Any other particular items you ordered and/or anything you'd do differently?

Ive never done the S4 intake. how hard is this job? I wouldnt even know where to start.
If i could, i would just bolt a euro S runner system on there
I want to pull mine off and do some porting of the intake and may the inlets to the intake ports on the heads.

Not that you will have that problem but when I put the silicon boots on the intake, it was such a major Pain in the **** to do, that I took 'em off for now as I'm still running NA. When I boost, I'll put them back on, with the wide intake and side plenums on the '85-'86.5, and since I'm pulling them a lot, I went back to stock boots till I have all my maintenance and upgrades done.

Mark- It's a little daunting- my buddy came over & saw it after I had it completely disassembled & said" It's a job not for the feint of heart"... I guess the most technically difficult part is simply accurately replacing all of the vacuum lines & hoses in proper order.Some nuts(esp.) the brake lines are tricky to get to on reassembly, as are the fuel rails& injectors. I sent my injectors out for rebuilding & flow testing while I was at it. Do as suggested by others in attaching the injectors to the rails first & then seating them into their respective holes.I took the MAF & throttle body off too for cleaning & lubing,as well as cleasing the intake tubes with brake cleaner& rags& some rope( as you would clean a gun bore). Make sure the throttle cable is routed around the pulley & operates without binding, too. Proper factory spec torquing & you're back in business.

Mark- Keep campaigning your Big Dog 928- I'm a fan of your race videos.

Or is the hose sufficiently resilient to accommodate the bends without collapsing?
All of mine are routed to an external breather rather than back into the intake, so I didn't stick with the tradition route. I got tired of drain the oil out of the plenums...
If you are sticking with the stock route then you might want the elbows, or call 'em and query the company ask to how well they would do in that situation.
As Ed would say YMMV...

Both said they can have them back to me by Friday. Need to get the rear U shaped fuel line rebuilt this week too. Hope to have it all mostly back together on Sunday(fingers crossed).

Update;
injectors cleaned by Cruzin performance,
replaced vacuum lines, oil breather and gas lines, cleaned throttle body and ICV. Painted intake tubes, intake plenum conectors were replaced by PO.
I was surprised how easily the injectors fit in compared to removal, I used a little vaseline which helped I'm sure.
Everything is all connected and ready to go
I need to instal the battery first.
Question: what is the best way to prime the gas hoses and fuel injection rails? I want to ensure there are no leaks before it starts up.
I'm very excited to turn the key but also apprehensive about a no start condition or running rough. The wiring felt hard with litte flexiblilty.
I worked long and hard, my first project but not my last. TB/WP next.

Great, airbox not in yet, I can remove side plenums and view injectors with mirror. With fuel relay removed what connection need jumping? Do I need igniton switched to "on" positon?
The fuel return lines will purge the air in system?
