Can't afford a Honda

I'm fron the UK and have been learning from Hondatech for about 4 months, my friend has got a civic with an Integra type R engine.
This is my engine, I'm I've stipped it and I'm looking for around 300-400whp, the things I've considered are:

Equal length manifold
Carbon intake/plenum with larger throttle body
T60-1 turbo + external wg
24"x11"x3" intercooler
DTA engine management (standalone) distibutorless
Some higher flow injectors (not sure what cc yet)
Head is being ported and polished.

Have any of you guys got any comments on this motor? In the Uk people are going 7.5:1 compression and 1.6 bar of boost. Can I keep the compression the same?
