Interesting layout.  I spent some time noodling with the 20B manifold
tonight to see how I would eventually route everything.  I like your
arrangement.  How do you plan to connect all the tubing, including the
"sockets" for the injectors?  This looks like a good candidate for some

MIG

or TIG welding.

The tubing will be tig welded together. Where is goes into the sockets
Tracy's JB Weld could be used.

And what about those injector sockets?  Any ideas on how to make them?

What

will the fuel rail bolt to?  Heck, why don't you just send me all the
intimate details so I can rip them off carte blanche?  ;-)

I figured I would have an injector block machined from an aluminum plate
that would receive the runners into sockets on either side (or maybe

just

pass them through and leave a drilled hole for the injectors... then

seal

weld the runners them to the plate).  The plate would provide bolting
locations for the rail.  At the starting end, I would just have a larger
plenum coming from the intercooler.

The injector sockets will be turned on a lathe and tig welded to the tubes
using an alignment jig to keep them parallel and in line. Then drilled out
so the fuel can get into the tubes. The fuel rail will be made from
half inch square steel tubing and some sort of clip welded to the tubes to
hold the injectors in. Also raw extruded aluminum fuel rail can be bought

and

drilled for your injector spacing.

If your feeling chipper you could make a pattern and cast something for
this end of the manifold as well :-)

I would definitely consider it.  Heck, it's got to be easier than those
curvy core boxes I had to make for the manifold!  But unless I can get wall
thicknesses way down, the darned thing would weigh much too much.  Keep the
cores/bores straight, and I could definitely pound out something.

I'll give it some thought Tom.
