This message might sound sarcastic, its just my writing
style... I'm going though this step by step so you can
follow me thoughts, and in reality, so I can follow my
thoughts too <G>.

Lets draw a V6 engine here, looking at the top of the engine
(intake), with the fan belts to the left, and the bell
housing to the right:

	2   4   6

	1   3   5

Good drawing, eh? <grin>.  Anyway, lets connect a headers to
the odd banks to a turbo, and another header to the even
banks to a turbo.

	/---/---/---(T)
	2   4   6

	1   3   5
	\---\---\---(T)

If the firing order is 1-2-3-4-5-6 then each turbo receives
and alternating pulse.  If the firing order is 1-3-5-2-4-6
they don't.  That was all I was saying.

The buick V6 firing order is 1-6-5-4-3-2, therefore there
would be no need for 180 degree headers, i.e. crossing over
exhaust tubes based on these pictures.

Now I'm really curious.
