Engine conversion?

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

The engine bay on an Alfetta sedan is identical to the bay on the coupes (and effectively the same as the 75 and 90).  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.

You can fit the busso 12v V6 into an Alfetta. Engine mounts and propshaft are different though and like me, you'll likely need to try source them from a donor GTV6, 75 or 90 that's been wrecked. I had to buy a whole 90 parts car just for the engine mounts for my GTV to V6 convetsion.

I do know of one Alfetta running a 24v V6 conversion. You'll need pretty deep pockets but it's the ultimate sleeper!
Now:
2012 Giulietta QV
1982 GTV6 3L fast road build
1966 Giulia Sprint GT Veloce...the long term project
1970 1750 GTV project car for sale

Then:
2002 156 2.5V6 Manual
2012 159 2.4JTDm Sportwagon
1973 2000 GTV with a 1750 rear half...that was a shame!
Alfa 90 (only for its engine mounts)

i agree with Beatle completely , and ill go one step further unless you put the 3.0ltr in a 1750 or a 2000 with the right setup
ie cams and carb jettings goes better than a 2,5 stock
115kw V6 versus 118kw 2000 with setup below is the stock 2000 versus 2.5 v6
with the right very easy setup the 0 to 100 for the 4cyl is around 7.7sec
