Probablly should know but....
 

Is a 84 300zx front wheel or rear wheel drive?

and how many lugs are ther four or 5?

Re: Probablly should know but....
 

All of them are rear wheel drive.
the only 300zx's with 4 lugs are 84 and 85 non-turbos.
all the non-turbos have 15" wheels,
84/5 turbo's have 15" wheels,
and all other turbo's have 16" wheels.
the only exception is the anniversary edition which is an 84 turbo with 16" wheels.
