I think the goon shop in Sunnyvale does K-series swaps. PR Motorsports in Hayward is a good Mazda/Miata/Rotary shop in the East Bay.

But yeah, don't buy cars that aren't smogged, aren't registered, etc. Sorry. :(

You bought a used turbo car that wasn't running well...in Cali, where it needs smogged and you can't work on it? Eek. What was your thought process?

Does it throw any DTCs? Is the car all stock? If it were me (who has space and tools to work on cars...) I'd make sure no codes are set, boost leak test it to 15-20 psi, test the wastegate to make sure it functions, check plugs/coils, then probably replace the ECU is none of that worked.

The car was running OK when I bought it. I didn't know the seller hadn't smogged it until I tried to transfer the title. There is no check engine light, unfortunately it is somewhat far away so I can't work on it every moment.

FYI: CA DMV states that the seller must smog the vehicle prior to selling. A lot of people on CL don't know/don't care about this, as you found out, but really, if they're not willing to smog the car, that should be a clear sign something's not right.

Sorry about your Miata. I hope you can get it in decent running shape. Rotorsport in Santa Clara is a Mazda specialist, also I think there's one in Sunnyvale that a prominent Miata goon works at/owns? Kinda far from the city with a poorly running car, but might be worth it if you can't find anything local

I knew that the car needed to be smogged before a sale, and the seller had told me that he had smogged it. The carfax on the car came back clean. I bought the MSM for $5200 with 70k miles, and as far as I knew it needed some interior/cosmetic work. The seller is unreachable and was dishonest. All of this happened after I handed over the money, and the engine problems started days later. Anyone in the area that has experience with Miatas, please let me know any information about what to do or where to take it.

I'm tired of working on cars, don't have the energy or time anymore and the Miata was just sitting and rotting because I didn't want to gently caress with it.

I also have a 96 Camry that is going to be sold as soon as I find a low mileage Mazda2. I just want a car i don't have to gently caress with for a awhile so I can do other things with my free time, spending weekends getting filthy underneath cars is not enjoyable for me anymore.

Like... Everything? How sure are you? Engine wiring especially. Small poo poo.

Not super up to snuff on MSM wiring, but doesn't pulling the ECU break a few circuits to sensors? The problem might not be ECU, but a gremlin further down the harness.

This could also be responsible for your poo poo performance. If the ECU is getting or giving whacked data because of a short, it will drive like rear end.

And even without a lit CEL there might be codes stored. Who knows they might have removed the bulb and its actually freaking out on you. Grab an obd2 reader, which might help troubleshooting any other dicked readings.

There's a fuse called "Room" that maintains power to the ECU when the car is off and it can cause the car to run strangely because it'll constantly be re-learning, and it'll reset any CEL's to boot. I ended up shorting mine replacing my antenna and it did a bunch of weird stuff. Make sure stuff like the dome light works when the car's off.

I worked on the car for about 5 hours tonight, checked the wiring and the intake for leaks. The car now starts but only if I put jumpers on the main relay. It still bogs down at about 4K rpm but I hear that's kinda typical. The relay tests ok but doesn't work when plugged in. A friend thinks the immobilizer may have something to do with it.

I am going to drive it this weekend to build up the data to get its smogged next week. I will probably take it to SB garage at some point to get it looked over. The engine is very clean but there is some suspicion that the engine may have been power washed or something and messed up something electrical.

I need to pick up the b5b4 relay from o'reilly and replace the jumpers. I tested with an obd ii sensor and there are no codes, so it seems like a weird problem that I hope doesn't keep occurring but seems like it might.

SC - Where there are more rednecks than people
So I'm thinking of selling my E46 M3 and putting some money in the miata (95M). I like autocross and i'd probably track the car every now and then. I don't really want turbo, because I loving hate turbo lag. So its either a super or an NA build. I have a buddy that has a VVT head he's looking to sell, so I figure i'd pick that up regardless. But would I really be able to do much on my low compression motor with a VVT head?

Anyway, what's the consensus out there?
1. NA, probably VVT head, full exhaust, flat top intake.
2. Super, probably MP63, maybe MP42.

Eventual plan is probably DIY revalved billsteins, 15x10s, race seats, harness, sway bars. Im not looking to go full race car, its going to keep the speakers and AC. Basically I made the mistake of driving a friends CSP car and it was a loving bucket of fun.

A VVT longblock (domestic or JDM) should run you about $1k if it comes with everything (manifolds, engine harness, body harness).

If you have an RB header, you're good to go. Sell the 2001+ header for at least $150 and grab a VICS manifold (net $0). With a MS3 and some dyno time, you're looking at 145whp/120ft-lbs easy.

