Are there crossover vehicles that can tow a miata? That seems like the ideal.
I believe the Subaru Outback can tow at least 3000lb since 2005. There might be a towing kit upgrade as well, but I don't remember hearing of one. Try the turbo (XT) or 6-cylinder (H6, 3.0R) models, though the H6s are all automatics.

Other than that, I'd just look at a used truck (Ford Ranger, Chevy S-15, etc) or something based on a truck frame for an inexpensive tow vehicle.

Today I heard a rattle in my dashboard(?) and I can't figure out what exactly it is causing it. I think it's coming from the right side of the gauge hood, above the keys. Only rattles above 50mph-ish... difficult to inspect it at that speed... Anyone ever have this before wanna tell me what it was so I don't kill myself trying to find it?
I don't know if you've solved this yet. Do Miatas have any heat shields in the engine bay? A loose heat shield has been the cause every time I've had a weird rattle in a car at high speed.

Finally did my 100 mile commute in the miata today for the first time, really the first time I've driven the car outside of the bronx to brooklyn when I picked it up. Here are some weird things I noticed.

One, it sounds like a school bus. In fourth and fifth gear especially, while either accelerating or decelerating in gear, it makes a sound like a school bus, that's the best I can describe it. If I hold the gas perfectly steady it goes away, but as soon as i accelerate or take my foot off the gas to decelerate it comes back. Seems to be the most noticeable at lower RPMs.
By school bus, do you mean a "grunch, grunch, gruuuuu" sound like when you're grinding between gears but kind of softer? Poorly sound-insulated transmissions generally sound like this when you're decelerating; my WRX box sounds like this all the time and my J-body was like that in second gear. It might indicate that your synchros are going or your gear oil is old.

VE is volumetric efficiency.

Check out volumetric efficiency 101. VE and airflow are directly related. When you're setting up the map on the ECU, you define a table that illustrates what air/fuel ratio to target for the given amount of airflow.

MAF in this case refers to the mass-airflow sensor; it emits a voltage depending on how much air it senses going past the sensor, which is used to compute the current VE, which is used to look up into the table to figure out how much fuel to throw in to try and get the best air/fuel ratio.

You probably don't have to worry about adjusting the tune for your exhaust and intake. You could always tune it to try and get the most out of your modifications but I don't believe it will impact reliability. The only thing I'd be worried about with a cold air intake is (I assume - I haven't seen this particular CAI) the increased potential for hydrolocking after deleting the stock 'snorkel' off the intake plumbing.

Baby Hitler's point is that the computer is only designed to see "so much" air; if you increase the flow much past the maximums that are programmed into the tune (and/or the voltage range of the MAF sensor), it just won't do anything with that extra air so you won't see a gain. In this case, I think what you are supposed to do is replace/augment your MAF sensor with a "wideband sensor" and then reprogram your entire tune to take advantage of the additional air you now have available. However, you probably don't need to do that if all you're doing is uncorking an intake.

edit: Something else about volumetric efficiency.

Only the driver's side is like that in my '97 Impreza (then again, it has power locks). The passenger side will gleefully lock you out.

Both doors are like that on my buddy's '87 RX-7, so I can definitely see that it was a groupthink thing.

I'm having a lot of trouble finding a decently priced NA Miata, since I want to start putting one together to be ready for when time attack and lap days return to my city in ~2 years.

In my local market (Calgary, Canada) NAs pretty much start at $4000 for a high mileage 1992 and quickly go up to $8000 for a 1995. Most of them are garage kept (out of necessity) but lots of them have rust developing because people never took care of them besides shoving them inside occasionally. I don't think these people would be receptive at all to me asking a significantly lower price. I'd like to pay around half that, and get a 1.8L (post-94) with a nice body that isn't hugely cancerous.

For Subarus, it makes sense to buy during the summer when people get tired of the fuel mileage, and it makes sense to sell them during the fall/winter when people usually have their first inattention-to-driving snow accidents. However, Miatas are never listed during the winter, because nobody "normal" wants to think about buying one and driving it home in the snow.

When I look at American Craigslist (Seattle, San Luis Obispo, SF Bay) I find slightly better prices, but there still seems to be a lot of overpricing of the car by "normal" people who just consider it to be a sports car and therefore inherently valuable. There are also a ton of automatics, rice rockets, non-runners and salvage titles in the US market. By the time I start filtering out those ones I'm up to the $3500 range which doesn't justify the plane ticket down and time off work to bring it back.

Is the trick for me just going to be camping out enthusiast forums (Miata.net, ClubRoadster is where I've been looking so far), waiting until someone gets massively in debt and has to unload their project and then getting on a plane, or is there another source of cheap Miatas I've ignored?

Is this just the reality of Miata purchasing, that pretty much everyone is an idiot who's gotten emotionally attached to their car and thinks it never depreciates?

I finally bought a Miata!

