Teching Inline 4-Cylinder Metal Engine Model Kit builds into a working DOHC inline-four with an exposed twin-cam, chain-driven timing layout that shows how motion travels from crankshaft to valvetrain.
Why it is listed here
Compared with tab-and-sheet metal kits, this is a motorized build, so the pistons, timing chain and camshafts move together once it is finished. At about 4.72 lb and just over 7 in tall, it is a heavy, solid shelf piece next to etched steel models. The listing says basic tools are included and the kit comes in a durable metal case, which keeps its 250+ numbered parts organized through a roughly four-hour build.
What the build involves
Numbered parts come in protective foam, so lay out only the parts for the current step and follow the full-color manual in order. Turn the crankshaft by hand to check that the timing chain and camshafts move smoothly before you run it on the motor. The listing gives 14+ as the minimum age, and at over 6 in wide it needs a sturdy desk or shelf rather than a narrow ledge.
