does anyone know anybody that knows anything about rotarys.?

My buddys got a t2, and I worked on it for him one weekend, i did a manual boost controller and an HKS fuel cut defender to boost it to 13 pounds. It hauls ass, feels like its close to 300 horsepower or somewhere in that neighbourhood. I scared the shit out of myself working on that thing...the boost actuator..or whatever its called (on the passengers side fender)..the vacuum line burst off....then the car wouldnt start..haha i thought teh car was right messed up or something . thats about as far as im willing to go into rotaries, totally clueless.

for such a simple engine,they're quite complicated,lol
