Anatomy of a Miata 1990 - 1993 (NA6) an overview of the first generation of the Mazda Miata, covering the major components and some common issues you may come across. We will be doing a series covering each Miata model.
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!
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. : )
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!
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.
Thank you so much for this video! I have a 1992 that I am trying to get to full working order and knowing the anatomy and common issues is huge. I am slowly but surely learning how to be my own mechanic and being able to correctly identify what is what is so helpful.
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.
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 🤦🏼♂️.
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...
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!
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
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.
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 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?
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?
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
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.
@@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
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.
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.
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.
@@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 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.
