Looking for turbo and induction solution

[Ben Swann]

After solving long drawn out problem with fuel  delivery in my '83 UrQ using Megasquirt
EFI, etc. I now am finding issues when developing boost.  After hard run up to
Four-rings gathering:
http://www.justfourrings.com/phpBB2/viewtopic.php?t=935&postdays=0&postorder=desc&start=
0  and spirited mountain driving there was a noted progressive power loss with boost not
developing fully.  I had good boost and nice jet engine sound going up and hitting
continued 2.5+ bar, until a noticable sound like tubine blades rubbing on something
whirring sound entered into the picture.  I also noticed more oil blow, but may or may
not be related as some was coming out of the oil cap.

I think the k24 is dying - sounds OK when cold, but after 2 or three accelerations has
hard time making boost and that becomes associated with blade noise.  I did not find
anything injested, and so assume bearings are going south.  I have a few turbos and am
contemplating installing nice 26 rebuild I have so I don't have to change oil and water
feed lines.  If I do I'd like to see if there is a more sane way to do intake,
intercooler pluming routing.    Latest setup had starigh hose into turbo with cone
filter, and final test with no filter still had whirring noise.

There is pretty much an open air tract into turbo with just a cone filter and blowoff
valve - just the close proximity of the outlet hose makes for difficult plumbing and I
think going with slightly larger k26 intake and outlet will  be problematic with hoses
barely fitting on the turbo since the intercooler outlet crams right next to the inlet
of the turbo.  This is still pretty much stock orientation - one of the things that
really did not change with all the mods is the intercooler and turbo setup.

If I have to pull bumper off and go through turbo swap, just getting ideas what might be
a good approach to having a good intake solution if any.  Possible FMC in grille or
reworked intercooler that gives more clearance near alternator would help.  There is
much more room her than with CIS, but still things are very tight right at the turbo.
It seemed that there may even be a way to bring intake to turbo through the bumper as
there is a straight shot in there - anyone done this with some sort of filter system
located in the bumper with perhaps force air dam below.  

Pictures and ideas of tried solutions would be helpful.