Picked up a '91 with hardtop and a ton of spares:
  • 94 transmission
  • Torsen diff
  • Open diff with the right R&P for the final drive
  • 949 racing wheels (plating is coming off) with RS3s
  • Escort GT wheels with studded KW22 winter tires
  • Stock 99 wheels with.. some kind of tire, I forget
  • Loose tires
  • 2 spare tires
  • Kirkey Racing aluminum seat
  • 2 soft tops (original and glass/defroster)
  • Spare steering rack (manual)
  • Axles for the Torsen
  • Racing beat 1.25" FSB
  • Carbotech XP8s
  • Bilstein PSS9s

I'll have some pictures. Anathema though it may be I'm tempted to see if I can repower the depowered stock steering rack and maybe even quiet the custom exhaust down a bit.

Pretty good deal. Now I need to get rid of everything I don't want.

So my '91 has a few problems so far:
  • Oil pressure gauge seems to always report maximum pressure. Broken sender, bad wiring, or stuck gauge? Leaning towards the latter, as it's always at maximum even when the car is off.
  • Missing the rear hardtop latches (on the B-pillar, not the ones that hold the butt of the roof on)
  • The "doors" mode on the glovebox light doesn't seem to work for drivers' side. Dead door sensor?
  • The ignition cylinder is hard to get the key out of. When I turn it to OFF I have to turn it back to ACC/ON, then push it into the cylinder and turn it. Sometimes I have to wiggle it a bit, and it's not smooth like I figure it should be. Is the key to blame (the door locks also don't seem to like it) or is the cylinder just so old that I should look at replacing it?
The manual mirrors also seem to be pretty stuck and I'm afraid of breaking them. I remember seeing a guide in Practical Classics (or was it GRM?) on how to fix it, so I'll refer to that and see if I can make it a little more comfortable for me to drive.

I giggled for probably five minutes upon finding out the flip-up headlights make a little light illuminate on the dashboard to tell you they're in the process of flipping.

It also has a super loud custom exhaust. What options do I have for quieter aftermarket pieces? I saw the Racing Beat Power Pulse but admittedly haven't done much research. I'm leaning towards getting a used factory take-off and reinstalling it.

Seat Safety Switch: For the key, does wiggling the steering wheel help? Or does it seem like it's the cylinder itself hanging onto the key and not the column lock?
Feels like it's the cylinder dragging. It doesn't want to go 'in' very far when I push it.

The steering wheel is always straight ahead, but I'll try wiggling it a bit while I push and turn. Once it "catches" the cylinder action is very smooth, it's just getting over the safety push to remove the key.

It's not an OE Mazda key so maybe it was slightly miscut? Would explain why the doors don't seem to like it much either.

Unfortunately no original key. Oddly enough the key only turns the ignition one way - sometimes I have to flip it over to start the car.

I thought it was maybe a quirk but now that I think about it almost all car keys should be symmetrical.

Perhaps I'll stop by the dealership and see if they can cut me a new key from the VIN?

It looks like I'll be picking up a Miata in the next few months, more likely next week. How difficult is it to swap a Torsen LSD into a NA (1991 SE) car?

The car will eventually be built into a track rat working towards a full spec Miata build over the next few years. Or is this a horrible idea and I should just but a 1.8/torsen car to start with?
I'm looking at doing this right now - a '94 Torsen and '94 gearbox came as spares with my '91, along with what I assume to be an 89-93 99 open diff.

The owner said that I need to swap the ring and pinion over from the open diff to make the final drive on the 94 Torsen correct for the 91 gearbox (although google searching seems to indicate that the 91 ring is much weaker and I should just live with the slower accelerating FD), then swap the axles, diff housing and driveshaft (the pumpkin is physically larger) for the 94 parts. I admittedly haven't looked into it much, but I remember it showing up in the Project Car magazine Miata as well.

I was also planning on replacing the diff bushings while I have the new carrier on hand, but one thing at a time.

edit: Actually it just occurred to me that the spare open diff I have is probably out of a 99, which would give me the stronger ring and the better ratio.

I've got a bigger front bar on my NA. The previous owner's rationalization was that it reduced rear wheel lift under aggressive cornering. A few S2000 autocrossers do the same thing.

I think it might be one of those driving style things. I'll have to drive the car pretty hard and see how it is - I like a lot more rear end-sliding but I am used to Subarus after all.

My first startup it stalled out even though I had it in neutral with the clutch in, second startup it fired to life on the first crank and returned to idle just fine. :iiam: Oil pressure gauge goes to 0 when I turn the car off now, but is otherwise above maximum even when the engine is cold.

That looks like someone was riding the clutch while the car is in motion (maybe a previous owner judging from the cracks/scratches on top of the bluing), but a TOB failure might make it happen too.

Hell, I can easily see the TOB itself wearing out faster under that kind of abuse, and then your poor mom was left holding the bag when it went out. Must be a lot nicer with a fresh clutch in there.

I wasn't aware that it was really something you could install on an existing part easily. Do they make threaded ones - I imagine you drill and tap a hole into the bushing mounting area of the hard part?

How do you get the old grease out? Most of the poly bushings on my WRX are loose enough that I guess you could just blow the old stuff out by injecting a ton of new stuff.

It's a good looking car (though it looks like it could do with a clay barring and a wax) but I don't think there's anything really special about it that justifies 5k in your local market.

I'm guessing it's not a street car as most street cars have not been professionally corner balanced, though maybe the average Miata owner is a little different. It must be interesting owning both a (baby) Hummer and an NA.
