My actuators are shot, and I'm wondering if it'd be possible to use the S4 system. I'd like to remove the air pump, but I'd like to keep the actuators. Not worth it? Not possible?

you mean to plumb it using exhaust? yep, basically you'd just take the feed line from the air pump (i believe its actually on the acv) and plumb it into the split air pipe

Yeah, sure. That'd work

If you are talking about actually using the S4 actuators, you'll have to use an S4 LIM. The air lines for the actuators actually go through the manifold. If you just need new actuators, I'm pretty sure I have a pair of the S5 actuators that are in good shape.

Yeah, the vac. diagrams make it pretty clear. Activating that seems like a really simple task.
