RE: [alfa] EFI and Spica

["Thomas Moll" <moltek@xxxxxxxxxxx>]

Stefano,

Don't know if this is true for the Alfa twin spark but the engine in my
Swedish market 1985 Ford Sierra had a smog pump and air injector rail from
the factory. Maybe there is a certain vintage of the Alfa twin spark that
came similarly equipped.

Anyone in Europe with knowledge of such?

I've realized this too, and I'm counting on this to put a twin spark in my
Alfetta. With two blown head gaskets in three years, I'm not in the mood to
do it again when I can put the much talked about engine in - especially
since it should be easier in an Alfetta than a GTV. The twin spark exhaust
manifold could be used with no problems.

There is one hurdle I think about often and have come up with a possible
solution. It's the smog pump and air rail. This item is on the list of
things to check, so it must be in place.
This is a 79 California Alfetta. No way around this until 2009.

I've been thinking to weld a mock up air rail, remove the vanes from the
pump, and mount the pump. There are other makes that used a pump and have a
more straight forward pulley than the toothed pulley of the Spica cars. Some
of the cars have it mounted with a bracket like the alternator, so I don't
think it will be too much of a headache to mount it. I don't think actually
tapping the manifolds is necessary since the engine is much cleaner than the
Spica ones.

The catalytic converter and stove pipe are easy to install, so I'm not
worried about them. In fact the stove pipe is often overlooked anyway. I
plan on thinking this through some more and looking for an engine later this
fall. Comments on this are, of course, welcome.
