G'day everyone. I'm new to the forum and have a question regarding reliability and less important driveability of a highly mod'ed car. In particular a 996TT, because that's what I have. It is completely stock, apart from a GT2 wing and tiptronic. I want to modify the car and get more from it, but I am worried about reliability. It is my daily driver and track car about 6 times a year. initially I was going to start with sports headers, billet divertor valves and an ECU flash. I believe just these will lift HP to approx 500. The question is, Will it still be reliable? I know Porsches are lengendary for over-engineering, but how much is too much?? Comments and feedback much appreciated. Loving the cars, mod's, pictures etc.
