3.4l 996 intake manifold on 3.2S motor

looking to install a 3.4 intake manifold in my 3.2 equipped boxster.

I have the 987 airbox and maf, 996 throttle body, and customer intake tube already, so I'd like to put on the 3.4 manifolds. Also have 987 engine cover for more clearance.

I think I understand the necessary steps, but correct me if I'm wrong:

1. Aluminum lower runners required
2. Plastic upper plenums
3. Fuel rail from a 996. Is this correct?


1. Drill and tap holes in heads
2. run shifter cables under plenums
3. ??????

Any other tips or parts necessary?
