I have 1 S15 Spec R full metal blade Ball bearing turbo. They are in slightly used condition and came from a S15 front clip that had around 8000 km on it. This turbo has no shaft play at all. The turbo comes without the waste gate actuator and comes with the turbo inlet pipe and also the intercooler outlet pipe. They are perfect bolt on upgrade for S13/14 SR20s or CA18DETs. Great responses with minimum lag. They are rated for 320hp. The compressor housing is AR60 and exhaust housing is AR64. Thy are pretty much the same spec as N1 or maybe GT2530 turbo in the SR20/CA18 form. The price is 650obo and Shipping can be arranged on top of the cost of the turbo.
Here are the pics
The divider between the turbine wheel and wastegate proof that it is not a lesser spec S14 turbo or S15 spec S turbo that is not BB and ceramic wheel.
