What can you tell me about the 74mm TB?

Ha, I was the one that told the other guy about you!

I'm not sure the 996 guys suffer failures often, but they do. I'm not 100% positive that's my problem but its very similar to what happened last time.

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?

Thanks, but here is the issue. This is the IPD 996t plenum I couldn't find the oem pic...but this is what the vacuum stuff needs to resemble.
