Default Defined 20b n/a semi p-port. 421rwhp
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.

Intake setup-
Stock 20b intake with custom sheet metal plenum and 90mm TB. 3 x 35mm individual throttle bodies for p-ports. 9 fuel injectors. Triple staging.

Accessories-
Racing beat front pulley, mazda comp waterpump pulley.

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

Standalone-
Electromotive Tec3R ecu, and inductive coils.

Fuel-
ATL 13 gallon fuel cell, Walbro fuel pump, 550cc x6, and 200cc x 3
