im thinking of getting my engine rebuilt and since its gonna be torn down anyway, i figure ill have it ported as well.

what are the different port jobs and what are they?

also what kind of horse power gains should i see?

 

Here's a link to RETed's sight: http://fc3spro.com/TECH/PORT/porting.html

You can see several pics of the common ports done on rotaries. A street-port is by far the most common type. The street-port picture from the link is of a turbo 4-port.

Except you have an N/A which is a 6-port. You can street-port a 6-port as well, except it'll look a lot different. Here's a great tip to finding 6-port, street-port pictures: SEARCH.

Try searching for, "N/A street-port" or "streetport" or "streetporting an N/A" or "porting"... Lol, you'll find what you need.
