Thanks for the info, Val.  I think I'll order the 92C unit then from germanautoparts.com.
Not sure what is in mine, but just getting ready to drain/flush the cooling system and put some new 
hoses on it, so may as well swap out the t-stat.  Yes, I have a decent cooling system, an upgraded 
3-row radiator and I fashioned an overdrive pulley for the water pump, to increase the flow.  The 
1.9 engine was swapped in by the previous owner, replacing a 1.5 or 1.6.  Also have regeared the 
transaxle to a 3.67 final drive, so trying to eek out as many MPG out of the setup as possible.
