It's already known the Chevrolet 153 engine is among the most versatile powerplants ever made, and it could eventually retain some foothold in the new-car market at least in some regions with less strict emission rules given some technical updates such as multi-port fuel injection. But it had already been neglected long ago, with some models made by different GM divisions relying on other engine ranges even though the 153 could eventually fare somewhat better on them. At least 5 examples can be highlighted.

Many aspects may lead to differences in the engine selection for some cars and trucks according to the market, such as emissions compliance, local content requirements and repurposing of an ancient engine in order to avoid investments on newer tooling to manufacture more advanced powerplants. Among those examples, at least 5 can be highlighted.

Even though some gasoline-powered (and occasionally flexfuel) small-block V8 remains as the most usual option for those looking for an engine swap in the United States, a serious contender appeared when Cummins released its R2.8 crate engine with an aim set specifically at the repowering market. Even though its horsepower rating may not seem so outstanding at a first glance, not to mention other aspects such as the perception of a higher amount of cylinders as a premium feature, it became in fact quite competitive and can serve reasonably nearly every vehicle to which a small-block V8 would be more frequently applied. Among so many vehicles which could be a good receiver for the Cummins R2.8 crate engine, some which could be highlighted are...

Even though some Subaru models such as the early Outback have a die-hard fanbase who is obsessed with the Boxer engines, it's far from being as perfect as it seemed to be. I must confess I have actually prefered the old-school Volkswagen air-cooled Boxer for a long time, which by the way can have its displacement increased with some performance kits allowing it to get figures similar to the EJ-series Subaru engines. Another kinda controversial option that I would consider to replace a stock EJ-series into a Subaru would be some V-Twin engine such as the ones traditionally fitted into custom/cruiser motorcycles. Among the reasons that would lead me to consider such option, at least 5 can be listed.
1 - fewer parts: since it would have half the amount of cylinders, depending on engine model it will lead to have around half the amount of moving parts, occasionally less than half considering most are either OHV or SOHC while the EJ-series engine had resorted to a DOHC valvetrain for most of its versions.
2 - availability of different displacements allowing enough power and torque: even though it may seem more likely to become underpowered with most of the stock motorcycle engines, there are some within the 1800cc displacement range which would already have enough power, not to mention all the aftermarket parts and even some entire engines usually based on older Harley-Davidson designs even surpassing the 2000cc range.
3 - setting the engine back: this would allow some improvement to the weight bias, since the Boxer only allows a longitudinal fitment ahead of the transmission.
4 - servicing eventually becoming easier: even though it may not be the case for every V-Twin out there, the access for some components such as spark plugs in the EJ-series is kinda hard.
5 - just for the experience: sometimes it's tempting to try some different engine configurations just for the sake of it...
