I am thinking about doing the same this summer, but also update my extension tank and it's cap and my water pump from turner motorsports with their upgraded series of all these items, I will also probably order their pro pulley kit as well while at it.
The upgraded water pump has steel parts inside instead of plastic not to mention it is more efficient, with pulley kit I am expecting less wear on water pump and at the same time more hp as well.
I hear that oem water pump in time eventually fails, and when it does engine overheats almost instantly. I personally don't care if item is oem or aftermarket I just pick the part that I feel and think is superior. For example, I will not use oem bushings on my car but I will also not use aftermarket control arms either, or I will not use oem fluids but at the same time I would never use after market sensors. IMHO
