I' guessing you're not running tires that big. That's about 12% over-sized!

I've either got 195/55R15s or 205/50R15s, either of which is pretty close to stock in diameter.

I'd be content with 30mpgs out of it. It's always come in around the 24 mark. Bigger, heavier wheels and tires probably don't help. She had other issues that I resolved already that would have been dragging down the fuel mileage. Hopefully they all add up...

Yea that's the size, 205/50R15. I'm running DZ102'S. When I bought the car everyone told me to get them, so I did. Even at 42psi I'm amazed how well they grab the pavement. I dodged a possum the other night at 60mph that I probably would have lost control had I been in the insight.

Looks like I have both! 195s on the front, 205s on the rear. Nothing-special brand.

Cool

Going back a bit...

I bought her on a whim however many years back (5+). She popped up on Used.ca (like Craigslist) for $1700. Guy I bought her from had, apparently, bought her with the intention of converting her to electric, but never got around to it. She had sat for a few months or maybe even a year. He was smarter than me and had taken the battery out, so a charge was all it needed before being put back in and she fired right up.

I took her around the block. She rode like she was on rails, and sounded great. Heck, I don't think I got around the block before I offered him $1300, cash, within the hour. He only took a moment to decide. A quick run to the bank and back and she was mine.

Originally, she appears to have been a no-frills '91 with the 1.6l engine and only one option: power steering.

When I got her she had the following "upgrades" on her:

Stainless long-tube header.
"Racing" clutch.
15" aftermarket rims with winter tires (of all things).
Koni adjustable shocks.
Blaupunkt CD/MP3 stereo with matching speakers.
"Rat-trap" chrome roll-bar.
Coil-on-plug mod.
Aftermarket tail lights.
Matching removable hard top.

And the following downgrades:

Gutted cat.
Dented right rear corner.
Cracked rear bumper.

The doors were half black, which is debatable if it was an upgrade or a downgrade. The soft top was intact, though the rear window was rather hazy. The ding in the right rear and matching damaged bumper was apparently from the previous-previous wonder, some young "kid" who put it in a ditch. I assume he put the "go-fast" stuff on it, and he probably raced it. Or thought he did.

I still think she was a good deal, even with 280k+ kms on her. A bit of work and I could have flipped her for twice that. The hard top was the real deal-maker...they tend to sell for nearly as much around here as I paid for the car, and with my previous 'vert getting broken in to once too often, I wouldn't bring home one without it.

Things I did to her, starting with those right off the bat:
Replaced the bosh platinum(?) plugs with good old NGKs.
Installed drilled rotors and new pads (it needed new brakes anyway).
High-flow cat.
K&N air filter (it already had the sticker).
Repaired the dent and repainted the area.
Repained the "new" bumper cover and swapped it on. (Half blue, half black, to match the doors.)
Painted the front bumper to match.
Enjoyed driving her for a while.
Replaced the noisy winter tires. (with some used ones...I'm cheap!)
Installed a "cheap" stainless aftermarket muffler meant for a later model (beautiful tone!!).
Threw an aftermarket seat in it (not the best idea).
After a while...
Replaced wheel bearings (unnecessarily)
Replaced the rear diff (bearings were going/gone. Noisy!).
Put a new soft-top on her.
...and parked her a few months later. D'oh!

I've never thrown a lot of money at her. I do my own work, and shop for the best deals. I think the new soft-top or the used diff were the most expensive individual things I've done, at ~$150 Canadian each (about $6.25 US ). Brake rotors and pads were under $100 for all 4 corners. Tires cost almost as much to get mounted and balanced as I paid for the tires themselves. Probably all comes in at under $1k over the course of 3 or so years.

Of course, I've thrown a lot of hours of labour at her. So I've really got reason to be thrilled that she's running well again! It's finally paying off. Now I've got a good running Miata with all this new stuff on her... whee!

Today's min-projects: Degrease the windshield and repair the leaky washer fluid reservoir.

Nothing to show for the windshield. Just a build up of road oils and whatnot. Spray down with degreaser. Rub it in. Let it sit. Rinse it off. Duh-un.

Here's the crack in the washer reservoir, and the rust it's caused to the retaining clip:


It's the curved line above said clip. Looks almost like a casting ridge, but it's not.

I ground it down a bit, mainly to get to clean plastic for proper adhesion.

Then I filled it, with...with...my frickin' hot glue gun of all things!

Normally, I'd say that's a terrible idea. Stuff never adheres worth poop. Doesn't get in to the cracks and crevices well.

So I hit it with my mini butane torch and really melted the stuff, which helped it flow. Smoothed it out as a consequence. Probably got it hot enough to allow it to actually bond with the other plastic, assuming it can.



Not much to look at.

But look, no leak!



We'll see how it stands the test of time.

Ok, so it's not that thrilling. But now my washer reservoir holds more than half a litre. Yay?

To do list...

Definite:
Fix slow brake master cylinder leak. (have a new one already)
Clean up surface rust in trunk below the battery, repaint.
Fix leaks in trunk. (Located several today, as it was raining well)
Clamp down battery properly &/or get the right size battery in there.
Polish faded paint on hood and trunk lid.
Swap in LEDs for most bulbs. (already ordered)
Brighter/white DRL mod.
Track down driver side seat tracks and swap back original seat.
Repaint rusty wiper arms.
Re-do old(er) black on doors.
Adjust header wrap.
Fix old hole melted in intake snorkel from being too dang close to said super hot header.
Replace O2 sensor.
Install braided clutch hose. (sitting on a shelf)
Install new shifter boot (also sitting on a shelf)

Probable/Eventual/Possible:
Replace brake pads and/or swap in larger brakes. (which I already have)
Fix paint chips on hard top & on front bumper.
Go black on hood/trunk/windshield surround.
Put lights in the visor mounting holes.
Add header wrap farther down.
Adjust air flow meter.
Add some sound deadener.
Antenna delete.

Not likely, but fun to ponder:
Hybridize it. (that diff just sitting there is begging to have a motor hooked up to it)
Kubota diesel it. (gotta do something with that engine)
V6 it. (have the engine and an adapter plate already...)
Go pure electric.
Build a removable fastback for it. (this idea is probably the most promising)

Notice there's nothing too outlandish or difficult on the "Definite" list. As long as she keeps behaving, I'll keep plugging away at it. And probably come up with new ideas along the way.

Questions for my fellow Miata NA owners:

How is your Miata for road noise? With and without the hard top, if you have one?

How about exhaust noise? (not coming out the tail pipe, but through the exhaust?

How quickly does your Miata get up to full temp?

I have a 1.8, so mine might vary.

Road noise is awful in every Miata. But you can cut a loooot of road noise by stuffing a pillow, or some form or fluffy material in the cavities above the rear shock towers.

Not too loud.

It takes a good minute or two to get up to temp. I would say 1-3 miles depending on the outside temp.
