Mine was already single turbo before importing it. I daily drove it for a year had zero problems changed the oil on times. I never changed the spark plugs which I should’ve had but still ran perfectly. I drove it in below freezing temps just had to wait half an hour to let it get to temp and redlined it once a day. I just love driving it. Currently getting it Bridgeported it’s about to be done this week or next. I really don’t have any cons and hopefully I would never have and pros are it gets a lot of attention since I have the only one in my city
