1 - Perkins 404: available either in naturally-aspirated or turbocharged versions, this Diesel engine could be regarded as a natural evolution considering the usage of the Perkins 4-108 engine in some Spanish versions of the CJ-3B. All the 4-cylinder versions of the 400-series Perkins engines come in the a 2.2L displacement, just like the gasser it would be replacing, and it's also worth to notice the gear-driven OHV valvetrain and injector timing are not so failure-prone, so the maintenance would not be too significantly more complex;
2 - Yanmar 4TNV88: a comparable engine to the Perkins 404, it has been widely fitted not only to stationary/industrial applications and agricultural machinery to be also found on sailboats, to which once again the Perkins 4-108 had been widely used as auxiliary power. Available either with natural aspiration or turbocharging too, this engine has also been used for swaps into compact trucks even in the United States, even though some performance upgrades are frequently added in order to meet the requirements for these rigs which even in stock form are larger and heavier than a CJ-3B;
3 - Chevrolet 153: even though it's also an old gasser just like the Hurricane, the gear-driven OHV valvetrain is an improvement over the precarious intake-over-exhaust approach. This has actually been one of my favorite engines for a long time;
4 - Volkswagen air-cooled flat-4: even though it may seem quite weird, a "Veep" still attracts me. Even though the most usual approach for such swap was to replace the entire frame for a shortened Volkswagen one with a makeshift rear engine compartment, trying to fit the engine upfront would not be discarded immediately;
5 - Hatz 2L41C/2M41: even though a 2-cylinder Diesel engine may not seem so attractive at a first glance, its 1.8L displacement range is once again comparable to the Perkins 4-108, while the air cooling is also quite tempting. A major downside is the weight of those engines, even though the small amount of cylinders may fool someone to believe it would be a hassle-free engine swap...

A somewhat unrefined engine, featuring a gear-driven OHV valvetrain and with its peak power and torque RPMs being somewhat low for modern automobile standards, the 3.7L Toyota 1FS engine is more easily found on forklift trucks and other special equipments. However, many factors could turn into a reasonable motivation to fit such a crude and seemingly unsuitable engine to a modern vehicle. At least 5 examples could be highlighted as tempting to swap the 1FS into:

1 - Renault K-Type engine: since it shares the bellhousing pattern with the old Cléon-Fonte and the "Energy" engines, and the Cléon-Fonte had some derivatives fitted to Volkswagen models in Brazil from the late-'80s to mid-'90s, a K-Type engine swap doesn't seem so much of a rocket science task;
2 - Volkswagen EA211: just like its predecessor EA111, the EA211 is a more compact alternative to the EA827 and its subsequent replacements. With the 3-cylinder 1.0L versions available either with natural aspiration and port-injection or turbocharging and direct injection, while the 4-cilinder takes the 1.2L to 1.6L range with the same availability of either natural aspiration and port-injection or turbocharging and direct injection, there are plenty of options from a more frugal to some spirited power and torque figures;
3 - GM Family 1/Family 0/Small Gasoline Engine: tracing from the use of Chevrolet 153 engines for swaps into Volkswagens in South Africa to the present-day downsizing trend which renders some turbocharged variant of the smaller engines available on newer Chevrolet cars and crossover SUVs suitable to perform basically the same duties the old 153 would perform, it wouldn't really surprise me to see some random Chevrolet engine ranging from 1.0L to 1.8L also either naturally-aspirated or turbocharged being considered as a suitable option to swap into a Beetle;
4 - Toyota TR engines: tracing from the usage of the Y engines for repowerings into Kombis in South Africa and some Asian markets, with the TR being its replacement for some applications, it's no surprise the 2.0L 1TR-FE would be an interesting option for performance and long-term reliability while the 2.7L 2TR-FE could seem quite overkill yet tempting for a sleeper;
5 - Fiat FIRE engine: ranging from 0.8L to 1.4L and with turbocharged versions available within the largest displacement, it's also widely used with alternate fuels such as ethanol, Natural Gas and LPG. Requires an adaptor plate to be coupled to the original VW transaxle, but it's no rocket-science.

Once a popular powerplant for European vehicles, also widely used for other applications such as marine and stationary/industrial, the Perkins 4-108 was a development of the 4-99 engine originally released in '58. Discontinued only in '92, it could eventually be perceived as somewhat archaic by then due to the 3-main-bearing crankshaft and overhead valve layout with a gear-driven camshaft in the block, even though it could still fare reasonably compared to modern overhead-camshaft rivals with a 5-bearing crankshaft which started to appear in the '70s. At least 5 vehicles which were highly successful in the '90s and fitted with some OHC engine for their Diesel versions would actually be not bad with the seemingly-outdated Perkins.
