Try miata.net. They have a section on the forum just for engine swap topics - if it's been done or can be done then it'll be on there!

pretty sure the v6 is not mazda influenced. try practical performance car magazines forum, it's been discussed on there (think one of the guys on there was a jag engineer, and the duratec v6 is used in jags as well)

is there a morgan forum? they use it too

I believe the Ford Duratec engine family were based Mazda engines...

However... reading Miata.net it seems there are too many problems with trying to fit the Duratec V6 engines (2.3, 2.5, 3.0) into an MX-5. A few have had a good look into it but have given up as a hopeless cause and switched to the Mazda KL engines series instead.

It seems we are all right. The V6 Duratec is a Ford design whereas the 4cyl Duratec is a Mazda design...

I think the more suitable might be a KL-ZE V6 which is a pure Mazda design and a narrow angle V6 to boot (more space on the side).

I did see a website with a fellow doing this exact conversion. I'll have a hunt around for you.

Did you look at the links I posted? Particularly the Cardomain one. The guy did a lot of research including designing a cnc machines adapter plate but thereare just too many issues involved with making it work to make it a viable option.

from what i've read (on the 'net so it must be true lol) the v6 had porsche input, the alloy blocked zetec se (also called sigma, also used in caterhams) had yamaha design and the four cylinder duratec (i4- not to be confused with the previous 2.0 and 2.3 four cylinder ford range also called i4!!!) is indeed a mazda. i think this is the one in the mk3 mx5

phew!!!

thanks lazza I did look I have picked up a few helpfull tips about how to mount the engine

if the v6 has the same belhouseing patten as a 2 liter duratec a behouseing from cat would work just need to find out what fits what and get a plate made up / make a plate up

i wondered if it would fit a ford mt75, as it fits the mtX75 which i've heard is a transverse version of the mt?

I as you state the mtx 75 is a version of the mt but they are from diffent eres i have seen only clasic (used in the looses terms )ford engines on mt's eg yb ,essex V6 and the old I4 (89>) but never seen a duratec on a mt before only one way to find out is to try it I will give it a go and get back to you on that
