Title: DBW Intake Manifold (small port) on Big port AGU Head Post by: ibizaCUPRA18t on January 09, 2018, 08:21:32 AM My 1.8t engine that I'm working on for my MK1 Caddy project has been AGU Head swapped, and is DBW. I don't have information about the engine block, but I know its a 06A newer model. So only the head has been swapped I am guessing. However, yesterday I unscrewed the Intake Manifold to clean it and while mounting it back on I noticed that the manifold ports are smaller than the head ports.
Does this mean I have no advantage whatsoever, since the air going in is only losing pressure (due to larger ports/smaller intake) and not gaining mass. However, am I at a disadvantage? Also, do I need to find a large port intake manifold and swap the throttle body to make it work properly? If I am at a disadvantage like this, then please notify. If neither then I will leave it like that.

You dont need a big port head below 500/600/700hp.... |
