Hey Ben,
your list of upgrades should do the trick.
My old car had a GTR fuel pump, ECU and a adj fuel reg is also a good idea for your car.
13psi is sensible as standard injectors in my old car ran lean at 1 bar over 6000rpm.
I'm sure your next step will be bigger cams, injectors, adj cam timing gears and 1.2 bar of boost should make your car an absolute weapon....
its a nice change to see someone slowly build up their car sensibly with well thought out mods...... good luck dude..
