I'm not sure where all these opinions come from that the Miata is a slow car. As stock, in the snow on street tyres, I ran a recorded 16.8 @ 81mph and a 0-60 time of 8.1 seconds, 17 years after my car was produced. Exactly what Mazda said my '91 1600cc would do all those years ago. While that's not exactly tarmac-shredding, to put it into context:
BMW 325 (E46) - 16.9 @ 82mph, 0-60 8.5 secs
BMW Z4 2.0L ('05) - 17.2 @ 79mph, 0-60 8.7secs
Lexus IS200 Sport - 17.4 @ 79mph, 0-60 9.05secs
Mercedes SLK200 - 17.1 @ 80mph, 0-60 8.7secs
Porsche 944 - 16.2 @ 84mph, 0-60 7.8secs
Alfa Romeo Brera - 16.6 @ 85mph, 0-60 8.25secs
Audi TT 150 - 17.5 @ 80mph, 0-60 9.06secs
Citroen Saxo VTS - 16.6 @ 83mph, 0-60 8.14secs
Now, as I said, none of these cars are what you might call 'fast' in a straight line. But to call them slow and/or underpowered is unfair. The Miata certainly never feels underpowered, and with the cars weighing in at around the tonne mark, ~120bhp is ample enough to propel the car in any given direction.
Besides, I came to this car after owning a Stage 2 Nissan 200SX RS13, which ran consistently mid/low 13 second quarter mile passes. On the Nurburgring, my BTG time dropped by over 3
minutes in my Miata. Now, my Miata is modified, though is still N/A, and power-wise is near enough stock. If I were to start again with my car and not have the trial/error period of buying parts that weren't much good to me, I could buy and build the same car for less than ?1500. On track, in it's current spec (without the cut-slicks) I've had the pleasure of 'beating' all kinds of exotic machinery, from 500bhp Evos and bike-engined single seaters in the UK round Croft, to 997 Porsche 911 GT2s, Ferrari F430 Scuderias and GSXR1000 bikes round the Nurburgring in Germany.
The point is, there's so much more to driving fast than having power. In a straight line, I would be raped by all the above machinery. The fact is, I learned the track more extensively than they did, the car is cheap enough that I'm prepared to push it more than they are, and the car inspires enough self-confidence that I can do all this without being remotely scared, and therefore able to concentrate on racing. It's taught me so much about driving I wouldn't know where to begin, and I can now control much more powerful cars with the same precision as I can my own.
In stark contrast, when my S13 was on the limit of adhesion, I used to become so scared I simply un-buckled my seat belt, climbed into the back seats and simple prayed to God that I wouldn't die in a horrific fireball. I even recall coming out of a roundabout in second gear, on new (but run in) Pirelli P-Zero Rosso tyres on the inside to overtake a car on the dual carriageway. My S13 pirhouetted around the 306 until I was sat 20m in front of them, in their lane, facing them. Luckily he avoided me and I wasn't killed. At that moment in time, I'd had the S13 for 7 months, I'd already been to the Nurburgring in it and done 3 trackdays in the UK, and I'd had a MK1 Toyota MR2 for 6 months previous to that.
Anyway, if you're interested in a Miata, I'll point out the differences between the models. Don't be confused by terms such as ''special edition!!!!''. Mazda made so many it's unbelievable, and the only one worth buying, the BBR, you guys didn't get. Often it as used instead of offering options. The S-Ltd, for example, had a red leather interior and only came in black. That's it.
Personally, I'd opt for a MK1. They're cheap, plentiful (so parts and spares are easy to come by), very reliable, and did I mention how cheap they are? They're also much more 'raw' to drive than the MK2. They're no faster, but they do feel more fun.
1989/90 - Mazda introduced the 1600cc MK1. The entire car is based on the Lotus Elan S1 chassis, and the engine puts out around 120bhp. In the UK at least, Mazda used a short-nose crank which in a decade would turn out to be problematic, though Eunos models never suffered. This is worth checking if you're in the US, as I'm unsure if they suffered too.
1990/91 - Mazda fit a long-nose crank instead, realising they may have made a potential future cock up, which proves very reliable.
1992/3 - Mazda introduce a 1.8L variant, with 130bhp, bigger brakes, extra chassis bracing and the optional extra of a Torsen LSD.
1994 - Nobodys buying the 1.8s, as far as people can see the extra money isn't justifiable for an extra 10bhp. Rightly so, though the 1.8Ls have an extra 10bhp, they have a lower final drive in the gearbox, meaning their performance is exactly the same. Mazda therefore drop the power of the 1.6s to 90bhp in order to sell more 1.8s.
Essentially, the cars really are bulletproof. The block is taken from the Mazda 323 GTX/R, which was a turbocharged engine in the first place. Essentially, this means all you need to add FI to the car is: Attach an oil return feed, a turbocharger (TD04 or T25), and a suitable exhaust manifold, and at 5PSI you'll have 160bhp without touching the injectors, ECU or fuel pump. Throw on some larger injectors from the MK2.5 (230cc) and increase the boost pressure to 7PSI, and you can easily hit 180bhp. Add a Link/Emerald/E-Manage and a larger fuel pump, plus Supra injectors (270cc) and you can easily be seeing 200-240bhp depending on the map, and if you buy used, you can do all this for less than ?600.
For me, the biggest differences have come in chassis upgrades, and I've temporarily abandoned the want of a turbo/supercharger because of how I've out-performed FI cars on more technical courses. Toyo R888s add ''50bhp'' in real world terms. That's not to say you can dyno the car and have gained an extra 50bhp. But, for fast driving, this one simple modification gave the same effect as an increase in 50bhp would have done, as confirmed by our clubs resident track racer who ran R888s while his supercharger was being fixed. Then, a decent set of springs/shockers (whether they're adjustable or not), and a Roll cage meant my car was cornering ridiculously well for a hairdressers car.
When buying one, check the sills for damage, and usual areas for rust. Some engines suffer from 'HLA clatter', this is nothing to worry about, and is just the cars way of telling you that the engine is due an oil change. It sounds very similar to 'timing rattle' or VVTi clatter, or tappets, but isn't.
I could go on and on, and would happily if you need the advice. To summise, if you're concerned about the image you'll portray to people, like some obviously are in this thread (though to throw stones in glass houses, a Legacy Wagon?
), then don't buy either. At 16, I doubt you have the chest hair or a medallion large enough to get away with driving a 300ZX. If you're after a serious performance car out of the box, buy the 300ZX and watch your money disappear in repair bills. If you're after some cheap, no thrills fun with the potential to hurt fast cars where it matters - on track, then buy a Miata.
