head/ injector queries

[t18con]

1. what sort of gains would you expect using a large port head on a k04 running approximately 25 psi. until i get the intercooler turned into a single pass, id still be using the original inlet manifold though.

2. im running a tt 225 injector setup with 4 bar fpr. what sort of bhp would this system stop atomising the spray correctly?

what would you do for an intake manifold? on largeport

in the mean time, itll have to be original ibiza/tt manifold. have agu in preparation for intercooler change.
