I have been researcing single turbo kits for a while and am leaning towards the Apex-i kit for the fast spool and responce, but all of the info that I have found has been with the RX-6A Turbo. I have searched the forum for a hard data comparison, but have found the information that I need. Does anyone have a dyno charts between the 2 turbo or compressor maps for the two turbos. Any info is appreciated.
