Hi Gab,

And welcome!

Some books which may be of interest:
-Alfa Romeo Owner's Bible - Pat Braden
-Alfa Romeo All-Alloy Twin Cam Companion: 1954-1994 - Pat Braden
-The Alfa Romeo DOHC Engine High-Performance Manual - Jim Kartalamakis  (Jim also has a book on the V6)

I'm not getting into their accuracy or any other political rubbish about what mods work and which don't, but if you read these cover to cover and memorise every word, it'll give you a starting point to narrow down answers to some of your questions....  ;D

Note the Aussie spec Alfettas differ from the Euro and US spec cars in some obvious and not so obvious areas.

You can find these books second-hand.

I never mucked about with performance modifications but there is also a book in the Speed Pro series on modifying Weber and DellOrto carbs. If nothing else it'll point out where they are similar and where they differ.

I've never seen a Solex equipped Alfetta.

1.   RUST RUST RUST.  In my opinion the critical area is the base of the A-pillar/firewall junction (internal where you can't see it).  Major rust here is (almost) impossible to repair.  Rust elsewhere is no more or less difficult or expensive to repair than any other car.

2.   Depends what you intend to do with it but if originality is high on the list, know that interior and exterior trim parts are getting scarce.

3.   Mechanically I've always found the Alfetta to be robust.  But they are getting old and some parts are getting scarce.  However most of the main mechanical parts are available.  Transaxle synchros are a weak point.  Rear brakes are different, but not that hard to work on.  LSD was available in the 75 series cars which is where most Alfetta LSD are sourced.  I don't know that LSD was ever an option on new Alfettas. 

The Nord in-line 4cyl engines in the Alfetta 116 series are simply evolutions of those in the Giulia 105 series (evolved from the 750/101 Giulietta series (not to be confused with the 116 Giulietta model... :o)).  Some Alfetta engines had the pilot drilled in the crank the same as for the 105 cars, so can be retrofitted. 

As to retrofitability(?) of engine ancilliaries, it depends.....   Obviously carbs for 1600 won't work on a 2.0L engine.  There were also mechanical evolutions throughout the Alfetta's lifespan, plus different engine capacities.   There is nothing wrong with DellOrto carbs, though spare parts availability may be problematic.

The engine bay on an Alfetta sedan is identical to the bay on the coupes.  So except for bonnet clearance, the 2.5V6 can be made fit in the bay of a 4cyl Alfetta.  Later versions of the V6 come with added complications, but all readily achievable.

Personally, I don't know why you'd do it.  The GTV6 is likely to be the most common Alfetta in future, if it doesn't already hold that position.  The earlier cars were more susceptible to rust, are of course physically older, and people were less likely to spend money to keep them from the wrecker.  Therefore Alfetta sedans will, in future, be the rarest of the series, as has been the case historically (try finding a 750 series sedan...).  4cyl coupes likely to be second rarest.  This is effectively the opposite of the new sales figures for the different models.

It's easier to lust after a coupe, but takes true deep rooted love to maintain a sedan.....   ;)

As for non-Alfa engine conversions, the sky's the limit.  If you can make it fit in the engine bay, or mod the bay to accept it, any engine could be made to work, for a price (noting registration/engineering constraints).  Attaching a high speed propshaft to the transaxle is likely to be one of the simpler hurdles to overcome.

Thanks Festy, Now that steel bumper stamped 81 has been established, who has one and what number, there couldnt be that many.
Im interested to see the numbering and where they end.

I know these are up there for rarity but does somebody have or know of a GTV6 rear hatch not riddled with rust?

116 Series (Alfetta Sedan/GT/GTV & Giulietta Sedan) / a few Alfetta sedan questions
« Last post by MrGab250 on October 18, 2021, 05:43:02 PM »
G'day,  I've been looking at some Alfetta sedans as a project car because some of them seem fairly cheap. I've got a few questions though:

Firstly; what should I specifically be looking at with these cars, I know generally how to look at used cars, but is there anything in particular that goes wrong with these?

Second question: I realize that the rear brakes on these are mounted inboard. How hard is it to change brake pads and rotors? Are they available with an LSD?

And finally; how similar are these engines to the motors used in the 105 series cars? I realize that the crankshaft will be different; but what about things like carbys, distributors, camshafts etc? are they interchangeable?

Cheers, Gab
105/115 Series (105 Coupe/Spider/Berlina) / Some carby questions
« Last post by MrGab250 on October 18, 2021, 05:41:52 PM »
Hey, just a few questions about the carbys fitted to 105 series Alfa Romeos. I know these cars came with Weber, Dell`Orto or Solex Carbs. I've heard in many places that the Weber carbys are better, but just how bad are the others? I've heard some good things about the Dell`Ortos, but I've heard that the Solex carbs are not so good. Why is this?

Secondly, how different is the jetting between engine sizes? For example, if I was to use the carbs off a 1750 engine on a 2000 engine, how well could I expect it to run without changing jets?

Cheers, Gab
116 Series (Alfetta Sedan/GT/GTV & Giulietta Sedan) / Engine conversion?
« Last post by MrGab250 on October 18, 2021, 05:40:35 PM »
Hi, I'm wondering what if any engine conversions have been done to early Alfetta sedans with the rear Transaxle? I'm wondering if the V6 from the GTV6 will fit easily? What about some other engines? Wondering how you'd go connecting the engine to the rear trans axle.

Cheers, Gab
105/115 Series (105 Coupe/Spider/Berlina) / Some Alfa ignition questions
« Last post by MrGab250 on October 18, 2021, 05:39:16 PM »
Hi, I'm aware that Alfa Twin Cam motors had points and condenser ignition systems in 105 series cars, but I'm unsure about later cars, such as the Alfettas. I'm wondering if these had electronic ignition, otherwise, what are the other options for electronic ignition on these engines? I've heard a little bit about 123 ignition, what are they like? Are the twin point distributors that came in some of the GTA's worth while? or are they only for twin spark cylinder heads?

Cheers, Gab
