I have two exhaust mainfolds for S4 TII. One has a couple of cracks (the one which came off the engine in my AE) and one doesn't. The only *other* difference I can see is that the Switching Actuator is on the opposite side of the Turbo Inlet. (see pic)

I would like to use the crack-free manifold, and wonder if I also change the pipe which feeds vacuum (to make it reach the vacuum spider) it should work okay, right? The existing vacuum line is about 3ft long and reaches from the spider on the back of the UIM around to the front under the turbo air intake.
The manifold with the reversed Switching Actuator has a vacuum pipe about 1ft long and it seems to me that would be a better idea anyway.

So, whadya think? Good idea or not?

hmm one of those is a 929 part! um i'd think the iron bit is the same, so either swap all the actuator crap over, or do like you say and change the vacuum pipe too.

929 part? Which one, and what is 929 part? I'm clued out; explanation would be appreciated.

The manifold assembly (in pic) - which includes the switching actuator, levers 'nstuff is what I was planning to swap, so the only other thing is the vacuum pipe. So, your take is this would be okay to swap?

mazda put the 13bt into the 929 sedan in the rest of the world. so a couple things are different, like the engine mounts, oil pan, the turbo actuator.

so if you wanna swap the whole thing, i don't see why it wouldn't be fine

Ah. Thanks for that. I no absolutely nothing about Mazda cars outside the RX.

I appreciate your thumbs up on the idea. moving ahead.

One question, do you think it'd be easier to install the manifold and turbo as an assembly, or installing each unit separately. It appears it might be a tad easier to get the turbo inlet bolts tight enough when the mainfold is on the bench.

Thoughts?

never mind. stupid idea. both of those iron monoliths together are way too much weight to wiggle into place. didn't even have to try it, just heft them together, one in each hand.

sorry to make such a bone-head remark.
