We completely love tiny, absolutely practical engines. And we all know Motor1 readers love them, too. YouTuber JohnnyQ90 undoubtedly loves them; a lot of our tiny engine training has come from this channel. And now now we have one thing new—an honest-to-goodness turbocharged four-cylinder.

The engine is an Enjomor GS-L4, a 32cc DOHC four-pot that, in keeping with the StirlingKit web site, can spin to 12,000 RPM. This one is additional enhanced with an Enjomor turbocharger equipment, which incorporates the turbo, a cost pipe, an exhaust pipe, and an air filter. The video is technically a evaluation of the turbo, however we recommend however sticking round for the tip to see (and listen to) the teeny four-cylinder in motion.

If just a few issues appear off about this turbocharger, you are not mistaken. There is no such thing as a wastegate, the oil inlet feed is not in the most effective location, the turbo is not in a great place, and the cost pipe could possibly be straighter. Because the turbo comes aside, we see extra points as effectively. The tolerances do not look notably tight, which is crucial if you wish to make any increase.

The elements are 3D-printed in metal and aluminum, so the castings aren’t very clean. And when every thing is finally put in, it seems to make little or no increase, if any. We do not even get any turbo whistle. However the exhaust observe positive sounds good. It’d even be higher than the small flat-four we discovered again in 2023.

Maybe we’re being too crucial. It is a practical engine, nevertheless it’s nonetheless only a scale mannequin. Its solely function is to look good and sound cool, and it succeeds at each. We love the little turbo on the facet, spinning its coronary heart out whereas the engine screams. It could be neat to listen to a correct whoosh beneath throttle with a bypass valve venting upon launch, however hey, it is a begin. 

The engine is at the moment priced at $999, and the turbo equipment is a $229 improve. Is that this setup definitely worth the worth? Bounce into the feedback and tell us.
