3 questions:

what was the lightest year of FC?

would it work to swap a series 5 turbo motor into that car?

would it be possible to swap an FD engine in?

 

This has been done to death. It's all the upgraded bits in a Turbo that make it heavier than a NA. Throwing a turbo engine into an NA is asking for trouble, an FD engine even more. If you want a turbo, buy a TII.

 

welllll....yeah, but if you swap a TII motor into a Sunroof-less n/a then it'll be lighter than your box-stock TII


The lightest year is 86 base w/ no sunroof or any power options.
