ebay: MX5-based Cobra...
... "with no SVA/IVA"? Sounds too good to be true - can it really be just a rebody of the external panels, with no changes to the
monocoque?

It looks fairly clear that parts have been welded onto the monocoque.
If you can't unbolt and lift away the body and any subframes, leaving the monocoque as per the original design then it's off to IVA.
Nice looking project though - wonder if it's home built or a kit.

Was reading in CKC about a company who does a similar type of thing for a shportened Mondeo monocoque and no IVA for that either, which seems strange
as I understand no VIC or IVA if the mono has not been drastically altered or had anything taken away, so the MX5 conversion should be fine.

If it's shortened then it should go through IVA...

I also really like that.. but its one of those projects that will either be really well engineered and thought through, or, under that shiny body,
will be a mass of bodged scrap requiring expensive rebuilding to complete..
If I lived closer I would go look.. could make a really nice car....

If you chop away the outer,doesn't that lead you on the Banham type problems regarding SVA/IVA

I think the same applies for adding more to the chassis as well as taking bits away - I was looking into (and still am) building a Sammio Spyder and
they have similar issues. The way round it is to prove that any structure you add is only to hold the bodywork in place and if unbolted will lift
away leaving the original chassis intact.
The Sammio uses the Herald chassis, which isn't a monocoque like the MX5, so as soon as you replace anyting more than body panels on the Mazda,
you've altered the chassis and IVA is required.
That's my understanding of it, anyway (as much as I am ever likely to understand about the IVA pedantry )

The 'original chassis' of the MX5 consists of the subframes and the monocoque body. Now, if you take away the bodyshell and replace it
with another completely different one, even if the dimensions are exactly the same you are substantially altering the original chassis, there is no
getting away from that.
Absolutely no doubt this project needs an IVA.
.
Having said that, it is quite a bonny looking project - it is certainly much nicer than the Exocet which is a similar set up.
But, a Cobra replica MUST have a V8, surely?
All in my humble opinion, of course.
Luego Locost C20XE.

The seller make the comment on a V12 will fit,
In the states there are MX5 / Miata's with 5.0Liter Ford engines, thats a fair bit lighter than any V12, but the axle gets binned for a 8.8 Ford
axle
There is also the mention of the Engine in a different position.
Anyway it's cheap enough to compensate, for any problems
