Had a coolant leak tonight, noticed smoke when pulling into my friends driveway, so i popped the hood and it had ignited, good thing i had an extinguisher... this ever happen to anyone?

 

It happened to a lot of people, actually - forced a recall & was a large reason why the RX7 fell on its face in the US. I assume you have an early 93? You might want to check to see if the recalls have been taken care of.
