Someone(s) talk me into or out of SPICA!

I am in the early stages of converting my 1300TI Giulia to a 2.0L. I have obtained a 2L core, and it is a SPICA motor. The throttle bodies are present, but the pump is not. I'm now deciding which direction I want to head in terms of intake...Dual carbs...or SPICA?

I love the mechanical nature of the SPICA system...but what does it have to offer over dual carbs?

Cost? I know a Wes Igram pump will cost me well over a grand (or double that depending) But what pump? What else is involved besides the pump, throttle bodies and the associated lines?
A good dual crab set up with cost upwards of a gram as well when all is said and done.

decisions, decisions!

For a ti, carbs make sense. Both for general simplicity as well as ease of construction.

The Spica system requires a fuel return line to the tank, and a new port in the tank. Different fuel pump at the rear, special fuel filter, pressure idiot light and sender, etc.

65 Sprint GT (2nd Alfa, $500 daily driver)
102 Sprint (never did anything with it, but wish I had)
74 Berlina (first new car - now certainly rusted into oblivion)
61 Giulietta Spider G-Prod Race Car (where is it now?)
84 Spider Veloce (rarely drove it, so sold it)
86 Quadrifoglio (Dull car - no more 115s for me)
1971 Montreal "The Full Monty". Fair winds and following seas

Current Alfas
59 102 Touring Roadster - restoration complete, enough Alfa for any rational man. Or irrational, for that matter
Oops. Add to the "present" list, 10204 01488, 2000 Touring Roadster project

And past...
Two 1946 Stampe SV4C (c/n 294 "Rocinante" - wife's favorite airplane. RIP), and c/n 235 "La Bon Temps Femme" (gone to a new home, but never forgotten)

1946 Luscombe 8A
Starduster Too (recently spotted at the Nevada City, CA airport - over 20 years and an entire continent separating it from our stewardship in Binghamton, NY)
1955 Cessna 170B (wife taught me to fly tailwheel in this)

And present...
64 Mooney M20E ("Rambo". My faithful steed for over 40 years) Over 55 years old, and just returned from a trip to Argentina in him
Newest in the fleet

Right! There are a lot of ancillary components necessary for Spica besides the pump. And, you would have to mount them on your TI body, as well as acquire them.

Wes Ingram will charge ~ a grand to rebuild a spica pump. But you have to buy the pump first, and rebuildable pumps are pricey. Oh, and don't forget the thermostatic actuator - again, a costly item. So if you have nothing but the intake manifold + throttle bodies, acquiring the rest of the Spica set-up, and having the pump rebuilt, could easily run in the $2K + range.

As you say, a Weber manifold, two carbs, and linkage don't come cheap either. Centerline charges $2,150 for these parts (which are currently out of stock). You might be able to acquire the parts for less from BB sellers, ebay, etc., but not much less.

Still, going with carburetors rather than Spica injection probably makes sense in your situation.

My son now owns my '74 gtv. He switched it to Webers from my original Spica FI. It's a better car at the track now than when I had it. We live at sea level basically. I do know when he goes up in elevation...unless he wants to get out and switch jets it's a problem. I'm putting a 2L into my 1750...a bearing went bad on the 1750 crank...it will have a performance Wes Ingram Spica. It will be good at the track and at Mammoth. If you live where you have great elevation changes or like to go to places like that I'd make that a consideration in your thinking.

I'd suggest getting your pump to Wes with a significant lead time as he's pretty well backed up at the present time.

The passenger seat is 15 miles an hour faster than the drivers seat.

currently
2017 Giulia Q4
74 GTV restored daily driver
71 Berlina in 2L restored driver
the ones that got away:
1959 750 series Giulietta Spider Veloce
1962 Giulietta Spider normale
1965 Giulia Sprint normale
1972 GTV
1974 GTV
1974 GTV
1977 Spider
1974 Spider

Carburetors. I recommend against the Spica system in your configuration due to the plumbing changes needed to the fuel feed/return system as well as the filter system, as well as accelerator pedal system, etc, etc. And especially since you don't have a core pump to even rebuild. I'd recommend carbs with a change to some European spec cams.

If the Spica fuel pipes and injectors are still on the engine DO NOT throw them out. They have value.

I have a 1978 Spider with the Spica system intact. I'm parting the car out.

Tell me I'm sitting on a gold mine!! I need more money to pour into my 1978 with Webers....

I've owned both. I've worked on both. I've tuned both. I've driven both.

I'll take the Webers.
