Re: Technical question reguarding the radiator fan.
Jason: The typical reason to wrap the header/s is to maintain that thermal energy (keep the gas hot) prior to feeding it into a turbo. The hotter the exhaust gas reaching the turbo, the more energy there is to spin the turbine. In your case, the gas has left the cylinder already. There's no way to use the extra energy in the exhaust pipe. However, the wrap does keep you leg cooler.
SpDd: My 01 has been no more or less troublesome than any year, as far as I can see using other forum members as my comparison. My tranny has been fine so far, but I do not speed shift and always use the clutch. I've replaced my one-way, and bent and replaced my steering shaft due to a roll... that's about it for major service in the 2 years I have owned it. Also, subject change - ideally, to maximize the Carnot cycle, if all the energy during combustion were converted into mechanical energy, the exhaust gas would be at ambient (impossible, I know), so the cooler the exhaust gas, the better - more power has been transmitted to the piston... of course Otto engines are no better than 50% efficient for a reason so you can't get there.
