Hey yall. I've been here off and on, mainly in "listen mode" for the past couple years.
I purchased a '95 Miata 2 years ago and it's been my NASA HPDE car. I also plan to TT it. I do plan on jumping into wheel to wheel racing at some point. Be great to have stories to tell as I age! I was thinking of buying an SM car already built, yet think I will benefit and learn more if I build my own. I know there have been several threads on buying vs. building. I've decided on building. I already have a donor car.
My question is, where to start? I know I'll need to build it per the NASA GCR but how do I get started in tearing this "bad boy" down and building it into a NASA Spec Miata? Is there a thread that someone can direct me too.
Thanks for being patient with a Newbie!

Start by reading. This website has a great search function, make it your friend. Buy my book and read it. Read the GCR, then read it again. Even if you only plan on running NASA, read the SCCA rules also.
Plan on spending double the money you think it will cost. Plan on 200 hours of work to build a good car.
Get to know the local pro builder, you will need his help at some time.

There are several threads and blogs that document builds. Start with Wheeler's book. And get a copy of the service manual for your year. The big variables in a build are if you have the space, time, tools and mechanical ability to do the build.

+1 and with what everyone else who has already commented.
CAGE! The cage and seat are the most important thing. Identify the cage builder/installer and go from there... Then employ the wisdom from Daves book, this site and fellow SM racers in your region. Oh, and have fun! I loved building my car, liked it more than I do driving it

Here's the estimate we worked with for the bare minimum...it was close! The donor number will vary but this is what we figured.
Donor...$1500(strong 140k motor) Suspension...$1350 Cage...$1500 Radiator...$350 exhaust...$300 Pads...$220(rotors were ok) Intake(1.6)...$200 Seat/Harness...$500 Wheels/tires(found both used w/2 sets RA1's)...$400 Safety(net,extinguisher,kill switch)...$120 Hardtop...$900 First set up(alignment and corner weight)...$300 Steering wheel...$300 New fluids and crossed fingers
Total...$7940 and we were racing, granted with a lot of old things on the car! Except for the cage and set/up no labor is included as to us this was free...but above posts are accurate!!
Don't forget driver equipment(in your race budget) though...which can be a big number!

My build was not based around any type of budget, so it could certainly be done for less. But it also doesn't include any type of pro motor or the new timing and fuel pressure items either. It is for a 99.

For a starter build expect 8-10k. Mine is at about 7k but there are several things I do myself, the biggest being the cage. Instead of 2500 it's about 250. I have most of the consumables, data, seat, restraints and nets. I've stripped it to the tub and I'm rebuilding or reconditioning what I can. I got a cheap donor with a strong drive train (for that old a car) and a great deal on a used top. I've had about a grand in surprises so far, I'd imagine I'm in for another grand in surprises, at least, before I'm done.
Your big ticket items in a basic build will be your cage, spec suspension, the top, tires and wheels. That's assuming your drive train is adequate to get you to the track. At the very least make sure you don't leak, have a strong enough clutch and replace all the brake parts. Doesn't matter how fast you go if you can't stop. The rest of the stuff is anywhere from 50 to a few hundred bucks but it adds up.
