I've been having major oil consumption problems with my 360 ever since my prop strike, and subsequent engine overhaul, two years ago.  The problem is getting worse in spite of having had the cylinders removed and rehoned 3 months ago. 
 
I am pulling the engine off the plane this week to have the shop run it in their test cell.  They blame my set-up (electronic fuel injection and electronic ignition) and are refusing the honor the warranty or run it with the existing set-up.  I'm frustrated, because I never had any problems for the first 400 hours with this system, and it runs like a dream.
 
As a result, I am planning to, at least temporarily, convert to standard ignition and fuel injection.  This is a dreaded process and will take weeks of my time.  But I don't see any other way to get the problem resolved.
 
So... I need a bunch of stuff and a few answers:
 
1.  A while back someone posted or sent to me some information and/or pictures of an alternate air/ram air system that I liked.  It was, I believe, metallic, and had a spring loaded alternate air door as part of the "system".  It was designed to bolt to a forward facing servo and receive ram air.  It was a very nice looking piece of equipment made by a company that I think was in California.  Any information on this would be very helpful.
 
2.  I need the following parts.  Anyone who has any of these items for sale (or loan?) please contact me... I'm already dreading the bill for this problem so I am trying to avoid having to buy all the parts new.
 
    a.  fuel servo, spider and injectors (I'm looking at the Precision Airmotive kit.  I could use a carb, but then I'd need to address carb heat & control, etc...)
    b.  magnetos
    c.  mechanical fuel pump
    d.  electric fuel pump
    e.  mixture cable/knob/vernier
 
3.  Question - I currently use 2 high pressure bosch fuel pumps with a pressure regulator.  Can I continue to use this as the boost pump?  Or is it too high pressure?  A stupid question - how is a typical airplane (lyc 320/360) fuel pressure regulated when using the boost pump (or isn't it)?
 
Thanks for any and all help,
