Forget about Full/Half Bridge. you don't even know what they are, and 99% of the people don't need it.

Street port, usually just enlarge the existing port at a "reasonable" amount. it's trying to improve the engine's VE to improve performance.

cost? if you have to ask, you can't afford it

Read this. It will explain what each type of port job is, as well as their prices to do it. http://www.rotaryheads.com/porting/rx7-porting.html

Buy "Street Rotary" book on amazon too. I love it. Well worth the money.
