On the Mazda247 boards (you'll have to search), someone was doing something similar. Installing a fuel-injected D15B into a Protege.
The big issue is... the mounts issues, electronics issues and assorted headaches with fitting an engine that turns the wrong way round into a regular engine bay means you'll be spending a lot of money for waaaay too little benefit.
Better to get a JDM or European Mazda engine with low-displacement and high power to swap into that Mazda or eco-mod the stock motor.
There are some tricks that can be done with Mazda mills. If you've got a Miata, there are the Euro-spec cams (drops it down to 90 hp), which should do well combined with an aftermarket air-fuel controller.
Mid-90's Mazdas have a wide choice of 1.5 and 1.3 liter engines that will fit, as well as the European diesel.
The last-generation BJ Protege had a huge variety of engines, from 1.3 gasoline (sweet, economical little thing) to the 2.0 turbodiesel (which is where they got the intercooler for the Mazdaspeed Protege from... and which has fascinating gear ratios...)... all as far away as a phone call to a motor importer. Performance swappers usually go for Probe/MX-6 2.5 liter V6s, but across the pond, it's not uncommon to see the smaller 2.0 V6, as well. The Supercharged Miller, on the other hand, is a truly RARE conversion.
If you want to work with the stock motor, for the 2.0 FS-DE Protege or Protege5, the 1.8 liter FP-DE cams
may just fit in the motor... and they have a lower profile... it should be easy to find a 1.8 owner willing to swap up for more power... better yet, use the FP-DE motor from the get-go, as that's sweeter revving. There are guides on cam-profiles between regions at
Protegé FAQ
Then there's the 626 transmission trick for the same car... which gives you a longer 5th gear. Some owners with autos have switched wholesale to 626 manuals, which give both a longer fifth and a longer last gear. Also, for some reason, the gear synchros aren't as crunchy on that transmission, but that may just be me...
And since the Protege FS-DE is tuned so conservatively and has such good knock resistance, you can lean it out pretty far with an AFC in an attempt to find better economy.
There's a lot you can do within the stuff available for the car without looking at exotic cross-manufacturer swaps which will involve more wiring and custom fabrication than its worth for a measly small jump in MPG. You can even fit a rotary into an MX3... but I'm not sure you'd want to do that if economy is the goal...
