Old/new vehicle question?
Yes but it takes a s***load more time and cash than they made it out to be. For starters, the engine that they used is quite complicated to transplant, even in normal Skylines and other Nissans. It's a 2.6L twin-turbo inline-6 engine most commonly seen in the R32-R34 Nissan Skyline GT-Rs. They can withstand quite a bit of horsepower with stock internals, but fitting it into a different car is an entirely different story. Simply because you can't just drop the engine in there. You have to replace everything engine related so that it can withstand the strain of the engine, and a new gearbox to suit it as well.
