You planning on getting 6 speed upgrade?Any decent turbo upgrade on 2,5 will tear apart ever single 5 speed box (if it isnt ppg offcourse).
I would stick to current setup(maybe go vf43 and remap to reach 330+) untill you have funds to do whole job

Getting a turbo which wont destroy the unforged engine, but will do justice to it once it is forged (assuming your doing the supporting mods like the gearbox at the same time) might be tricky!
An SC36 or 40 on a 2.5 would have bonkers spool, but the higher revs might overspool it. It would map conservatively onto the standard engine, but once forged, a spicyer map and some meths would see you above 400bhp.
As said though, getting the turbo compromise right for something that will suit both power levels isnt that straight forward! You might just want to pocket the cash for now and do it when the engine is built for it, that way youll get the turbo that best suits your engine and drivetrain.
One all to common mistake people make is concentrating on pub numbers rather than drivability and torque! A spooly 350bhp will be a much more satisfying and real world quicker car than a top end 450bhp. And if your on a tight budget, and buy a turbo with bhp in mind, chances are youll buy something which trades power for lag and kills your road manners and drivability.
