Hi there, not been on here for a while after getting very frustrated about downloading images which I couldn’t get to grips with (no computer skills whatsoever sadly).

im not sure if things are easier these days as the site has had a refresh since I last visited. I will find out shortly as I’m going to try and post an image of my car which Mazda UK awarded show n shine MX5 photo of the year. I got a goody bag but the most important bit is that my little car (Dino) got the recognition he deserves.

I‘m learning more about this special little car as the months go by but the story so far is that it’s only covered 32k miles and is totally original as it left the factory. I believe it’s a very early UK spec car with the SNC engine, glossy roof latches and single hole slam panel. It was serviced recently by my local specialist who said it was one of the best early cars he’d ever seen an immediately offered me cash (lots) to buy it. I refused but was pleased my hunch of a good car was correct and my snap decision to buy it was the right thing to do although I do own another nice mk1.

Anyway, it’s crunch time so let’s see if I can download the prize winning photo….

Nice images Michael and yes, so much easier to upload with a much bigger file size permitted.

I have to confess that the reference to a "SNC" engine has me baffled, as far as I was aware the 1.6 engines were all given the designation of B6ZE(RS) with power output of either 114bhp from 1994-1998 but 114bhp from 1990-1993.

The 1.8 engines had a designation of BP-ZE, from 1994-1995 the power output was 128bhp and from 1996-1997 it was up to 133bhp, I believe the rationale behind the detuned 1.6 B6ZE(RS) from 1994-1998 was to bolster the sales of the more powerful 1.8 engine which had a block approx 25mm (1") longer to accomodate the larger bore to make up the extra cubic capacity, apparently the 1.6 block just didn't have enough meat between the bores to take the extra bore size.

Hello again,

I’m a bit of a novice but understand that only early cars had snc and this can be identified by 4 holes on the crank pulley rather than the usual 8. They have a bit of a reputation for pulley wobble which is very difficult to fix and has wrecked many snc cars but fingers crossed mine appears to be fine. I’m also lead to believe (I think) that they use a lighter crank and are slightly quicker off the mark. Certainly mine is quicker up to 40mph than my later 1.8 at which point the newer car finds its legs and is faster after this point.

I agree with your conclusion about the later 1.6 detuned engine and the embarrassment of the 1.6 being as quick as the more expensive 1.8. Interestingly the tuning boys prefer the 1.6 for tuning, turbos and the like for reasons that baffle me.

What is nice to see is that these little cars seem to be much appreciated than they were when I bought my pair a couple of years ago. Lots and lots of magazine articles and YouTube videos including the MX5 Restorer which I’m hooked on.

Hello Mike and welcome back to 'life' :)

That is a fabulous looking Mk1 and I assume "SNC" refers to the earlier 'short-nose crankshaft' engine?

Lovely example of a Mk 1 you have there Michael. Hope my NC will be as good in another 10 years.
Thank you,

Superb looking car that. I was looking for a mk3 before I got the Mk1 bug. They are very sensitive to the right wheel and colour to make the most of the lines. I love the stone coloured leather that seems to be available with some colours.

Thank you,

Yes, short nose crank which apparently are the earliest cars. They can be trouble but so far so good with mine. I think it has a lighter crank which spins more freely. I make it sound like I know what I’m talking about sometimes! 🥴

Ah, yes the short nose crank, to be honest I've never seen it as an acronym hence my bewilderment 🤪 plus my knowledge of Mk1s is relatively limited but yes, I should have got that one. The short nose crank has developed a bit of a reputation over time due to careless maintenance more than anything, they have a percieved rep for the key tearing up the keyway in the crank leading to all sorts of trouble but if in the event of the pulley having to be removed just take some extra care (or in reality just do the job right) and on re-assembly, just to be on the safe side, fir a new key and bolt and torque up correctly. My understanding is that damage to the key and keyway is often due to people being a bit hash bash. Clearly not going to be the case on your stunning example Michael.

Great work, Michael.
It is a beautiful car!
Thank you for posting the pictures (a skill I haven't learned in the new format).
