Nothing changed mechanically, its all the mapping in the ecu that changed between a regular protege, and a MSP.

If its tuned properly... For anything above 6psi, a FMU doesn't seem to cut it. You'll want a piggyback or standalone. The MSP has the benefit of an ECU that is prepared to take on boost. Stock Proteges don't.

I think that is possible, but it probably won't be "efficient" as they are not the same size turbo and such, but it would definitely be much closer and better than what you have. Yet that ECU won't be cheap. Might be able to make it though, since the speed runs rich as hell too. Very interesting. No one has tried it though, that I'm aware of. (Mp3Moran or something like that was going to try it way back when, but I think he gave up on it ALL.)
And on a side note, I heard from a good source that the speed may have gotten forged rods and that was the reason they were "late" getting to the dealership. I don't think any of the speeds have replaced rods yet, so until one does we won't know for sure!

I've heard from some reliable sources that the rods were changed at the port. The MSP had a difficult birth and I don't think it's a coincidence that the Mazdaspeed Miata is a factory car instead of a Callaway one.
As for putting an MSP ECU into a "normal" Protege - go for it. It's certainly worth a shot. With the recent reflash, the software is in the system so this should be possible with a cooperative dealer. You'll probably still need to do something to deliver more fuel given the larger turbo, but you'll be closer than you were.
FMU is a Vortech name. It's probably the least descriptive name I've ever heard because it's so generic. It's a rising rate fuel pressure regulator.

Hmmm, maybe I need to get a hold of a parts guy at an MS delaership and ask about part numbers for both cars.
The differnet part numbers would be proof something changed, right?

Assuming the parts made it into circulation, yes. The 323 GTX used different rods than the Miata but Mazda lists the same part number for replacement.
