ok i have a 1982 280zx. one of my buddies had told me about a twin turbo 300zx motor that he has and if i wanted it. my question is how hard will it be to put one of these motors in my 280zx and what would i need to change on the car besides the engine?

your advise is greatly appreciated!

more effort than it's worth.

you'd need the engine harness, ecu, engine with all accessories, transmission, custom driveshaft, custom engine mounts etc etc etc.

depends how much you want to spend for it, cause it won't be cheap or easy.

Oh go ahead and do it!! ;) Or you could drop a Chevy 350 in it. The guys at Hybrid Z know all about this.
