Re: Converting Alfetta GTV from Spica to Bosch FI

["Obie Fayth" <bibendum59@xxxxxxxxxxx>]

Tom,
    At one point I was planning on doing something similar w/ my '78 
Alfetta GT. The only hangup I know of is that the intake ports in the bosch 
head where it meets the intake manifold have an extra cutout to accommodate 
the bosch fuel injectors. If you look at a bosch intake manifold gasket you 
will see that the ports are more egg shaped rather than roundish like the 
spica version. I was planning on modifying my spica head to match the bosch 
manifold, but this is something that should really only be done well with 
the head removed. You are probably better off just finding a good used bosch 
head.
    I was actually planning on using a bosch LH-Jetronic system and got as 
far as collecting a majority of the parts and info needed for such a 
conversion before other projects came up and the EFI as well as the rest of 
the projects related to the master plan for this car found themselves on 
long term hold.
    Depending on how much customizing you want to do you might want to 
check out TR Induction (I think that is the name) which manufactures some 
nice EFI conversion related parts that might let you use the spica manifold.
