Our Engines & Gearboxes range covers LEGO-compatible engine kits across every major layout — V8, V10, V12, W16, flat-6/boxer, inline-4, rotary — plus aircraft and motorcycle engines for builders who want the mechanism rather than the whole car. Every model in this range is designed to show real internal structure: pistons, crankshafts, valve trains and timing chains built to actually move, not just imply motion behind a static shell.

Most kits in the range are motorised — a rechargeable battery pack and electric motor drive the crankshaft, so the pistons genuinely fire in sequence rather than sitting still for display. Several also pair with a separate gearbox or transmission kit for a complete powertrain build. If you're after a LEGO-compatible V8 engine kit specifically, or want to compare V8 against V12, W16 or flat-6 layouts before choosing, every option is here with piece count and scale listed up front.

These kits work well as standalone display and desk pieces in their own right, or as a natural next step once you've built a few complete car kits and want to focus purely on the mechanism.
