Now this is a video the internet was in need of

Good reference! Expecting this to blow up in the community lol

Great stuff, Brendan! You should write up a written version of this for quick reference - that would be SUPER handy!

THIS is QUALITY CONTENT.

Thank you! I’m looking into getting a Miata, I like the NA for looks and interior mod-ability - but I like the NB for being newer and cheaper. This is awesome

Good vid!
Do have a couple corrections/extra info.

An NB1 1.8 in an NA 1.8 is an easy swap (Even easier then the NA 1.8 in an NA 1.6 because you don't need any adapters of any sort).
Just swap all the electronic parts (Sensors, injector wiring, alternator etc) of the NA engine on the NB engine.
In some countries (Not sure exactly wich but i know the US has this) the NB1 had a returnless fuel system so  you need to sort out the fuel rail. In Europe the NB1 has a return!
This way it will run fine on the stock NA 1.8 ECU.

All NA's have the big starter motor, the smaller and lighter are all NB (Even the 5speed).
Think you need to modify the dust shield a bit to use the NB starter motor on an NA gearbox and only two of the three bolts are usable. Not completely sure on this never tried this swap myself, but i've red about it.

Not in all countries the NB2 had the 6speed and the bigger sport brakes unfortunately :(

The NB uses a slightly different upper balljoint so if you're going to use the NB font hub on an NA you also need to use the upper arm.

I've compared NA and NB rear hubs. And the only difference that i could find was that the hole in the upper mount isn't in the middle on the NB hub like it is on the NA hub.
So it only has less camber and it isn't actually 5mm wider.

Sorry but i really hate that there is a ton of old/misinformation in the Miata community and it annoys the shit out of me.

I do really appreciate that at least some people are releasing some good Miata content on youtube, unlike alot of the crappy ones.

This is the single best video for people fixing up Miatas.

Comprehensive - good work.
Thanks for sharing your knowledge.
Gotta love YouTube after watching pieces like this.

Just picked up a Nb1 a couple months ago and I’ve been looking for a Channel like this. Fuckin gold man!

Great reference, well done sir!

Your videos are just brilliant !!

This was very informative and well done showing each sections at a time!! Definitely using a bit of this for my NA miatas 🙌🏽🙌🏽♥️♥️♥️

I need this kinda video in my life

Thank you so much! I'm currently swapping an NB interior and AC system into an NA

MX-5 owners clup publish your video....great

Great original content!

Love this guide, also love your shift boot and handbrake boot, very nice

Really good video with good info

Awesome video! I did a full NB1 swap in my NA1 and it was a lot easier than I was seeing. I just bought a rough NB and took it completely apart. Then swapped everything that would fit. Except the interior. I like the NA1 interior.

Some NAs actually do have ABS. Atleast in the US
