Porting
 

Im interested in porting my rx7 but i dont even know what it does. Can anybody elaborate?

Porting increase the amount of air being taken in and exhaust taken. If you're running turbo, helps spool the turbo a bit more faster then stock ports.

porting (in a rotary or reciprocating), when done right, basically increases output by improving the airflow throughout the engine. there are serious variables to consider, such as: velocity, idle quality and powerband, so it's not just a matter of going in ham-fisted and making all the ports BIGGER!

here is my first shameless plug of my porting thread. you can check it out and see if you find it helpful. some photos are still missing, but the information is pretty much complete.

My simple way of describing it to newcomers is its similar to installing came and doing head work on a piston engine changing intake and exauhst durarions hence causing ur loping from piston engine
