Well, that's the question. Any help would be appreciated.
Also, how does one go about retrofitting one?

I'm not certain but I'm sure someone who knows more will be along soon. As far as imports are concerned, I thought all of them had an LSD of sorts but most had a viscous-type ones which, as the miles rack up, tend to revert to working as open diffs. This doesn't happen with the cars that had torsen diffs - I think they were the later 1.8 cars (post 1995?). Not sure whether the 1.6 cars ever had them or not.

I don't know which UK cars had torsen diffs I'm afraid.

I know that Mk 2 1.8iS come with a torsen LSD as do the models that are based on it (e.g. 10th Anniversary Edition). Not sure if any of the other UKDM Mk 2s have the torsen diff?

The NC 2.0 litre sport does.

Edited to add: And therefore I presume that the NC2 2.0 sport also does.

Risotto in another similar thread said:
Which one you go for is a matter of personal choice really. All mine were Eunos Roadsters (the one sold to the Japanese market). The were all built on the same production lines and, aside from minor spec/trim differences, all markets around the world got the same car whether it was badged MX-5, Roadster, Miata, etc.

You've got a choice of two engine sizes, 1.6 & 1.8. They look very similar so check the VIN plate. 1.6 cars will begin NA6C, 1.8 cars begin with NA8C. Some UK 1.6 cars had as little as 90bhp but other (identical) cars from a different production year had a fair bit more. The Japanese cars were never fitted with the lower powered variant of the 1.6.

I haven't owned one for a while now but from memory the Japanese 1.8 models from 1995 onwards came with a Torsen LSD etc which UK cars never had. Earler Japanese cars had viscous diffs which tend to revert to opn diffs over time. There are other features like air con (which, while hardly essential, is handy for clearing the screen in winter).

Japanese shaken tests (like our MOTs) mean that general roadworthiness standards are often better than cars from the UK. Additionally, the bodywork is generally in better condition as the Japanese don't salt their roads. The average annual mileage seems lower in Japan too. While evidence of servicing rarely accompanies the cars on their journey over here, it doesn't mean they haven't been serviced. If the car's done over 100,000kms, check that there is a silver sticker at the front of the cam cover with a kilometre figure on it - this tells you when the cambelt was changed.

Common areas where problems can occur include:

Electric windows (prone to slowing or sticking)
Noisy tappets - for a few minutes after start up this is fine, if it continues, investigate further.
Dampness in the boot (often because the plastic rail that the base of the hood sits in has perished)
Hood damage - the area above the windows can develop cracks if the hood is old.
Air con - check that the revs rise when it's switched on and that the resulting air is nice and cold. Earlier cars were filled with R12 - not sure how easy this will be to re-fill now. Later cars had R134a which is still in use today.
Bodywork - check for rust around the wheel arches/sills. Check panel gaps and look for signs of respray work.

Usually the above are neither difficult nor expensive to rectify.

There were plenty of Japanese special editions to chose from - some, like the v-special had leather & wood if you like that sort of thing, others like the RS-Ltd had kevlar bucket seats and Bilstein suspension. The S-Special is a decent package that offers better suspension and a reasonable level of equipment.

I'm not trying to put you off UK cars, I just think that because of the excellent reliability of the MX-5, the main advantage of UK cars (service history) isn't as vital as it would be if we were talking about some handbuilt Italian V12.

Personally I'd get a post 1995 1.8 Eunos Roadster but whichever model you go for, you'll get a reliable, simple to maintain, fun, cheap, great handling car!

EDIT: You'll probably pay more insurance for an import but ringing around for quotes should reduce this to a negligible amount.

There's avery basic guide to the Japanese limeted editions here.

There's a similar thing for the UK special editions here

My standard (Courtesy of Risotto) response okay? smile The buying guides give more detail - but the text covers the viscous/non-viscous diff! HTH

Mrs Hammerheads previous MK2 1.8i Icon (2000) had one. And the NC.5 2.0 litres get them too (except the autos).

Thread resurrection here (but I have been using the search function!) however does anyone know if all mk2 imports came with a torsen lsd or if it was only some models?

All Mk2 JDM 1.8s have a TorsenII and a six speed transmission.

Thanks. Great news. Did any UK models, other than the 10AE, come with 6 speed?

There were two Icons, werent there? The Mk2 always seems to be overlooked in favour of the Mk2.5.

Anyone know the difference between the S and RS spec on the Mk2 JDM's?

Haha, should have expected that! Looked at the guide on MX5OC but they dont appear to have any differences other than the RS has 15" wheels and the S states 5 spoke alloys!

I believe it means Japanese Domestic Market (?), i.e. import.

So no UK mk1 1.8s had one then?

My wife has an auto Eunos and that has an open diff proving that not all Eunos's were LSD.
I have bought an LSD for my special I am building and hope it lasts well cos its an early one of unknown mileage.

Not all automatics do, but Id consider an auto to be beyond the scope of a general discussion on PH.

They had a Torsen for the first couple of model years oddly, so it appears to have been a cost cutting excercise.

I thought it was the other way around...

From above..

(I don't know though, and am very interested to find out on way or the other)
