The SR20DE is not the bottom of the heap in the SR20 family. While looking at Russian automotive sites, I found a ground-pounder called the SR20Di. It was rated at 115hp, and was an option in the P10 Primera and Primera wagon in some european countries (Italy, Russia, Poland, etc.).
Throttle body fuel injection (noted by the "i" (http://www.freshalloy.com/site/features/tech/engines/home_codes.shtml)), or "central electronic fuel injection" was used in place of the more advanced mult-port fuel injection (one injector per cylinder) on the SR20DE. Like it sounds, the Di's injectors dumped fuel into a single throttle body. I guess you could think of it as being a degree of complexity above a carburetor, like something you'd find on a lot of eighties compacts.
It seems like a waste of a SR20 when there were smaller, ligher Nissan engines that could make the same power. The author of the article I read theorizes that the output was ECU-limited by Nissan for mileage and emissions purposes. This makes sense, as europeans tend to pay more for gas, and eastern europeans in particular don't always have access to ah, Amoco premium superclear.
So that's the SR20Di. File it under esoteric Nissan knowledge. The engine was never sold in the home market Primera, so we'll never have to worry about "accidentally" getting shipped one by an importer.
If you want to read the rest of the history of the SR family, plug this into Babelfish (http://world.altavista.com):
