Conversion of the Cayenne S to Turbo Optics

Hello, I spent a few hours last night i, forum, but I was not really smarter at 3.30 am anyway. I would like to buy a Cayenne S (V8). I don’t like the front at all and I would like to have it converted to the turbo front. The friendly told me this morning that this is not possible, because the coolers etc would have to be rebuilt. Otherwise the coolers would not get enough air… Did someone carry out the conversion At the rear it doesn’t look any different. Would have liked the 4 end pots and the turbo bumper including the new rear lights. The friendly has called Techart as the only possibility, but I would prefer series (mostly Facelift). Techart is too expensive for me and Magnum looks quite exaggerated. Gemballa also offers the conversion, but they are also quite expensive and too heavy. At mobile.de is such a conversion, but unfortunately the already 96,000 km on the clock and the V6 machine. A In addition, the dealer makes a rather unsavory impression…! Thank you for your answers…! Greetings Andi
