Jakes correct...stock AFM..S hose just moved to a differnt direction..The
pressure side runs back by the coolant bottle and arond by the air cleaner..
I just cut the exh pipe fron the collector to the cat and routed it up to
the turbo...10 minutes and I can have it all back to the stock
configuration.
So far the mixture has seemed OK as it sits..I do have an additional
injector setup, but haven't needed it.
The oil feed comes fron the oil press swx by the pulley via a T and the
return goes down to the oill filler tube bottom. I did it all when the eng
was out. I got this van as a basket case and it had a fresh eng sitting
there, so I said to myself...Self...why not put a turbo on it...
So far so good...Daryl

The injectors supply fuel at the request of the Air Flow Meter: so more air,
more fuel. The oxygen sensor adds its second opinion after the fact and all
is well.
A turbo or supercharged motor makes more power because it is being stuffed
with more than its natural capacity of mixture . At 5psi of boost, Darryl's
motor is using 30% more air, the equivalent of a 2.7 litre or so.
