Dual TBI units

[Shannen Durphey]

Take 2 early 2.5l tb's, mount them cross corners on a long runner
intake, and ya got crossfire.  The I's of the CFI flow different
amounts of fuel.  This has something to do with the regulator being
placed after the 2nd tb.  I think the injector sizes are in the
archives.
