18g and 20g, spool up rpm?
As per title, the differences between the two seem to be compressor inducer size and 1cm sq difference on the turbine area.
My question is say with peak boost of 1.4 bar at what rpms can I expect full boost on a std wrx ej20? Ie what is the difference between the two?

Of course, but if the only variable was the turbo, what rpm difference we speaking? My old 20g was full boost 1.4 bar at 3600, what we speaking for the 18g? 3300?

Smashing, that's bang on 1.4 bar at 3600, obviously goes on to make more boost past that. Just wonder how this compares to an 18g? Are we only speaking a couple hundred rpm?

It sure was, i had standard exhaust manifold too. just a decat and a larger up pipe. Will see if i can dig up the graphs for you. It was a proper little animal. Just ran out of puff at the higer revs which was why i went for a MD321

Seems like most guys running 1.4 Bar. Any idea what timing? Curious if a little more boost and less timing would make more or less?
Maybe i need less boost and more timing on mine. !.5 Bar and 21 degrees on 98 Octane!

Not sure how when will hit full boost,but I would expect around 3500RPM,this really depends on how much boost,headers etc.

From my experience with more boost you always retard the timing, more boost with less timing will make more power, the flow of the engine and turbo being the restriction.
