FAQ
Q: Does the engine move?: Yes — rotate the crankshaft and all six pistons move in sequence, showing the V6 motion.
Q: Does the turbo spin?: The turbocharger is static for display but designed with realistic housings and charge-pipe routing.
Q: What’s the difference between OEM and turbo versions?: The OEM version includes the factory-style intake and exhaust manifolds, while the turbo version replaces these with a high-mount turbo layout and custom piping for a modified look.
Q: Is this the same as the L67?: No — the L67 uses a factory supercharger. This kit represents the naturally aspirated Ecotec and a custom single-turbo conversion version.
Q: How does it display?: Each engine can freestand securely on its sump or be mounted on an optional Mechanical Miniatures stand or crane (sold separately).
