You are better off buying good internals than swapping
Yup, and it should be the best one to use, as it had the lowest compression of those available (9.3:1 (Sportage version) v. 10.1:1 and higher).
I don't know if I can agree that simply going forged on the FS-DE is a better route. There's so much more that goes into making power. If you think about it, the FE3 made 170hp n/a, the same hp that the FS-DE makes with ~6psi.
The FS-DZE Japanese version of our FS-DE makes 180hp n/a, this is due to more aggresively tuned ECU and more aggresive camshafts, slightly higher compression. They also leave the factory with stronger connecting rods than the regular FS-DE engine.
As for the reliability issue of our Block, there really is none. The 'Rod ratio' and lubrication systems are the weak link.
As for the seeming 300hp limit?? Well this is a product of most persons choosing to use a turbo with a 350hp (flywheel) limit. aka GT28R and Gt28rs. However the turbo is selected in keeping with the gearboxes power limit.(300hp)(RTM)
the FSDZE or FS-ZE engines are a dream among tuners
everyone wants one and there has been a few who have actually gotten it but they fail at making it work.
so much money for nothing is not worth it.
going back to the FE3...so at a ratio of 9.3:1, what horsepower did it come with?

At 9.2:1 it was doing 130hp 127tq on 87 octane. With compression increased to 10:1 and a half decent tune, it should be at 170+ n/a.
If I remember correctly, the rods are forged already. Please double check that. You can increase compression with thinner head gasket, new pistons, etc. But you probably know more about that than I do. As you pointed out, the Sportage motor should be a LOT easier + dirt cheap to obtain. Bump up the compression just a tad, tune it for 93 octane, and you've got AT LEAST 170-180hp n/a. If you get either the JDM FE3 cams or a set ground to the same specs, you're looking at over 200hp n/a. Pop a decent turbo on there and you'll hit a reliable 300hp quite easily.
Corksport should be able to help you with this if you decide to do it. Hell, if you lived closer I'd help you just for the pure enjoyment of the project.
this website has an awesome reel of information.
a very good read indeed to learn about mazda's engines specially the FE3 and miata engines.

Best advice. After reading about the FE3, I'm not impressed. Cast crank vs. forged on the FS. Similar compression and power numbers.
Turboing the JDM of either engine is a bad idea.
Are we going for unique or big numbers? The FE doesn't sound like either.
I would like to know what is a good head setup to run with a FE motor with forged intrenal. Port port, polish, cams, and etc. I am looking at taking my stock MSP block with forged internals and run a CR from 8.5:1 to 8:1. I would like to run a Haltech but still thinking about the head setup.
you might be a little confused.
the FE motor is a different platform than the FS.
there are no interchangeable parts between the motors.
one came in the miata and earlier proteges the other came in the probes, mx-6's and late generation proteges.

Alejo, a BPT swap is very doable. As stated before , you need to fabricate a bracket for the rear motor mount. The side ones can be made to fit with a variety of parts ( i.e. get motor mounts from 1st gen protege, 3rg gen 2.0L as well as 3rd gen 1.6 )
For the transmission you can use your old one but you need to find a bellhousing such as one from a Protege or Escort GT that had the G series trans. Everything else would work.
Does your car have ABS ?
