Well.
You can always use the 440's from your old engine on the new one and put he AFM back on, therefore the ECU thinks it's a ST185. You'll get some benefit of the better cam profiles from the ST205 engine, but your T-VIS will go all funny - because it's not there anymore.
Right now I'm doing exactly the same thing as you but on a MR2, but I have a PowerFC ECU and it's already running map, the lack of T-VIS and cam profiles alone is making revving the engine on moderate throttle all funny since the ECU is tuned for the old engine but with 540cc injectors already.
Good luck.
