The S7 Europa was really an onroad engine for its time. If you plan on putting it in a truggy I feel you may be disappointed as it will lack the bottom end necessary for ultimate fun factor/racing scenarios.
If you want a .21 engine then the Fire11 is more than enough, the B11 will have great results and drivability, the MT series are .28 and will be more than powerful enough and if you can find one out there used a WS series engine (WS7 II or greater such as WS7III or WS9) were great engines but fuel hungry.
