Perseverance---

: continued effort to do or achieve something despite difficulties, failure, or opposition :

This is the word anyone in the sport of n/a tuning would learn to live and love. Having no boost pressure, auxiliary injection, or even supercharger pulleys to play with, naturally aspirated is both difficult and also very rewarding.

With that said, here is our most recent shop car results! Using all learned knowledge over the years from my original ITB 20b, the good ol' 230wheel 1st gen "test mule" and many other projects, finally have the semi p-ports in action! Its a beta version, and really just the beginning. No rumors, no theorizing today. Just the findings and results.

The engine setup-
20b n/a, 9.7:1 rotors, CLR balancing, race rotor bearings, stock stationary bearings. circuit porting, and exhaust porting, semi p-port. Dry sump mazdaspeed front cover. Oil and coolant modifications.

Exhaust-
Custom stepped inconel header, fully adjustable design. 3.5" main exhaust going to twin 2.75" pipe and dual center exit
