Is it possible to put a 1.2 8v with a turbo in my cinq? And if it is what will I need to make it happen

Yes, I suggest you read my, or Lecook 's or Honeymonster 's threads first

yes its very possible... its also not cheap.. but my god its addictive

Money , money and more money , lots of time and effot

I think my turbo adventure costed me a complete GP tjet in good shape in money, several years in time, I did however learn endless amount of car and engine control stuff...
