OK, this all sounds pretty darn cool, but I have a question for the brain trust: True or False-miata transmissions are a bell housing away from fitting behind rotaries? What I am getting at is if adaptable to a miata trans, could this also be a sweet setup for all those second gen Rx-7s I keep seeing on CL for cheap?
In reply to wheelsmithy:
Need the power plant frame mounts hence the use of the Miata trans.Probably a way around it by using one of the V8 roadsters rear end mount kits etc but then the bucks down swap starts going out the window.
As a guy with a track only SC Miata I'm quite interested in seeing how this plays out,boost regardless of how its generated just adds so much heat/weight/complexity and potencial for problems going to a stock V6 Honda to get a reasonable power level sounds pretty attractive.
I may as well chime in here. My V6 swap (Mazda KL 2.5l) fits under the factory (92) hood, uses the factory subframe (one new motor mount though for starter clearance), and I'm currently running a factory 3.90 torsen with a ford T5 trans. The miata PPF bolts to the T5's cross member, which bolts to slightly modified FM subframe rails. It works quite well and gives me decent adjustment on pinion angle, and saved me a few grand on the swap.
My point being that running the factory rear isn't that difficult in these swaps if you decide to switch the trans, and modifying the Honda V6 intake hopefully won't be difficult either. Or milling a new intake from a chunk of aluminum is another option for relatively little compared to the total costs of a swap.
While I have never driven a V8 miata, I think a rev happy responsive ~250rwhp NA would be near perfect and of course V6 exhaust notes can be 'joyful'. Then again, you can always boost the V6. I've worked my way up to 12psi at the moment and it's...interesting.

It sounds as if donor availability would be the biggest problem, which is legitimate. Any recollection of available ground clearance or required changes to the steering rack or suspension pickup locations? It's the stuff you can't see with the hood open that's often the hard stuff.
Sorry, went on vacation.
I don't recall any clearence problems in the car at all. There was some fit issue with the shifter, since the access was quite different, but other than that, I recall it being a pretty easy drop in.
My memory could be pretty bad, though- that was a decade ago.
Great idea for a Lincoln, but not a great idea for a swap. Just not enough availability.
(I also don't recall that that the Miata rear was a big deal- I drove it back to Dearborn after the show and was very impressed by how plesent it was to drive. One of two "woulda, coulda, shoulda" RWD cars that I knew of that were Mazdas powered by Ford and could have been awesome Mercury or Lincoln products.... )
http://www.superfastmiatas.com/ So this is the website for this swap? It kind of has me skeptical of how serious they are about bringing this to market.
In reply to MG Bryan:
I've contacted them and had a little back and forth,just finalizing production costs now before releasing the information etc.

Good to hear! I'm dragging my feet on it a little bit, but planned to contact them as well. Their Honda swap Mini kits are really well sorted.
In reply to kevlarcorolla:
I drove one of the 2.4 Ecotec powered Miata's last week. That motor just looks like it belongs there. It looks stock, idles smooth, and runs great. Lot's of power, and loads of potential. They're in Richmond hill if you want to check it out, but you probably already know who they are.
Zomby - is there a forum for this swap? A company that makes the parts?
That looks simple and awesome.
I see a radiator that's about to explode the first time the car gets hot
Hard to tell how simple the swap is from here. It's an I4, so it fits in an engine bay that was designed for an I4. Reasonable enough. We can't see the hard stuff, like ground clearance, modified suspension and steering rack locations and transmission connection. It'll be a custom exhaust all the way back, and there's not a lot of extra room for the exhaust on the passenger's side due to the PPF, so that would be an interesting piece of packaging to check out.

Agreed, but that doesn't rule out a good turbo 4 cylinder - mine puts out similar torque at 1800-2000.
BTW, I love the sound of a KLDE DOHC V6 winding out (Mazda, Ford Probe). Those fit too. http://www.absurdflow.com/klde.html
The stock rad has been fine so far, for DD, lapping and track days at a fast pace. It's a very simple swap, with a few custom parts, which should be available soon. The exhaust looks to be very simple and straightforward.

I think this gets updated more frequently because it's simpler, and they're very busy.

He's not questioning the stock radiator, just that that one in particular is a ticking time bomb waiting to explode at the worst possible moment.
Exactly.
In reply to Zomby Woof:
Yep I just had Matt sort out my poorly running car,great service and price.
I'm sure that engine is the bees knees,but I REALLY like the idea of a shorter engine with no weight adding/heat producers/additional failure points to worry about on race days.I haven't looked to see if the Honda engine has any oiling issues with big g-loads,a Miata with lots of areo and long radius corners might find its weakness.I don't want to be the guy to find out so hopefully some other nut bars will build and track the hell outa this set-up 1st.
From what I've seen with these swapped into S2000's, here's no oiling issues to speak of.

I poked around and didn't come up with any that actually made it to the track,well one guy did a couple of test sessions than decided to start over with a boosted F22

They're swapping Ecotec motors into S2000's?
I am not a fan of Vaporware, and at this point that is all this is.
That said, the MGB crowd struggles with the V8 versus V6 question all the time.
It is Ginger versus Maryanne conundrum; we all know Maryanne is the sensible choice...however....
In reply to Xceler8x:
No, they're swapping Honda V6 engines from Odysseys and Accords into S2000s. We have two conversations going on here.

One was at Pikes Peak this year. The "S3700."

Thanks for the clarification. The Honda to Honda swap sounds a lot more appetizing. 
I hear you. I don't like it when steak juices get on my vegetables, either.
