I'm having trouble (still) with my turbo GSR overheating - the water pump is relatively new (was replaced 5000 miles ago) and it seems to be still in good condition but I'm wondering if there's any chance that the mechanic may have put a lower-flow water pump on or if there is a higher flow pump that I could put on that is a stock honda part. I don't know if this is even possible but I thought I'd ask.

TIA
