Man’s fascination with Lego stems from the insatiable need to build things. Whether it’s a small Lego kit or a 3,599-piece Bugatti Chiron, the act and subsequent gratification that comes from building Lego kits is a big reason the toy line remains as successful as it is today. Some people, like Instagram user Replica Motorsport, even make businesses out of the kits they build. Replica Motorsport’s Lego gig involves recreating some of the auto world’s most beloved engines in miniaturized sizes and then selling them to those interested enough in trying to recreate the build. It’s not something casual Lego builders would be interested in, but for the auto-obsessed lot out there, and there are many, these small engine kits are the perfect embodiment of your Lego fandom.
