Just day-dreaming and wondering about the possibilities of fitting a Mazda MX3 1.8 DOHC 24v V6 into a Mazda MX5/Eunos. My main question is will it fit to the MX5 rear drive box?

don't think so mate, but the engine is virtually the same as the probe 2.5 v6, so if you get a rwd box, then fit the 2.5 instead  |

IIRC the Mazda MX5 box fits the other Mazda FWD 4 pots so its a question of if Mazda changed the bellhousing pattern between 4 & 6 pot models.

I've sure I've seen pictures of an MX5 with a K series Mazda V6 engine fitted to it....may have even been on here somewhere. From memory I think it used an RX7 gearbox, possibly with an adapter plate (or possibly not!).
I've got the 2.0 V6 engine in my 'modern' 323F.....it's a powerfull and smooth engine with some really nice grunt up the top!

Cheers guys It's just a pipe dream at the moment anyway. Maybe just the stock MX5 1.6 or 1.8 then, certainly would be easier. |

its been done, same engine as used in the probe but obviously bigger capacity. (interestingly, Ford used the probe V6 de-stroked to 2.0l in their touring cars  ). I've seen a video on this very site with a bloke with a mazda v6 in an mx5. i think Frank (skamanfrank with the imp) made a thread about these engines and the link may have been in there |

If thats the case a 3.0 V6 from a mondeo ST220 shold squeeze in there too, now that would be fun.

And if a Mondeo V6 fits, what about a Noble twin-turbo'd version?!

I don't think the Mazda K series v6 does fit the Mazda gearbox. The Ford Duratec engine fits the gearboxes in the latest MX5s, so maybe you could use one of those with the ford engine in an earlier MX5.

not sure about the duratec versions but it is likely should be plenty of probe donors about now scrappage is in play, one went on ebay recently, with gearbox loom and ecu etc. for slightly more than £50. I VERY nearly bought it ;D |

If thats the case a 3.0 V6 from a mondeo ST220 shold squeeze in there too, now that would be fun. The ST220 engine isn't the same as the Probe engine though. The Mondeo uses the Duratec, which was developed originally by Porsche and then Ford, with a bit of help from Cosworth. And as said, the Probe uses the Mazda KL. The Noble is a turbocharged Duratec, so again not the same. |

1989 Peugeot 205. You know, the one that was parked in a ditch on the campsite at RRG'17... the glass is always full. but the ratio of air to water may vary. |

The 1.8 will do fine, but if a 2.5 was available at the time..........................................................
Just remember this is just a pipe dream!

which MX5 is this going into?
I'm keeping an eye on this thread!
The 5 NEEDS V6 noises, it is the only thing I'd change about it.

As stated it's a pipe dream for now but if I were to do it I'd put it into an early MX5/Eunos.

Is there much benefit from the standard MX-3 unit? Other than looking a bit nicer and sounding better? The few I've been have been very unimpressive. Foot down, nice noise, barely any perceptable increase in speed. Mind you I suppose most of the VR6 VAG swaps are done more for looks and noise that performance. Just my thoughts, maybe I've only ever experienced bad MX-3 V6?
