As far as ICs, you can piece your own like I did but it's a PITA. I did it and I know I'm going to have to replace it eventually. Had I spent the $$ on an FC specific kit I'd be done with it now. Just letting you know.
I'm trying to get my BNR turbo swap going so I can't tell anything yet but a lot of members are having great success with all stages (even though they seem to all hit 300 hp).
