Yeah, don't get me wrong, you won't beat them for response and the unbelievable shove you can get, but they are problematic, I mean, just look at the problems I had when I first did it, I think the turbo came off at least 7 times in the initial setup, admittedly I knew no one else who'd done it, so I really was flying by the seat of my pants, but they are fiddly...
If you need a fit and forget conversion - something you can simply install and drive to work on monday - seriously look into Wastegated GT series... But just don't assume they're a T2 and de-wastegate them, they will blow themselves up if you de-wastegate...
If you do have your heart set on a VNT - 2052s are plentiful and cheap, you'll see a very reliable 170hp with the unbelievable torque that goes with, you'd be significantly faster real life than a 180-190hp TD04 turbo'd car... 2056s are normally early generation ones and with that size compressor on a small turbine, you'll see high exh. manifold pressures and surging very quickly - you probably wouldn't get much more out of a Gen 1 2056 than you would a 2052... 2256s are a damned good option, but prices are very variable, they came on *30d BMWs which lunch their turbos regularly, so can be expensive...
However if you fancy something that is VERY driveable, isn't horrifically powerful, but will give you an incredibly flat, linear response - a late generation 1749VA is a great option, they see 190hp or so... You may even find you can pick up a GTB1756VK for cheap, they'd be a great piece of kit on an XUD for a low down torquey engine, but after hearing you talk about VTEC engines, you're probably of the revving type, in which case, a TD04 or Wastegater GT series is probably your best bet!
