Best I've done on my VF34p18 at 1.7bars was 280hp/400nm on verso tune
with STI top mount, decapps, cai, exhaust etc etc
But with p20 and cams I'm sure you should be able to squeeze that extra 20hp tho...
Going twinscroll is no different either(not worth the upgrade imo)
I'm still at 280hp/401nm lol but with slightly less lag and the twinscroll sound as well
Get a TD05-18g or maybe even a 20g and with the cams it would help out a lot and will get you 300+hp
