B20A9 / B20A7 Tuning parts question

[GermanB20A9]

I´m searching for tuning parts for the Ba20A7 or B20A9 engine.

My questions are,

1. Which underdrive crank from another Honda fit?

2. How can I get the Fidanza Flying wheel, it´s official sold out?

3. Did the camshafts drom the Integra realy fits?

4. Which Intake manifold from another Honda Modell fits?

 

 

Thank you for answering my questions, I know it´s a lot spezial.
