Just wondering how much power can be extracted from an rb26 with stock internals? I have transplanted the motor from an r33 v spec into my r33 gtst, currently running 383rwhp on 18psi. Is this a usual result for the following mods?
-Power fc
-modified dump pipes and custom 3 inch
-ARE front mount
-I have been told that the turbos are from an N1 gtr. (steel wheels?)
Thanks in advance.
