All good points. I don't think your car is simple. You have replaced just about everything except the long block. Do I really need to detail what you've done on your car? Fuel pump, injectors, MAF, airbox, turbos, intercooler, BPVs, turbos again, charge pipes, clutch, downpipes, etc. etc. 15 other things I'm missing. I would consider simple to be or chip/intake, or something that can be done in a day's work. Not something that takes a shop a week.
Back on topic though... Looks like a nice little car, but it will be way too expensive for me. Seems to me like the v8s have been far far far more reliable than the 2.7t ever was. Just gotta do the timing chain tensioners at 100k.
