Engine Out - 996 Intake or Any Performance Mods I Should Consider Now?

[nuvolari]

So, my engine is out and getting ready to get back on the project and just wondering what performance mods I should do while engine is out? I've read good things about the 996 intake manifold but I haven't seen any threads about the full process including a complete list of parts needed and all that needs to be done. If anyone knows of a thread or has done the mod, I would love more details about it especially a list of parts. I know I need the runners and associated parts plus a 74mm plenum but I believe there are also lower intake runners that are separate, correct?

My engine is a 2000 3.2L M96.21, so which 996 manifold do I need? I know 3.4 works but is that the only one? Part number?

Also, I would be interested in any other "easy" and relatively inexpensive mod to do while engine is out.

Many thanks.
