Hello first of all, I’m new here and have already informed myself a little about the topics around the calibra. Of course I don’t know if I have the right to open a new forum. My concerns or/or questions: I want to buy a Calibra as described above very soon. My questions to you are: How much horsepower can I bring it? How much harm can I do to the engine? What can I do at all? What do you recommend to me with the engine, turbo, exhaust etc. turn/improve, or buy? And at the end a somewhat stupid question, the tachometer at the dashboard, does it go up to 260 or up to 280? In the Internet/youtube there are always other tachos shown. So if you can help me that would be very great. Thanks already in advance.
