar, cooling improvements, or chassis reinforcement? Wasted potential.
This claim is so BS....
470whp,BIG TURBO...
2860 ie Disco potato has been used by everyone for years.
Theres new tech now. Try a G25-660 Efr6258 or a bunchbof others
That car needs a better tune
Maybe 300whp
Its making 190hp at most
can i just say who tf decided to drive a 470hp with fucking tein flexes. teins. smh
