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
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?
Just a project/novelty value really - something to do in the evenings other than sit on the computer!!!) Don't want mad gains but something
useable (and that can keep up with my 'busa in a straight line - Triumph far quicker on the twisty stuff anyway ). Another 20 - 30 bhp I
guess and more torque will never go amiss.
If you're selling let me know how much you want (and postage to west Kent) via u2u please.
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
