Need to be careful comparing the figures though.

Goodwin = Wheel horsepower
BBR = Flywheel horsepower

So not directly comparable......
While indications are that the ND has a remarkably efficient drivetrtain you are still looking at reducing the BBR figure by ~10% to make the numbers comparable.

Also need to be careful comparing US dyno figures with OZ dyno figures.
US ones read approx 20-30hp higher than ours for the same thing..
eg stock NBs are 130hp on US dynos, but around 100hp on ours.

Speaking of making ND's fast... I've been eyeing out diff ratios. Seems there's about 3 different ratios around depending on what size engine and what gearbox.

1.5 manual - 2.866
1.5 auto - 4.100
2.0 manual - 2.866
2.0 auto - 3.454

So if you opted for a 1.5 manual, find yourself a 2.0 auto diff for an instant increase in peppyness.
If you opted for a 2.0 auto, find yourself a 1.5 auto diff.
If you opted for a 1.5 auto, I wish you the best of luck with your mistake.

Installing the diff is harder than the old 2hr job on an NA or NB. The ND's rear subframe needs to be dropped.

Nice find. Are the autos lsd in Oz or would you source from OS?

No lsd on autos here

Well I guess you could swap the lsd centre in if interchangeable.

It turns out that you are at less risk as a pedestrian if hit by an ND.

I have now done about 800klm in my 1.5 ND Roadster including a club run in South Gippsland yesterday.As someone who wasn't that keen on the ND I thought i would share some impressions.Car has just over 2000 klms on and is being run stock.

+++++
great economy,5.1 on the 200 klm run to the start yesterday,6.0 overall including some spirited driving in the hills;

Best seats in any Mx5 i have sat in,really comfortable in over 8 hours use.

Gearbox is NA good,never any baulking in the shift pattern and beautiful action.

Goes better than you have any right to expect , no troubl e keeping up with the pack(maybe the 79RWKW I got on the dyno last week works in practice) Typical NA6 on the same dyno is around 64-67 RWKW.Gearing not as big an issues as i thought,dyno figures suggest that what torque there is available fron around 2800 rpm even though peak is at 4800.Power siniliar as good from 3000 on even though peak is at 7000.

Handles really well and feels lighter and more communicative than the NB and NC's I have dríven.Didn't notice the initial "lean then settle)" that i thought was there on my test drive.Perhaps just got used to it.

Exhaust is quiet but quite sporty.

Car is quiet at cruise.

Bluetooth is good.

---------
Steering wheel is horrible,too thin, too hard, too slippery,had to wear gloves!!

Storage space in cabin is not good.

Design attracts crap down the side of the car even in drizzle, far more than any other MX.

Not sure about performance of the standard Yoko's,will reserve judgement on that( Had a set of 17's fitted up with Michelin Pilot Sports but they wrongly fitted 205/40/17 instead of 45's!!! So standard set up for now.)

Door pulls are really small,not easy to use.

Still not sure about some of the styling elememts and thefront treatment,may age quickly.

OVERALL Very pleasantly surprised and think that any NA owner would love the feel and performance of this car.swapped with a mate in a beautiful low klms NB8B with Bilstein pss9's and a good exhaust and it felt big and heavy.He was surprised by the performance and handling of the ND.

Peter.

I hate the seats, I am always 'shifting' trying to find a comfortable position.
Perhaps its because theres -10mm headroom.... I'm probably wearing a hole in the soft top.

I agree. The wheel isn't 'bad', but it does have a slippery feel.
Storage is bad for a car, but i think it is 'normal' for an MX5.

Does anyone have a copy of the owners manual?

I found a LHD version, but wanted the RHD version.

Cheers,
Alan

Cheers Beavis, much appreciated.

One other observation.While the car goes much better than I expected i still think that an indicated 130 klph at 7000 rpm(peak power) in third is a bit over the top!

If I bought one of these I'm sure I would miss the rattle and squeaks of the NA and the clarity of my radio (when stationary).

Peter.

Almost the same as the NB8B was.... (128kmh @7000)