If you're looking at just doing the head ($350ish?) and adding a supercharger, I would think that you'd be butting up against K24 money. I'd rather have the longblock if you're doing a VVT swap.

Hey everyone, got my Miata running but I had to bypass the main relay with cables to close the circuit. When the key is in the ignition, the relay does get 12v and is grounded, but won't start. The battery light and check engine light also don't appear unless I bridge that circuit. I don't understand it, but it seems like the ECU stops sending the signal as soon as I try to start the engine.

Otherwise driving the Miata is fun, the MSM issues are weird though and I want to address them as soon as I figure out this strange issue with starting.

I've been batting around the idea of getting a NC PRHT the past few months and selling/storing my NA because:

  • I have a gnarly back injury that will take months, years, or never to recover from and driving the NA for more than a quick errand hurts. I've tried foamectomy, adding foam, etc, and have also looked at new seats, but I'm already too tall for the car and everything aftermarket lifts me even higher.
  • It's safer
  • I could feasibly turn off the airbag, connect my kids carseat via LATCH and take him down the street to the store or the park (I live in a quiet, low traffic area).
  • I like the noise reduction, all weather flexibility and theft deterrence of the hardtop

I'm weighing that against the fact that the NC is probably 25% less fun than the NA in my limited experience with them.

I've been talking to this guy: https://wenatchee.craigslist.org/cto/5860289121.html and it's been fairly straight forward. He's been forward with the cars cosmetic flaws (bad mismatched touch up paint on rock chips, minor wheel rash, PDR opportunities) so I'm hoping I could talk him down a grand. I just got off the phone with Mazda and the car doesn't have Bilsteins or the LSD, which is kind of a bummer. I could always throw a FM kit on the car - is the LSD really essential to street enjoyment? I know I'd be missing out on the higher redline and improved shifter of the NC2, but a PRHT at this price point seems a fairly good value - especially within driving distance of me.

What do you think?

PS: He mentions a minor rattle from the engine bay that he hasn't figured out. He thought it might be a pulley but they were all fine. He had the dealership look at it, but they said it was normal to NCs and that he found other people with the issue online. Any info there?

Me have motors that scream to 10,000rpm. Me have more cars than Pick and Pull
Parents have had an NC1 and NB which I've put quite a few miles on, though the NC got converted to a race car.

The normal NC shock valving lets it down a little - too soft and takes too long to take a set. I haven't tried the off the shelf Bilsteins, but the race kit Bilsteins we put on was a night and day transformation. From what I'm reading the OEM Bilstein valving wasn't great on the NC1 anyway. The LSD is not essential unless you drive like an rear end in a top hat - poo poo, we didn't put one in until the second season as a race car. I personally like the trans better than the Mazda 5 speed in the Miata and RX-7s. And speaking as a big guy (6'3 and around 260 lbs) the NC somehow has more room than the NB. It doesn't seem like it should but it just does. The seat bolsters are kind of narrow if you're as wide as I am though.

I'd look at the Progress springs for the NC, and Bilstein Sports or HDs or Koni Sports - mild drop, mild rate increase, and Mazda specced it for a pretty limited run option package so it's pretty mild. That should fix most of the compromises. I'd definitely do an NC again for a street car.

Thanks for the help guys. Car got smogged and registered and its all good. The car runs better buts it tough to sort out the MSM hesitation from an actual issue, but it runs well enough to rule out a problem with the ecu.

But it is interesting that I still have to jump the egi relay power because it opens the relay as soon as I try to start the car. It cranks but does not start, and no battery or CEL appear when trying to start without the cables jumping the terminals. I am taking it to the mazda dealership this week to get the immobilizer checked out, but definitely no codes from an obd reader or check engine light.

Sounds like a real accomplishment. I live in FL so no inspections here at all, I remember how much of a pain they were when I lived in NJ.

I got a 2004 NB a couple weeks ago and I love it, unfortunately it smells pretty bad - no doubt do to too much moisture inside. The floor mats were by far the worst - they reeked and had enough dust in them that I don't think they'd been vacuumed since the Bush administration. I had to beat on the driver's side mat with a tennis racket for ten solid minutes before the dust stopped flying. I used Turtle Wax carpet shampoo on the mats and it helped but even after using that, letting them dry, vacuuming them again and then letting them bake in direct sunlight for a couple hours they still smell pretty bad, although they don't reek as much as they did. I'm going to do the same thing to the carpet lining for the rest of the car but I'm worried the smell won't be eradicated. Is there anything else I can do?

You could try similar treatment to what you did with the mats. Pull it out and clean it multiple times, although that's going to be difficult since it's molded to the contour of the floor pan.

Maybe after cleaning try closing the car up with an ozone generator running inside for the better part of a week...?
