What can you tell me about the 74mm TB?

The 996 turbo part number is the same as the 986 part number.

They are all the same. Sadly on the 996 turbo, the plenum is very different from any of the NA motors, so it's not as simple as buying the 997 plenum for 50 bucks!

Gotta buy the stupid IPD for 900. Even at big hp levels the plenum/TB combo is "said" to make 20 to 30 whp. And THAT is for guys pushing 700 to 900 hp.

I have a hard time thinking it would be anywhere near that for the NA folks, but like I said I don't know.

I don't know much about the turbo plenums, but what about this one?

Pretty sure that's for a 74mm tb isn't it?
