Right, we don't know the full story. That's my point that it seemed to good to be true, but doesn't mean that it is. I'm looking for more info like everyone else.

i was researchign this and noticed a guy doing a swap of a renny engine into an mx5 and used the mx5 subframe to fit the renny without mordification now since the mx5 can be found with a 2L mzr engine i believe that the 2.3 L mzr will also be able to fit in the mx5 ( the difference between the 2 being a different crankshaft giving a longer stroke producing 2.3L ) so if the renny can fit in the mx5 the 2.3L mxr should be able to fit into the rx8 u will have to mordify the firewall and posiblly remove the cabin heater now the only thing i can see as a major proble is which gearbox to use the rx8 or the mx5 gearbox and the engines electronics that i have yet to figure out

You also posted something completely unrelated in a thread having nothing to do with a mzr fitting in an mx5... please make another thread..

It's even more amusing that after all these years you still think that your opinion influences me
I knew the dates when I replied, you do realize the thread was revived several posts ahead of mine? We could just as easily ask why it's still open. Yet it is so the stupidity continues. I'm game.

Other's perceived ideas are only stupidity if you happen to see it, but if it floats your boat to think that you 'are superior' then by all means be happy
(So many of your little sayings are ones that you could do well to apply to yourself, after all, isn't it just making you happy to offer the little zings you do?)

Oh we know you aren't superior. No misperceptions there. Your demonstrations of humility are exceedingly effective at ensuring that you want everyone to be aware of that fact.

maybe if u could actually read and read past the first line u would see what i was saying does relate to placing an mzr in an rx8 as it compares what the guy is doing and similarities between there sub-frames and how the mzr would be able to fit in the rx8 so if u forgot how to read im sure there are adult education classes somewhere in ur area where u can learn

The 2.3L MZR was only ever used with a transverse mounting.
The 2.0L in the 2006+ MX-5 was longitudinal mounted, and a varation on the transverse mounted 2.0L
There is a significant difference there that makes the "matching subframes" not really applicable any more when you start talking 2.3L MZR

The 2.3 and 2.5 MZRs swap into the MX5 with a little work. Here are the instructions:
2.5 swap instructions - MX-5 Miata Forum
The most important take-away is that the, "Motor mounts are direct bolt-ons, trans bolts up the same, [and the] exhaust manifold is the same." So you would just need the subframe from an mx5 and the other appropriate electrical equipment.
