how to port my 1993 rx7
 

As the title says. Is there a step by step guide

Here's a video which shows the porting process:


Note that you should not copy those ports, but instead you'll want to hit up your favourite rotary vendor for a set of porting templates which suit your purposes. In most cases, that means a street port. My favourite TII/FD port job is RB street turbo exhaust, Mazdatrix 6 port primary ports, and RB big turbo street secondary.

FWIW....
