I just ordered the NST crank and water pump pulley's from their website. I went with the standard size (OEM). I wanted to get either the 20% underdrive crank pulley, but didn't want to risk cooling problems, or get the set up i just ordered and run the 20% overdrive alternator pulley, but don't want to have charging problems. I wish they had a stock size alternator pulley. Are the 2 concerns I mentioned (cooling problems, charging problems) valid, or am I being stupid?
Any opinions? Thanks
