Anatomy of a Miata 1990 - 1993 (NA6)

[@agkracing140]

THANK YOU SO MUCH for putting this video together. My daughter purchased a 1990 Miata and in less than one month from her purchase, I purchased a 1993 Miata and my son purchased a 1991 Miata. I had no idea these little cars were so addictive. Your video helped so much with identifying certain parts so I know my way around the NA a little better. I'm so happy I found this. Subscribed!

[@immortanautomotive9221]

Glad you enjoyed it, thanks for the support!

[@buchyvon]

Really appreciate this video. As the owner of a 1990 NA6, I'm happy to hear that the short nose crank thing isn't really a thing (if you follow directions).

[@lamontgilliland9664]

Thank you for this detailed video. I have owned my '93 NA for almost 30 years now, and you your video has gone over several things I did not yet know. : )

[@lilmike2710]

I'm a new owner of a 93. Well, the thing is, after I bought it 7 months ago, I fell head over heels in love with the thing . So I bought several more 😁 I have a strong feeling that they're about to skyrocket in value and I expect to get a big return on my investments. Especially since I was able to acquire them all for a song. I paid $1500 for the first one. Scored the next one for $1000. I got my red one for a paltry $850 from some junkie that was putting $2 worth of gas in it. 😏 Yea, no I don't feel the least bit guilty. He was paying for the gas with pennies and nickels so I knew I had him... Anyways... I've always been a Chevy and MOPAR V8 guy and I never thought I'd enjoy owning what I used to consider a girl's car... I remember throwing shade on Miata owners. I'd say "Miata... for when the rainbow stickers just don't say it loud enough." 😂 Just saying... I love my NA 👍 It's my favorite car now.

I drive an hour and a half to have Chris work on my 90 and am glad to do it. The best in customer service and care for my Mariner Blue Miata. Love me some Immortan Automotive!

[@benchleyfalconer-kc5hj]

Brilliant! Thank you for this. Great presentation; straight facts, no fluff. Very appreciated.

[@ZeeCayPeeA]

just purchased my first all original 1990 NA . I like to work on my own cars , thank you for the video .I now know where a lot of the important parts are located. real fun car to drive and easy to work on.

[@immortanautomotive9221]

Glad to help! Let us know if there's anything you'd like to see a video about in the future.

[@grandtheftauto1233]

How’s the Miata

[@BokBarber]

This is an excellent walk through. I'll be sure to double check that ground on the PPF.

[@xeimaras8]

OUTSTANDING! The most informative Miata video I have ever seen!. Thank you Immortan Automotive!

[@immortanautomotive9221]

Thank you 🙏

[@adri1leusha]

I drive my miata in all temperatures! I'm glad to learn about the iddle control system... It was not clear to me what all the tubes were for, as you said, 1.6 specific...

[@anthonyhitchings1051]

Much appreciated - our 1992 is still running well.

[@rowanhealy]

This is great, I have learned a lot about engines since decided to buy an MX5 to put a turbo into but this is a great overview of all of the parts of the engine, appreciate it!

[@immortanautomotive9221]

Thanks! Happy to help!

[@hamzterix]

Awesome video. Very unique and appreciated.

[@gabe2good220]

Thank you so much for this video, I had a pretty good idea of the car anatomy since i stripped mine down to a shell with suspension but this video really helped me out.

[@madigray418]

Amazing video! Thanks so much. Just bought a 1993!

[@Chris-yq8oz]

Excellent video. My 17yo son just bought a ‘91 so I need to learn this car now. He wanted to pressure wash the engine and bay, now it won’t start 🤦🏼‍♂️.

[@immortanautomotive9221]

Honestly I’ve been there too 😅 gotta learn somehow

[@GridQuestions]

Thank you for sharing this wonderful video, it will help me a lot

[@bornfree2000]

Great video! Very practical and well done.

[@immortanautomotive9221]

Thank you 🙏

[@scorchez]

Fantastic overview. I learned a lot.

[@absolutecarpetcare6696]

Great video. Very usefull.

[@funretirementprojects7765]

Wow! Great job!

[@immortanautomotive9221]

Thanks!

[@one234569and10]

Lots of good information, however I wish you covered the one thing I need :D - AUTO TRANS - there is a Trans. Vacuum Modulator (I can not locate it). Everyone says its a common replacement however there are no videos on how to on line or where its located.

[@immortanautomotive9221]

It’s on the driver side towards the rear of the transmission, looks kind a like the cruise control actuator with a vacuum hose going to it

[@gerkeane5626]

Great video 👍

[@immortanautomotive9221]

Thanks!

[@chrissss999]

Very helpful!! Thankyou

[@plmbih1]

Thank you! Very knowledgeable! Now I want to bring you my Miata to get it running again! 😅

[@brookrayner]

TEN stands for Test ENable .... short to GND when setting timing and idle RPM on a warmed-up engine

[@LaserMaster332]

Stupid question: I need to adjust my TPS. Where do I insert the feeler gauges? Like where is the throttle stop screw? Is that bit at 5:25?

[@immortanautomotive9221]

No that’s the dash pot, the throttle stop screw is on the other side, hard to explain, I would think google image search would give you what you’re looking for.

[@jackuaro]

Great title!

[@McGregor007]

Hey man. So what’s the black can/fuel filter looking thing with vacuum lines going into it. Near the coolant overflow reservoir.

