Big port head flow tuning
Hello.
I'm having a '84 JDM Celica AA63 (coupe) with big port MAP-sensored 4AGE. It has miled 160k kms and now it's time to have a good rebuild and free some horses. I want to find some hidden horses in my head, so please, help me  Port enlargement is defo not what the big port head needs. Did anybody have ported or flow tuned the big port head? What have you done there, except removing some marks of factory castings and meeting parts to each other? I know that polishing itself doesn't get any result except the fuel flows on the walls and the result is lean mixture and crappy power. |
