I have not moved my coolant reservoir yet. Just haven't gotten to it yet (need to buy a new hose for it). NOLAjeeper installed his reservoir in the stock location and he seems to like it.

I'm still running the stock spark plugs. I'm not aware of any specific reason to change the plugs. The turbo has been tested/tuned with stock plugs, and I'm no expert on spark plugs, so I feel best leaving it the way Prodigy intends.
