His turbos have 9 blades on the exhaust side, same as in the picture. He even has tubular exhaust manifold and his Z had big lag but big power also. gt28r have 11 blades which are more restrictive but provade sooner spool up, gt28rs have 9 blades which let exhaust flow better and requires more velocity of the exhaust to spool the turbos than 11 blade. 9 blade turbo has more power and lag. 11 blade has good power and lag very close to stock. $850 local garrett here in phoenix sells them. and $600 for gt28r. I whanted to go for gt28rs but compressor housing type made me sway more to gt28r.
