    75mm I believe. Don't waste your money on a bigger one, just port yours. I learned this the hard way. The opening on the intake is the same as the throttle body so going bigger with the throttle body does nothing.

    But Your Still Limited To The Size Of The Butterfly, With Porting It Will Flow Better, But You'll Have To Port The Intake Either Way. In The End I'm Going To Have To Do Both As Well As A Mass Airflow Sensor, And Larger Injectors. This Is All Perliminary Planning At This Point...

    Unfortunately, you really can't port the intake, so the only option is to upgrade.
