JDM Twinscroll/JDM STi vs UK STi Engine
After a crank failure recently in my V5 STi classic i decided to replace the bottom end with a stronger newage STi version,i managed to secure a 21k low mileage JDM twinscroll STi 8/9 bottom end from a friend of mine.i have read that the twinscroll engine has differences to the JDM and UK STi engines,does anyone know what the actual differences are and possible benifits/disadvantages of a twinscroll engine.

AFAIK the JDM twinscrolls also have a different turbo (VF37?) and downpipe, and as a result faster spool up and better top end performance. Can't say this for certain though as I'm not an engine specialist.
Bottom end - not sure of the differences if any, as per H4RDY's post.
Suspect Midlife or Splitpin would be able to tell you, or David @ API to name a few names.
