Hey Duke! Sorry, man, carbs or injected, it is an Italian Sports Car, it will NEVER, EVER be a sleeper. The front end looks like a Porsche and the rear end a Ferrari, never, ever be a sleeper. A sleeper is stretching the fenders on a GEO Metro and stuffing in a 400-500hp Chevy 350 with tubbed 12 bolt rear end and powerglide transmission, that is a sleeper, no one would ever see that one coming!

SPICA to carbs? OK, I guess.
Bosch to carbs? Completely and totally stoopid.

Joe,

Great comment regarding converting to carbs. Just so happened in the summer of 1969 I passed on a trip to Woodstock but did take up an offer to go water skiing for the day with family friends and did just that - POKED STICKS INTO HORNETS NEST. Ended up I was allergic to the pesky buggers and gave me a 4F deferment from the Vietnam war and changed me life for sure.

Sorry, back to the post. A few years ago I was looking for a project and came across a 1985 spider with 12k original miles, no rust. The only problem the car was swallowed up in the Hurricane Sandy storm surge and was in the Atlantic ocean for a while. I know, I know .....

The Bosch injection system was kicking my a** for quite a while, now with 2 rebuild Webers I will hopefully salvage some seat time this summer. I have a new (pre injection) distributor and will be praying alot. The pistons were seized in the liners so we have new in that department. cams are stock, but we have a pair of Columbo/Barini that may get called into service.

How crazy can this conversion be?

for Erik, different states may have different regulations here in the US...as for Texas, anything over 25 years of age, doesn't need to conform...

California seems to be the most likely state to have problems w such changes, BUT my car came from California ,its a 74, and previous owner had already converted to Dellorto carburators from SPICA....which I like, ...so it does seem even there its ok....

for Frek....you are doing molto bene parla Inglese!

me, Swedish , but with French /Italian ancestry...plus married to a Colombian and living in Texas , so I mix up quite a bit! my Spanglish is better than my Italian , but my SwEnglish is better... also , eine kleine Deutcsh, et un peu Francois....LOL

Has anyone noticed that this thread is ten years old?

Bjorn: Here in California, pre-1976 cars are smog exempt, so you can get away with converting a '74 from Spica to Dellorto (it is probably illegal, but there's no enforcement).

However, converting a Bosch EFI -era car to carbs would result in a massive fail at the biennial smog inspection.

didn't look as it popped up as "new"...LOL

ok...but here in Texas, no smog check on cars over 25 yrs old, so this year everything older than 1992 model year are exempt as "classic or antique "....cant imagine a 1991 car being considered a classic...LOL

Since this is a zombie thread I don't mine taking it off topic a little. I've always found this to be a goofy notion. People have some arbitrary year in their head (which tends to vary by year of birth) that is an imaginary dividing line. Any car made after that year can never be a "classic", even 100 years from now.

When I was a teenager in the late '80s anything "interesting" produced before 1970 was considered a "classic" even though they were only around 20 years old. For many people that year or something close to it still remains. Forget the fact that a '91 Spider is 26 years old now and essentially the same car as a '71 except for the addition of power steering, a body kit and some frame reinforcing. Instead remember what Bjorn is saying that an E30 M3 can never be a classic, a Ferrari F40 can never be a classic, a Porsche 959 can never be a classic. Maybe an early Porsche 930 could be but certainly not a later one. It's just a silly attitude.

I am a S-2 Spica Spider owner and wonder how much fiddling are required if I were to convert to Carbs? By fiddling, I mean annual fiddling with the carbs. I realize that this would permit European cams but also require replacement of the exhaust manifold with a headers set up for optimal performance gain. Is it worth all the messing around? The solex carb I have on my 101.23 1600 never needs any attention.

The carburetors on the '78 Spider and the Sprint GT have required very little annual "fiddling" once properly set up.

Whether or not it is worth the effort depends on your objectives. Carburetors, good cams with a modern lobe design, and a two piece exhaust manifold are fairly low effort modifications that will make a noticeable difference in power. If you decide to proceed, I suggest better cams than the 10548, if that's what you mean by european cams. BTW, I am reasonably certain others have used the 10548 cams in their stock Spica cars without issues.
