Ok, I bought a Triumph 955 Daytona for a winter hack and the winter is nearly over so will use other bike.
In the meantime, I've been thinking about turboing it for no other reason than I can but need to know about turbo sizing.
I'm thinking of buying a cheap Chinese turbo that is "suitable for engine sizes 1.6 to 2.5l". the Triumph engine is 955cc and spins
twice (10k rpm) as quick as lets say a 1600 crossflow, that puts the size at the lower end of suitability (and will boost higher up the rev
range?).
Agree or not or "it's more complicated than that" 
Cheers
Try a ct9 turbo that was fitted to a Glanza it was 1.3 so should do ok, good for around 220bhp

Maybe a TD04-16T? As fitted to some Volvos?
Depends if you want to keep the budget down and fit used, or even buy a new one but not have to pay loads...
Or C16 Rotrex instead?
Looking at Chinese things for around a £120 
I have no first hand experience of these but potentially they could be a bit poor quality. Or maybe variable quality would be a kinder thing to
say.
Personally I'd rather have an OEM quality turbo with eg 70k miles on it than a brand new Chinese one. But that's just my opinion.
Any turbo has the potential to sh#t itself but if we assume it's more likely with a cheap Chinese one bear in mind what could happen to your
engine if it's spits it's compressor wheel blades out...

Bike engines work well with surprisingly big turbos, look at most boosted Busas and they are running Gt30's and 35's.
On my R1 I charged I had a GT2556s on it,comes off some derv tractors as standard!
I had to use a 38mm external wastegate as the internal gate wasn't big enough and it was over boosting.
It spooled up lovely,and made the car totally different to drive as the torque was much higher.
But if I did it again I would go for a bigger turbo, I reckon a GT2860rs would be ideal.
I have a TF035 Subaru turbo here which is about the ideal size for a 1000cc bike engine if you want something ride able on the road, but it totally
depends on your power goals.
What are you actually aiming for? Driveability? All out power? Somewhere in between?
I guess you've also got to think of boost levels vs static compression vs turbo size etc

). Another 20 - 30 bhp I guess
and more torque will never go amiss. I ran a tf035 on my pinto, stock wastegate is 5psi, spools really quick, was a nice setup. I also accidentally once ran it at 18psi, everything
survived but it has cost me a fortune uprgrading everything so I can run that all the time
A cheap chinese turbo exploding vid is on yahoo, but I cant get the link to save for it
But I wouldn't want one to explode, in a car, let alone on a bike, and very near to your legs

Really? CT26 fitted to the Celica GT4 is barely capable of 250 (300 having its neck wrung) on the 2 litre 3sgte.

Thanks for the replies everyone, arrangements are being sort of made
