Intake manifold project

I agree The OEM intake is "sufficiently" efficient for the standard engine. If you replace the oil pump gears with billet and remove the rev limit of the OEM ECU

I agree

The OEM intake is "sufficiently" efficient for the standard engine.

If you replace the oil pump gears with billet and remove the rev limit of the OEM ECU then you might expose the airflow limits of the stock porting and manifold.

Similarly, if you increase the compression (whilst remaining NA) you may also expose the airflow limits.

The OEM heads/ports and manifold will only flow enough air to make torque for 430-440 hp at ~7500rpm+. Running NA at 13.5:1 (on E85 or FIA 106RON race fuel) you WILL certainly need an upgraded inlet manifold and possibly ITB at that.

If you are FI, who cares - the above atmosphere pressure will resolve 97% of the flow restrictions.

IMHO, the only folks who need an inlet manifold (unless you want engine-bay bling or bragging rights) are those hard-core racers who are forced to remain NA by their engine-mod rules.