[@immortanautomotive9221]

It’s part of the “evap” system, which regulates fuel tank pressures and venting

[@lasvegascrisis]

i gotta say the slave cylinder IS different, there is an early '90 style with the nipple on the slave cylinder rod, & a later '90 & the nipple goes into the clutch fork on the early '90 NA

[@KSCPMark6742]

One thing I have learned from watching a log of these kinds of videos is that there are so many versions of this car. There is no such thing as a standard NA6.Mine seem to have so much extra stuff, don't know what is "standard", A/C, cruise control, power steering, antilock, probably more crap. Apart from the engine block and the fuse block there is little similarity between mine and this car.

[@crow578]

The magnetic CAS module is the same as on a Ford Escort, where it's only $40 as opposed to $160.

[@Karuiko]

Nice breakdown. When can one be expected for the NA8?

[@immortanautomotive9221]

Hopefully soon, I waiting for a good example to show up at the shop lately most of them have been missed I try to use stock ones for the videos

[@therealspixycat]

Thank you for this very helpful video. One question: is the 1.6 na engine an interference engine?

[@immortanautomotive9221]

It is non-interference, no harm can be done if there’s a problem with the timing belt

[@therealspixycat]

@@immortanautomotive9221 that is great to know!

[@punchbush]

How different is the NA from the M edition? Thanks so much for sharing your passions!!!

[@immortanautomotive9221]

All M-Edition cars are NA cars. NA just means it's a first generation Miata made between 1989 and 1997. The Anatomy of a Miata video for the 94-97 model years details what is unique about the M Edition.

[@utube4greenfuture]

THE BEST and most thorough explanation of the Miata engine. Nicely done. Much thanks. Question for anyone out there, I took 93 Miata to the shop to change the timing belt and hose replacement kit. Now the system idles at 1600 to 1700 RPMs. The idle adjustment screw is bottomed out. I dare not touch the "No Touch" adjustment bolt that's set at the factory. Any advice for a Marine Corp veteran owner to solve this issue? Liked and subscribed.

[@immortanautomotive9221]

Use a timing light to check ignition timing, if that looks ok it’s possible they put the belt on wrong

[@utube4greenfuture]

@@immortanautomotive9221 Thanks for the reply. I'll get a timing light. Another clue I found that when I turn on the A/C, the idle drops to the desired 850 RPM. My Idle air control valve mounted below the throttle intake manifold has a two wire connector but mine only has a single wire. Should it have two wires?

[@utube4greenfuture]

I forgot to mention that the check engine light is giving 3 long blinks and 4 short blinks when Ten and ground is shorted. I tried the Reset Procedure (disconnect negative from battery for 30 seconds) but it didn't clear it. Have you ever disassembled and cleaned out the idle air control valve below the throttle body? What did you use to do that?

[@spiralcoronet]

Awesome video! Will you do one for NA8?

[@immortanautomotive9221]

Yes coming soon!

[@davidtodd4035]

What is the black box on the far drivers side, out board of the clutch master clyinder? It has a plastic cover and the inside looks like electrical connection

[@immortanautomotive9221]

There are a couple relays in there, horn and lights if I recall correctly

[@grandtheftauto1233]

Is there supposed to be a cover over the wiper mechanism (crowl) on the driver side

[@immortanautomotive9221]

Nope, only the right side covering the motor itself

[@grandtheftauto1233]

@@immortanautomotive9221 thanks man! Recently got my 90 Miata and it is really rust free. Has some decent oil leaks on the CAS and the VC, probably front main seal too but without any rust - it was a steal

[@prometheus1901]

Thank you! Very helpful!

Can't say Thank you enough for your thorough video!!!❤❤❤❤❤😊😊😊.

[@mathieubourbonnais7421]

Am I the only one that got the huge windshield washer fluid bottle? How can I get the small one please

[@immortanautomotive9221]

I’m not sure exactly, I think there’s a different one for cars with ABS or without?

[@GRINHELL]

Europe's got the bigger ones, the smaller are in miatas.

[@crawford323]

What about the dreaded plug? under the crank angle sensor? What a rotten thing to do. I have not a clue to why they plugged an unused coolant port from the 323 engine which is what they used ( with a change of cranks ) When that little rubber rubber goes, you lose all of your coolant mighty fast. Replacing it is a royal pain in the tushy.

[@immortanautomotive9221]

I actually don’t see those fail very often, one trick to keeping that plug “healthy” is stay on top of any oil leaks you have. When oil gets on any of the rubber parts it softens / weakens it.

[@crawford323]

@@immortanautomotive9221 Mine finally gave it up after 31 years and 5 owners. It still is a very bad move they made with a quick fix. But, guess what? Mazda still had one in stock. Having said this, I do not know what can be done to plug it with something else. What would you do if you were faced with that part being “ retired?”

[@immortanautomotive9221]

I’d get a universal one from an auto parts store for $1

[@crawford323]

@@immortanautomotive9221 I am glad there are simple options available then. I was not aware there was. Good to hear. I expert trying to explain what you need to an auto zone would be difficult. Here is a retire part which I ended up having to machine. My Miata does not have power steering and it body developed a rattle which I misidentified as a bad shock or a ball joint. After chasing the problem, l found after taking the right side inner tie rod boot off, shards of deteriorating plastic was found. This was what was left of the bushing which centered the rack and pinion rod in the housing. My efforts to find that part was not fruitful. So I made my own.

[@immortanautomotive9221]

Shoot me an email at [e-mail] if you want to make more of those bushings and sell me a few, I’ve run into that problem as well.
