Unported those Mivec heads flow better than our Stage III heads iirc. I know ported with bigger valves the Mivec flows better for sure. Both of those owners have bigger manifolds, exhausts, intakes, intercooler pipes, etc to make a more efficient setup. If they can't run more than 20-23 psi, then there's something else holding us back or it just isn't possible due to the inefficient design of an older V6 compared to a new 4-cylinder.

thats what i was saying earlier when i posted the vid (leonels car). him and italo have the same setup except italo has slightly different turbos and mivec. bottom ends and manifolds are the same iirc. thats kinda why i lean on cams being the culprit because many people have changed every other variable but as anyonebutme always says, there are no truly *good* cams made for our cars yet. you are almost certain to not gain max potential power with just a cam swap unless you put adjustable cam gears on there too. i wish someone on here had the pull to investigate into getting cams made and swapping them in for direct comparison
