Hi Paul,

    Here are several photos of my new intake system (still in the works as
you can see).  Decided to try using thin wall (.058) tubing rather than
pipe. Have 1 1/2" OD tube for primary and 1 5/8"  OD for secondary.
Decided to use a flange that bolts to your casting just incase I wanted to
try something different (or screwed up the tubing).

I  enlarged the inner ports a bit for my 1 1/2" tube and moved the position
down a bit to preserve the thickness of outer wall of the casting.  The 1
5/8" tubes stuck right into the casting's secondary ports.

I tried a 3/16" flange (seen in photos) but, decided that it had too much
flex so have upgraded to 3/8" flange.   Decided to mount the injectors low
in my newly redesigned throttle body plenumn (more on that later).  One
photo is of my test attempt of brazing tubing to flange.  Worked fine on the
3/16" thick flange.  Beat the heck out of the tubing and while it distored
under the blows, the braze did not break.  I used a new "2nd" generation
brazing/soldering rod that requires no flux and is the easiest to use by
far.

As you can see, plenty of room for the turbo to see on top of its manifold
thanks to your low profile casting.

P.S have not forgotten about the data collection.  Had to reorder the GPS
cable from Garmin as mine turned out to have a defect.  Should be in
shortly.

I was wondering when someone would try the flange :) Good idea but
extra work of course. I busted my buns trying to get that manifold
in there between the stock turbo and the block :)

Sorry about the bolt hole breakouts. Looks like you will need
small aluminum blocks tig welded on in those areas
adjacent to those bolt holes. Fixed on the next batch.
