Alright guys just wanted to ask a quick one before purchasing an S15 Spec-R turbo. I have a stock SR T25 and a little CA T25 and I was spinning the turbine with my fingers. What seemed strange to me was that the ease of spin was about the same with the S15 turbo. Now I know both turbos have bearings but I was under the impression that a "ball bearing" turbo would have spun considerably easier making it more efficient. I compared a buddy's "non-ball bearing" aftermarket turbo and it spins for a few seconds after I introduce a force. So what im asking is should the S15 "ball bearing" or any ball bearing turbo for that matter spin freely with ease or is it just the difference between these stock turbos vs aftermarket?
