Ahh Larry step up to the plate.
Although having never turbo'd an alpine, I myself have fuel injected
one.
I can tell you that using an OEM fuel management system is just about
as impractical as you can get.
All engines behave differently "especially heavily modified, or turbo'd"
and thus the control strategy, which is in the form of firmware, will
vary considerably.
There have been companies that have and possibly still do sell
GM ECU's originally used in fieros and other 4 bangers. These
systems generally required that you range "jet" the system by
altering the fuel rail pressure, or by buying the correct lb/hr
injectors.
This strategy works well generally at two points, Idle and WOT
but not so well in between, where mapping is of great interest.
If you are willing to shell out about a grand for an ECU,
electromotive makes a decent one that includes crank triggered
ignition as well as fuel control, which is tweaked via a laptop
computer and serial interface.
Me, I didnt have a $1000 burning a hole in my pocket, so
I built my own ECU.
I will say this though,
having run every possible stock intake and carb configuration on
alpines, as well as dual twin choke webers, there is absolutely no
comparison to the drivability and low end torque you get with a
simple EFI system.
The webers make more BHP, but are not very civilized until
the choke velocity is high enough to run the main circuit.
If you are interested in a lower $$$ ECU, drop me a line.
I just happen to be developing one for a forklift engine
that might fit the bill.

Since I am building the world's fastest Sunbeam using twin turbos on a smal
block Ford, I got to wondering if anyone out there had updated their 'pines
with a turbo? It would seem that installing the EFI and ignition from any
of the 4 bangers and adding a small turbo (T03) from say an 84/85 T-bird
would make an absolute screamer. And it would start easier and for sure
give every known Tiger a run for their money (and I own a Tiger). Just for
instance, I purchased my two turbos for 200 bucks, total. Get the EFI and
ignition from say an Escort or something with a slightly larger motor,
modify the intake for the injectors, add pertronic trigger in distributor,
etc. Seems easy...but probably isn't. Also, those turbos I mentioned are
but 1 of many but these have water cooled bearings. I wouldn't mind
assisting on such a project either by e-mail or hands on if close enough to
where I live...
