I can get you a complete 1.6 that may or may not need to be rebuilt for slightly more then you will pay for the parts to turbo a NA. It all depends on the condition of the engine I find.
If you do decide to turbo your NA, get a boost and EGT gauge.
I have intake piping (air box etc) and possibly a pump and possibly the manifolds.
Don't forget you'll need the turbo oil lines, the pan, and the oil filter mount.
