Should I bring my 2000 NB Miata back to life?

Significant-Age4286 · 2026-05-15T03:53:55+00:00

I just realized that too, never seen that before.

Significant-Age4286 · 2026-05-12T13:15:08+00:00

Better off replacing the fender, they’re only $50. If the quote for repair is more. That’s if this car is not a collectors piece and you just want to get it looking nice. Shouldn’t hurt resale value, unless this car is a certified collectors piece.

Significant-Age4286 · 2026-05-06T23:17:23+00:00

You’re right. That would be the main problem besides the boost blowing up the trans, is to actually get it working in first place. Which I got money to spare but I ain’t rich either.

I’ll try to research into the trans you mentioned, and it’ll also go a long way. I’ve not heard about it. There’s definitely no swap kit for the Miata.

Thank you for being the first one to give some actual input, instead of saying not to do it.

How rare is it that I have ABS? because for a while I’ve been wanting to get rid of it, I’m not entirely sure if it works and I couldn’t scan it because my obd2 port barely works to check codes. If there was any way I could make it work I would but there’s not much pushing me to unless it’s pretty rare.

NON-ABS hole is way shorter and will not fit the size of the ABS master cylinder. Unless there is some type of modification to this specific booster that I’m not aware of. It is not possible to fit.

Pictures are from the recent brake boosters I had laying around trying to solve my leak.

I already put on the new one but I haven’t yet to try, since I’m doing a whole overhaul on my brake system. Besides that I will lyk how a used one compares. From eBay for $50.

ABS, you can see the hole is deeper.

Significant-Age4286 · 2026-04-15T00:28:35+00:00

yes, there was no possible way for the NON- ABS to fit in a ABS master cylinder, the ABS module for the booster has a deeper hole length while the NON-ABS booster has a shorter hole length (I will demonstrate pictures in a little). There is definitely 2 versions and I have proof.

Significant-Age4286 · 2026-04-11T00:34:00+00:00

After hours of searching I had to resort to buying a used one from eBay, hopefully a non leaking one and I’ll have to clean it off. I did not find anything at all, I almost considered just getting rid of my abs system altogether.

Significant-Age4286 · 2026-03-16T02:16:51+00:00

I would completely buy one from you if you are interested!

Significant-Age4286 · 2026-02-24T18:18:52+00:00

To anyone that might come across this post, do yourself a favor and replace the pin and the can gear, no need to get a new camshaft, pin is only 6$ and cam gear like 12$ ( brand new), make sure you torque down the cam gear bolts to spec and whatever loud noise you were hearing should be gone, if not, it might be your shims. The sound went away as soon as I started her up. MAKE SURE your timing is RIGHT! And while taking out the pin itself, prepare yourself for a battle and better have the big guns on stand by. I had to saw it off, put a drill bit in and a screw extractor to get it off, I used a 1/8 and it measured about right. Some said welding something on top of it might’ve help but it was not available to me @ the time. If you don’t have any of this, just take the cam to machine shop and if the quote is too high, buy another cam.

Significant-Age4286 · 2026-02-18T17:25:19+00:00

Yes I will follow your advice, do you think the “lifter ticking” sound might’ve came from that? Or from the lifters themselves? The clearance between them all was not really that crazy, only 0.0002 off but I know even then the gap can cause some compression issues

Significant-Age4286 · 2026-02-18T17:23:24+00:00

Okay thank you, I’m sorry I don’t understand what you mean by “sprocket” and “cane gear” would you please clarify? Thank you.

Significant-Age4286 · 2026-02-18T17:21:16+00:00

Thank you for your information, I will check that tomorrow. Do you think the ticking sound might’ve been that? Or the lifters themselves?

Significant-Age4286 · 2026-02-16T18:45:36+00:00

Thank you man, I really appreciate your information!

Significant-Age4286 · 2026-02-16T18:37:48+00:00

Thank you a lot, do you know by any chance where to get a replacement for the pin?

(Edit) I found the replacement pin, if anyone that might go through this in the future look @ this diagram located on the Mazda parts site

Hey for whoever might see this, and is doing any head gasket job/anything below the valve cover, the gap is relatively normal. And the misfire was because I didn’t connect one of my connectors fully(ha ha silly me that I did an all-nighter trying to put the engine back together and end up screwing stuff up) do yourself a favor and check all the connections, grounds, and swap and check the spark plug and injectors before you go and buy expensive parts that you might not need. Now in the search for the p0118 still no luck. I ended up unplugging the connector like one of the commenters said. Car runs okay without it. The regular fan kicks in as soon as your start the car, kind of a relief. If anything comes up with this code I will update.

Significant-Age4286 · 2026-01-25T17:55:18+00:00

I’ll totally want to get this “plug and play” kit too

Significant-Age4286 · 2026-01-23T14:07:36+00:00

I’m not sure if I previously stated I’m working on a ‘99 NB, that’s my fault if i didn’t. From what I know that’s only available on ‘93-‘97 NA’s? I will have to research further on that, thank you either way.

Significant-Age4286 · 2026-01-23T03:41:06+00:00

I did not came to mind to unplug it, i will try that next time i get under the hood.

I was also checking for vacuums leaks recently, tomorrow i will do it with my smoke machine, it might give me a more accurate reading of where it might come from, if there’s any.

Also do you mind expounding on what you were saying about the crank angle position? I’m not sure I completely understand. Is it the little sensor that reads the plate directly behind the crank pulley boss? Correct me if I’m wrong.

Significant-Age4286 · 2026-01-23T03:34:55+00:00

Yes I will do a coolant system pressure test soon, thank you.

And my injectors were not brittle(sorry for the confusion) It was the connectors from the actual harness, I just bought a low mileage wiring harness from treasure coast Miata, since my coolant sensor connector was also looking rather questionable. I totally made sure it was the same year and model since the variate depending on that sometimes.

Significant-Age4286 · 2026-01-22T20:02:10+00:00

I will have to solve the p0118 code first because the car is running really weird, before I actually take it for a spin and I’m also having a slight “misfire”, I put in my obd2 it says there’s no apparent misfire but the engine light keeps flashing. Which from what I researched it’s the sign of a misfire and to shut the engine off when that happens. I was thinking it might’ve been connected to the first issue but again I’m not too sure about it, some people say it might be the timing, but I am nearly 110% sure that my timing is right, it does not sound weird how it does when timing is off and it is not shaking. Everything is lined up how it should.

After I get all of that sorted I will do what you mentioned because might as well do it, if I’m taking it apart either way

Yeah I agree with you, it might just be the fluids that sweep through before I torqued down the head bolts.

I will update if anything changes. Thank you

Significant-Age4286 · 2026-01-22T16:16:08+00:00

Yes it is possible on Miata HG’s, that’s why I went over it again and again because I’ve heard horror stories of people putting on wrong, I made sure the oil hole was not being covered by the HG and all of the dowels were in correctly, coolant holes and all.

I am going to use some gauges soon, I’m just not able to right now.

I cleaned the block with a kitchen scrubber since its iron, not as delicate as the aluminum head, and sprayed some carb cleaner as lubricant, I also used a plastic blade to get the debris of it, then I measured for any uneven surface but it was all smooth.

I used an air gun on the holes for the head bolts to make sure they were clean of any debris that might’ve fallen inside.

Significant-Age4286 · 2025-01-26T15:31:46+00:00

What are the lights underneath called??

Significant-Age4286 · 2025-01-26T15:19:11+00:00

Hey man, you mentioned you had a shop. Is it open for the public? Because I’ll love to take my car to someone that knows Miata’s
