where on the enternet can i buy a 180 t-stat and a fan switch that turns on the fan at a lower temp

 

Summit has them in there cooling section.

 

JET-60600 will this switch work on my firebird. also when i get the 180 t-stat and a switch can i use a hypertech street runner aftermarket chip? if not which after market chip should i go with thes cooling mods super chips, fastchips, hypertech, or jet?

 

will this chip work fine with my applications? Stage 2 #19117S

 

Do you need to change the ecm chip when going with a 180 stat and a faster opening fan switch?

 

First off, 3.1s don't have an external fan switch. The fan is controlled by the ECU. Second, all of the cookie cutter aftermarket chips are an utter waste of money. They add a tad bit of fuel and a tad bit of spark advance at WOT. Sadly, an AFPR and mild timing adjustment at the distributor will generally reap better results. Nothing wrong with the 180 degree thermostat, though.
