Man.. I wish I would have asked before purchasing/installing it.
I would like to know little more in detail if you could elaborate though. I would think "flows less" mean that the impellers are smaller given same rpm between s13/14 engines, wouldn't that cause less cavitation? unless there's something going on inside the block.. or if the blade design is different.well, let me know! I will change back to s13 water pump if I have to!
I do have bigger pulley so hope that it helps. I will report back after next track day!
