So I've been reading about the JB-DET engine in the L880K Copen and I have learned the following: -JB-DET is basically just a updated JB-JL -JC-DET is basically just a bored up JB-JL -The JB-DET has a turbo and intercooler -On some cars the JB-DET's intercooler is mounted on top of the engine and in others its mounted in front of the engine. -I read that the Copen has a twin scroll turbo instead of the regular turbo found on other JB-DET's. This explains why the Copen makes peak torque a little earlier than other JB-DET powered cars. But now I have these questions: -Is the UK Copen also equipped with the same twin scroll turbo? -How do I know I'm not buying a regular turbo and not the correct twin scroll type (assuming the UK Copen uses the twin scroll type) if I were to have to buy a new turbo (hopefully I will never need to, knock on wood) Reason for that question is: -The UK Copen makes slightly more power but slightly less torque and has slightly fewer rpms compared with JDM Copen.
I believe the uk version just has some different electronics, I assume it was just for emissions reasons. I doubt you'd pick the difference on the road.
