My friend has got a '94 3.6 turbo, european market.
He can't figure out the routing for engine vacuum hoses, so he's looking for a diagram.

Like this one.


Can any one help?
Thanks!

Yay! Thanks a lot man!

Where did it come from?

Metal Guru

The Factory Service Manual.

The one like this?



Just wondering if it's worth getting.

Well, this scheme doesn't work on the 3.6 turbo. At least on european ones.
It's got few other vacuum valves.
So I wonder if there are any other 3.6 turbo vacuum diagrams.

Metal Guru

Don't see how that can be. Only one version of the engine was produced worldwide to my knowledge.

Is that the diagram that you used when rebuilding yours? And does it come from the "964 3.6 turbo" manual?

Well, I don't have any of the air injection spaghetti on mine any longer. That alone accounts for more than 50% of the lines. But it makes no difference as the emissions hoses are identical between the 3.3 and 3.6. FWIW, my manual spans all models of Turbo. What's different about the two are things like injectors, wur and fuel head.
Porsche carried CIS over to these cars to save on engineering manpower and cash (they were nearly bankrupt then). Not having to re-certify a new system for emissions was the goal so they could invest in the development in the 993. Therefore the only changes for the 3.6 were to individual fuel delivery components.
Post some pictures of what is left over and trace them back to their source.
