Well it all depends on what you want, i have a VF34 on mine and they are supposed to be good for about 350bhp, on mine with a full decat & Harvey Smith headers i'm getting 336bhp and it starts to spool up from about 2500rpm and by about 3300rpm i'm getting full boost. []
The TD05 comes in various models (18G & 20G being the most popular) which i think are good for upto 400bhp, these turbos will spool up later but have a bigger hit as long as your engine can take it.
With your setup i would stick with the VF34 unless you intend to go for any other major mods (ie stronger engine internals - stronger gearbox etc)
