What's special about 200hp?
You can squeeze ~180hp out of the o.e T2, which, at the boost level you'd be running, would give around 200 'torques' [/Clarkson] - That'll make for a great road car (read driveability) than fitting a larger blower with its laggy response nature.
Track usage is a different kettle of fish of course...maybe, but chasing numbers just for pub bragging rights is craaazy dog [/Westwood].
If that's the case, aim for 230-240hp as that's 'easily' achievable, and shouldn't hurt the wallet too much in the process.
Imho.
