Yeh, what he said.
I have the .50 and 90 sports.

I like the standard Sport Jett .50 myself.
the Fire is (Front Intake, Rear Exhaust) and really set up for a tuned pipe.
The BSE is a Bar Stock Engine, very nice looking, but minimal performance gain over the sport jett (don't hammer me too bad for that Bob, and correct me if I'm wrong).
