I'll be watching this one with interest. I bought a Mk1 last year which I've been tinkering with since.

Had a look at the Rocketeer cars at the national meet in Gaydon back in September. Awesome bit of kit.

I plan to add a bit of power to mine in the near future but will likely go the usual turbo route.

Oh and I'll see your rust and raise you this...

From a glance at the pics, I can't imagine this minor issue has been resolved. Saying that, general access looks good, and that it'll take literally about 5 mins to remove those manifolds..

I've been thinking recently that I really need a project. Having had a couple of Mk1 MX-5s in the past my thoughts have been homing in just such a project. I have done zero research yet, but am definitely interested in the idea of an engine transplant, so I will be reading your progress with interest. If you're happy to share outline costs then that would be interesting and helpful also.
The kit is basically £7k, and to that you need a base car (and mk1's seem to be going up in value quite quickly) and an engine. Rocketeer can provide a crate engine I believe, but I will probably be trying to get one out of a wrecked Jag S-type. As the gearbox is not needed from the Jag, you can take the engine from an auto as someone has mentioned on this thread. They seem to go from between £300-500.

There are then a few bits you need to get hold of, like a second mazda 1.8 throttle body.

I have started a spreadsheet to track costs - to be honest I think it will be quite pricey, but then I'm keeping track of tools bought as well. My new impact wrench is my new favourite thing. A total lifesaver!

Wow, that puts it in perspective!

Watching with interest!

A long term dream would be to make a west-dax-field out of an old S-type, but this is still in the serious dream stage at the moment. Junior PG has moved the dream back a fair bit, now I dream about making baby beds...

No doubt you have seen it, but http://www.alfadax.com/ is a PHer, Crusty Crammers I believe, he has a really nice build blog.

The more updates the better! - no matter how small!

So if you don't get a car or the engine for £7k, what do you get? Some brackets?

You call that rust?

Is there a weight penalty with the Jag engine? Jag V6 seems a strange choice.
Um yeah where is the rust there? As far as old cars go I can see pretty much zero rust, apart from a little bit of surface corrosion.
I'm glad I wasn't the only one who thought that! Looks like it's had some sort of wax treatment at some point. My 2006 NC has much more surface corrosion.
Same here, was expecting the car to be missing!

great build OP will sound the nuts and go like stink, one thing if you already have the car and the engine is 7k not a bit much for the conversion kit?

It's been fixed now, major rustectomy with lots of new metal welded in.

Looking at their website - bespoke brackets and mount are £2k. £7k includes everything else:- electronics, exhaust system and all the ancillaries.

Another watching with keen interest. We currently have a one owner 3.0 V6 Jag S Type, it was my uncle's and has only done 20k miles. Sadly the whole car seems to only be worth >£1k!

What do they do with the gearbox?

It’s not cheap, but then you’re also paying r&d costs, plus a profit for them. Of course some will think it’s not worth it - fair enough.

Having driven it, and not having the skills to do that kind of conversion myself from scratch, to me it’s worth it.

I do recommend viewing their website though for more details, plus photos etc. It gives you a better idea of what’s on offer.

I think I'd be seriously interested in a V6 conversion into a MEV Replicar. I wonder how feasible that would be?

OP - loving the idea. Will follow with interest.

For an MX5, that is far, far from rusty.

Interesting project though, good luck!

I see it has two throttle bodies and they're fairly far apart, the MX5 uses a cable throttle so how does the nearside throttle operate?

Bookmarked and will follow closely.

I had no idea such a conversion existed until a few minutes ago.

I think even if you did happen to stumble upon a freakishly clean MK1 you'd still want to do a fair amount of preventative work under there to protect your investment. Putting all that time and money into the car only to then be afraid of getting it wet or dirty would be a terrible waste. Properly sealing and protecting the underside will pay off many times over in terms of durability, peace of mind, and ultimately your enjoyment of the finished product.

I have to say, I'm not sure. Whatever method, it seems to work! I'm guessing a second slave cable, but I'll let you know when I get it.

That was the idea - no point spending on the conversion and fitting it to a rust bucket. Even though I do enjoy Roadkill on youtube...

That was my first thought, I quite like the Replicar.
I'd guess it could be easier as the MEV only uses the bare bones of the Mazda.
A big plus being you wouldn't need to worry about body rust on the MX5.
