Can you put a dohc engine in 3000gt base model?

It is possible to put a DOHC engine into a 3000GT base model, but it would require a significant amount of modification and fabrication. The base model of the 3000GT came with a SOHC engine, and the DOHC engine from a higher trim level or different vehicle would have to be adapted to fit. This would likely involve altering engine mounts, wiring, and other components to accommodate the new engine. Additionally, you would need to consider upgrades such as a stronger transmission, rear axle, brakes, and suspension to handle the increased performance of the DOHC engine. It's essential to carefully plan and execute such a modification to ensure its reliability and safety. It is recommended to consult with automotive professionals or enthusiasts with experience in this type of customization for guidance.
