Good choise of engine
It's all sorted out how to do it as you say. Well almost making the road when walking away.
I was looking around to have some more info on this swap and I found some links of interest:
http://absurdflow.com/klde.html Quite tech and a lot of info on the V6.... and a swap into MX5/Miata
http://davidandjemma.com/mazda/KL.htm similar here with a tech engine info
http://www.stratifiedauto.com/index.php?main_page=product_info&products_id=209 Some engine management system
https://en.wikipedia.org/wiki/Miller_cycle Just a favourite system in respirator help to an engine
https://en.wikipedia.org/wiki/Mazda_K_engine Just a common knowledge about Mazda V6
I just have to lay back and see how your are doing the swap... I will follow it. Quite interesting stuff
I did see that your KLDE V6 is able to do 7000 - 7500rpm but the KLZE is not doing more then 6000 rpm, new info to me and therefore you are closer to
the rotary thing in the 9000 rpm range.
But at last the 5 speed box do have a failure inside, there are some plastic knobs that is best to swap to aluminium. the plastic junk will break but
not the alu, and then you are loosing gears.
All the best

Both the KLDE and KLZE are safe to 8000 - the limiting things are the stock inlet manifold , and the ECU . Swapping to ITB's and a standalone
ECU will get you over 200 BHP , and lose a lot of weight .
I've wondered a bit about the KL into an RX8 - I would be interested to look at an adapter to fit the KL to the RX gearbox if they was going to
be enough interest . Also , as I understand it , the RX8 has a subframe similar to the Mx5 - maybe a tubular one could be done to make more engine
room - if needed ?
Its cuz I is blond , innit

Hey,
Good to hear from you! 
I had some more measuring and it's going to be close, the mods would be moving the clutch master cylinder which I'm not interested in
doing and the crank pulley. I have ideas how to over come these but don't really want to. 
I have another RX8 that I'm putting a new engine in to sell, it's a bit of work I have on the side to make a bit of money.
I drive them after I fit the new engine and clutch ect, I really like the driver feedback, it is a nice car to drive.
I know I'll have issues with the dash but Im not to bothered, I'll drive it with fuses pulled till I can sort it.
When I have the engine out for a rebuild I'll just lower the V6 in without the crap manifold and pipework around the back of the engine but
leave the auxillaries on just to see what fits. the subframe is forward of the crank pulley so there's issues with sump clearance but I think
I'll mod it anyway if it will gain me some room for a deeper airbox.
I was going to tackle to adapter plate myself but I don't have a mill.
Would you be interested in making one? Would you need my gearbox?

The pipework on the back of the engine is the thermostat housing and heater take-off - I leave it all in place since its not easy to modify !
I would like to have a look at doing an adapter - I could do it from either a gearbox or engine block .

Sorry, I meant vacuum and fuel lines. Just clean at the back of the engine as it will be close to the bulkhead, the split line is considerably further
back than most cars.

Once you go to ITBs, all the vacuum and fuel lines disappear anyway, so that should save you a good bit of bother. Although whilst the stock inlet
isn't great for power, it is low.
This gives an indication of how high my ITBs are next to the stock plug leads as viewed from the back of the engine. I do intend to machine them a bit
shorter but also fit trumpets to them so I'm expecting to need some form of bonnet bulge on my car, a '69 Sprite.
And should you be having issues with the crank pulley, the later 626 pulley has both a smaller diameter outer section, and a 32-1 trigger wheel on it.
You may have to ship one in from the States though, as I've not yet found new ones in the UK.

One thing to note is that the fuel rails will be quite a bit higher than the top of the throttle bodies - although I have got a couple of sets of
Pico-type short injectors which lower them substantially .
I have also done some much shorter trumpets - we dyno'd these on a similar setup to mine (in another V6 Mx5) and it made more power than mine
(but mine is suffering a bit of a miss-fire....)

Claire,
When you say more power, can you remember what it made? Or better yet, post the graph up?

I had a go at seeing how close the KLDE would go in the RX8, not very far, the sump hit the subframe, it was just a quick one to see what the major
issues were.
I buy the RX8 cheap to sell on with a rebuilt engine, while I had the last one I used it for a mock up.

I rework the sump to fit in the Mx5 - with the engine north/south the stock sump is a front bowl , so I just cut it all off and build one that works
!
This is how it sits in my Mx5

Donner Car
Hi all.
So I've bought a doner car that will be my commuter. It has a sunroof and satnav which I wanted so work will commence soon!

Ok, now the work has started, I have a spare car, engine and gearbox to do the mock up work on. I've made a temporary adapter plate while Claire
makes mine out 20mm ally.
The block goes in but I still have to cut a bit out of the bulkhead, the most important thing is that the crank pulley and lower part of the engine
clears my subframe and chunky steering rack.
This will be a quick mod, I'm going for simplicity and keeping many parts standard so if someone else wants to copy it, its not going to break
the bank and not a huge project. I need this finished this year so I'm aiming to be done in 3 months.

The gearbox to engine adapter is now finished - so a couple of photos !
The lightened Rx8 flywheel is sitting on a custom spacer , so it will use a stock Rx8 clutch and starter - cant wait to see some more progress !
PS - I have the distributer blanking plug sat here ready.............

Ok,
Have a look..
This car was scrap so I could use it to learn from and not be too bothered about damaging or cutting too much, templates were made after..

Here's the first look at my inlet set up, I'm using the standard injectors as they sit very low, cut the old manifold, lots of machining
and welding. I've got lots of good practice in! The linkage should be done in a couple of weeks so I'll upload another photo.

I had an RX8 for a couple of months and then sold having seen all the horror stories with the engines. Car was slow yet never achieved above 19mpg on
motorway and guzzled just as much oil. Next owner ended up paying for an engine rebuild a few months down the line.
Lovely looking cars though and a strong engine would be brilliant in one!

Hi,
I've been so busy with the project I forget about updating this thread. I'd say I'm about 80% done. In a few days I hope to be doing
the last job, the wiring loom!!!! That's straight forward. That's if I get about 15 to 20 hours in garage to finish off the single wiper
mount and airbox tray.
