Hi Audi fans, After a long and unsuccessful search for a 87 or 88 5ktq with less than 90k miles on the odometer, I am thinking about settling on an 87 5kq. I realise there aren't many options available for increasing power on the non-turbo 10valves, but any reasonable suggestions would be useful. Mileage is very important to me since I commute 42 miles round trip everyday. Matt Jackson Seattle, WA
