Swapping '90 Motor into '87 Chassis N/A
Okay, well it's come down to the final days.
I was wondering how people routed the vacum hoses and got the 6 ports working. If someone has done this swap I'd love to hear problems and solutions you encountered.
I'm getting a rpm switch for the VDI
It's set in stone that I'm keeping the S4 ECU, wiring, thottlebody, and OMP (obviously).
Any tips on routing the ACV vac hoses to the FPR?

Well, I've done the swap, but didn't keep a single piece of smog equipment, so I can't help..
I can tell you that the 89 runs just fine the way you are going about it though, I have the same setup (sans smog of course)

Cool! Well thats good, I'm using the S4 front cover and water pump. It's just the damn Vac lines.
How did you get around the fuel pressure regulator issue with the vac lines going to that from the manifold pressure to atmosphere pressure form the ACV to the Fuel pressure regulator?

Plugged the Fuel pressure vac inlet 
Sends it into high pressure all the time. Not something you can get away with on a street car, but my car, aside from warmup, spends all of it's time between 4000-8000 RPM.
