ND Miata Skyactiv engine teardown

Customer had us replace their motor in their 2016 ND Miata, I figured I'd take the opportunity to do a teardown and see how these engines are built. I took the opportunity to do some comparisons to the predecessor - the Ford Duratec - as I'm very familiar with those.

Love the work. And in HD, i was able to zoom in and see in full detail. I haven't heard of these engines fail on their own, so i was interested to see what went on.

So little content on (modern) Mazda engines on YouTube. Thanks for doing this!

I been waiting for one of these vids! I supercharged mine.

Danke für die Dokumentation der Arbeit. Gut erklärt 🙂

After trying to install performance camshafts myself with no prior experience this video saved my life, redid the timing 3 different times while also checking and dealing with a handfull of other issues (100k mile engine) turns out the little (pump piece) in the rear main housing fell out and the car will NOT start at all without it. I was only able to find out where it went becuase of this video! Just watching through looking for something that looked similar! Now the car runs and drives on the new base map tune!

Wow! What a fantastic video! Thanks for putting this out there.

Great Video! I like that you don't fast-forward anything. I have a 2017 ND Miata with 80k miles. No track or street abuse. Will it have build-up like the one you did here? Is there anything you'd recommend doing besides regular oil changes? I'm not super knowledgeable on engines. The only thing I did to it is clean out the throttle body and do oil/filter changes. I take it easy on her but is it true that it's good for the engine to get the RPMs to redline every now and then in good conditions? Or is that just a myth?

Hey man, I REALLY appreciate this video! Not only is it super interesting, but incredibly helpful!

Long shot, but just thought I'd try asking. Is it possible to remove the oil pump without taking the chain completely off? I suspect my ND spun a bearing, so I'm attempting to replace them with the engine still in the car, but I didn't realize the oil pump would be in the way of cylinder 1 until I got the oil pan off 😢

Very cool to see this. Is this 2.0L SkyActiv-G the same, essentially as the one found in the third generation Mazda 3? (I know the one for the Miata is higher power )

I just turbo charged my 2016 with the B.B.R 200 cam kit with heavier valve springs, I've heard they can handle up to 7-8 lb boost and 240 lb of torque stock.

So this is an ND1 engine. The ND2 has a few differences, mainly pistons. Did I miss when you said how many miles were on it?

[hakitup]

Can the engine come out the top of the engine bay? I'm guessing it has to go out the bottom if you keep the transmission attached to it.

[flyfishaholic]

I have very limited mechanical experience, so this may be a dumb question. If an engine has direct injection, why are there intake ports as well?

[alexha]

Weird question but what are those shoes you're wearing? They look comfy for long days on your feet.

So, I assume you have disassembled the 1.5l Skyactive-G, correct?

I am interested in the balancer shaft in the Skyactive-G 2.0l engine. I have Mazda6 with this engine, and I am wondering if it has a balancer shaft. From the information in the internet, it seems Skyactive-G 2.0l in Mazda6 does not have a balancer shaft. On the other hand, some people claim, that Skyactive-G 2.0 in Miata does have a balancer shaft.

I would appreciate any information. I have Mazda6 2.0l Skyactive-G and I suffer from engine vibrations. Dealers say that all is good, and I would like to understand what is going before selling the car or requesting repairs.
