I have a 92. I’ve spent two years turning it into an NB2, part by part. I’m not done yet.

On the other hand, here in GA I don’t have to take all my turbo shit out every two years to pass emissions because it’s over 25 years old. Rwyatt’s build thread makes me very happy about that.

well I do plan on doing a turbo
a mad dog roll bar (for safety). idk the list could be small but turn into a never ending slew of things to do with the car
right now I'm working with 6 -8k looking for a car whether it be NA or NB.
as for what I want car to do? kick some ass on the road ( the car passion channels ability to walk mustangs is low key my goal) and maybe autoX. I am not entirely sure but I for sure would love to handle the suspension and brake before I go full on turbo.

I'm just in it for the general info which you guys gave me a lot of good stuff to work with.

I'm just torn. I might start NA? then go NB? I love the looks and style and charm of the NA but the nb is just statistically better. I wish there was a middle ground.

Walk mustangs?

Like stock v6 grocery getter mustangs? Cause a boosted coyote would take a heaping dump on 99% of the turbo miata's out there.. Including his, even at 400whp

....oh and keep up in the corners too ;)

But by all means, keep dreaming

Where are you located? I may have exactly what you want.

Sometimes it's hard to hear all the words unless you stay veeeery still.

TIL that all 03-05 have TF diffs. I, along with about half the internet, it seems, thought that it was just 03.

Downsides to 01-02: Plagued with VVT issues, heavy, the projector headlights actually suck really bad, especially compared to a $200 retrofit in an NB1. Also: Gurl u faaatttttt.


Anyways, i suggest an S2000.

define: vvt issues

concealer404 01-26-2018 10:23 AM

There's a TSB for the early VVT cars that to some effect says "CEL on for VVT something or other, we don't know how to fix it, throw a ton of parts at it."

Likely not something that matters with a non-standard ECU, but i've seen it on a couple cars now. Doesn't seem to run any different, you just get a CEL for something related to VVT, dont' remember the actual code. Been 2 years since i've dealt with the last one.

18psi 01-26-2018 10:56 AM

Mine had one. It was IIRC due to bad wiring for the vvt solenoid from the ecu.

To say "plagued" is a gross (pun :D) exaggeration. We're talking maybe a few dozen out of hundreds of thousands

That's also a gross exaggeration. :lol: OEMs don't issue TSBs for "a few dozen."

We'll meet in the middle at "some." <3

18psi 01-26-2018 11:11 AM

Oh no when I said dozen I meant "reported on tha interwebz", shoulda been more clear. It's entirely possible the issue is much greater, but I haven't seen it be that bad, and when I was researching it when mine had it, I found very little info and very few people complaining about it.

Lexzar 01-26-2018 11:22 AM

Will trade EFR NA for stock 01-02 miata

Fiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiiii iiiiiiine have a kitty.


But, you guys can pry my beloved NB1s out of my cold, lifeless, grubby, dickbeaters.

This is effectively what I've done as well. Had I known ahead of time what direction my car would take, I would have gone with the NB2 from the start.

i actually live in jersey man!

hquakers 01-27-2018 08:29 PM

Where in NJ are you? Plenty of Miatas around to try out to see which you like best. There's a NJ Miata Facebook group. Are you in it? Just whatever you do, avoid buying a rusty one. I cannot stress this enough.

lvw 01-28-2018 12:42 AM

I own a 91 na,I have changed out everything.It has been an 11 year process. Have you got that much time,and a ton of money? If so, go for it,if not listen to Sav! Only advantages are weight,and Va. has antique plates at 25 years.

DNMakinson 01-28-2018 09:55 AM

NB1 + HID headlight conversion + NB2 Console is good option.
Not sure value of VVT on stock rod build

borka 01-28-2018 05:47 PM

I owned all 3 generations and hands down my 02 nb2 is by far the best.

94 NA: pop up headlights, and older styling wasn't to my liking. Plus needs fender roll for 225 tires.

99 nb1 sport: good platform, chassy more flexible than nb2 and worse headlights.

02 nb2: my current and favorite miata. Vvt adds a nice torque boost, factory under bracing stiffens up the car nicely, good headlights and a bit nicer styling vs nb1.

in a perfect world I will have a red msm with a built Vvt swap and ms3. Basically all my mods in a red msm frame.

Too bad you are all the way across the country. I have an NA that is ready for a turbo kit, or making reasonable NA power.
