Cga3 into cg10de coilpack

Hello everyone.
I have a 2002 cg10de coilpack and have sourced a cga3 engine. I understand it will fit the cg10de gearbox and work with current t standard ECU. Will the alternator and starter and throttle bits work from cg10 or do I need to get the cga3 parts and use them.

Thank you for your help guys.
