Default KR, 3800 series 1

My fiero runs alittle hot, It normally runs around 220. When it is around 220 if I go to WOT I start to hear a loud clicking from the engine??? would this problem be caused by KR? I put a Gtech and tried it out when the "clicking starts HP drops tremendous. Any Ideas
I have a 93 3800sc with a 94 sc and 70mm TB with the 2.5" 93 pulley. 2 heat range colder NGK plugs. ANy help? I am guessing most will say lowe rtemp thermostat. Anything else????
DO you think it is KR is even the prob? When engine is cold it is not an issue.

It sounds a little to me like KR since the horsepower drops tremendously. Yes I'd get the 180 stat to keep it cooler. But that won't solve everything.

yeah, but he has the engine in a mid-engined configuration, thus there isn't a radiator with air ramming straight onto it, it has to be ducted in, thus there is less of it, thus your engine in his Fiero (hence his name) runs hotter, thus... well, you get the idea

you can get the thermostat at just about any auto parts store, you don't need to order it. and with watter injection, you gotta be real careful otherwise you may hydrolock the engine, and that'* just not good...
