I had this same type of kit on my ls/vtec a couple years and spooled by 3300rpm. it's all brand new.. turbo even still has plugs in it. It's just out of the box.How long does it take to spool up? Does it have a lot of shaft play? Does it leak at all? I'd trust godspeed over a typical ebay turbo but if his is doing fine, I might consider it :roll:
