E36 Engine swap or Bolt on Turbo

Hi guys,
I just would like to get some opinions on engine mods.

I have an E36 with the M52 motor, full stage 1, CAI, chipped and swapped out the diff for a 3:15 variant.

What is the opinion of the fanatics? Bolt on Turbo or engine swap.
I would like the car for everyday use if need be.

Thoughts?

Thanks
