While it would be a good choice, the C900 has a T3 flange, not a T25 flange, so it will not bolt right up. You would need an adapter plate, which would mean new oil supply and drain lines (since the turbo would shift, and the coolant lines are probably long enough to bend to the right position,) or you would need to have a custom exhaust manifold made with the T25 flange, which is pretty money, but does make a big improvement.
I have equal length headers on my tuned C900T with a TD-04 15T from a 9000 Aero on it, and it is awesome, but we did all the fabrication ourselves, so the different flange was not a very big deal, but since I don't know what equipment and/or friends you have access to, there are options just as good to be had with T3 architecture, so they will more or less bolt right up.
Just curious, have you done any of the supporting modifications already, fuel (ECU, or RRFPR or 3.0BAR FPR, larger injectors), 2.1L head, 3" downpipe, front mount intercooler, etc, as these are needed to appreciate the potential that the new turbo will bring.
There are lots of discussions on turbos, if you search last threads, and I would be wary buying turbos from eBay without talking to someone about it who knows the C900 application for a while first. There are some excellent and very affordable alternatives.
Good Luck,
Best,
Drew
