ALFA FLAT-4 IN 914

Does anyone know if someone has put an Alfa Romeo flat four engine in a 914?

Why would you want to? Only thing on earth (besides British cars) that requires more maintenance than a Porsche is a Fiat.
Flame on.

...And this, from someone who turbocharged a 2.0 914 motor (with a side-draft carb, yet!) and is now playing with a Chevy V-8 in a 914.

Heh heh heh heh. Are the Powers of Orthodoxy starting to win you over, Sammy?

Yea, I guess I shouldn't talk.
I drove a buddy's Fiat in high school for a while, biggest POS i ever climbed into. I shouldn't judge all of them by that hacked up piece, but I have never got it out of my system.

How about a Tatra Aircooled OHC V-8 3.5 liter?

Oh, Fiats aren't that bad. Some models have rust problems, but not all. We had a 131 that was a lot of fun... well... until the exhaust pipe broke in three pieces, and when the oil pickup tube shattered. hmmm...

To get back to the original post, this guy wanted to put an Alfa flat-four in, which is an honest-to-God Alfa engine, not a badge-engineered modern FIAT engine. I don't know that FIAT ever made a flat-four. But the Alfa Sud flat four is reputed to be a great engine, though the car bodies rusted away around the engine. They had a single overhead cam one each side, all I think had dual carbs and some had FI. They're water-cooled, which would be a challenge, and I wouldn't personally want to try the swap. Suds were never sold in the US, though there are two or three around. The engines are small displacement compared to any 914; the first were 1100, I think, and grew eventually to 1600. The same basic engine was used in the later 33 models. Tons of them in English and Italian junkyards, I'd think.

A water cooled Alfa Sud boxer has genuine cred in a 914, because it was a Porsche design project for AR. Methinks the transaxle with in-board disc brakes was also a Porsche project, because the Sud was Alfa's first front driver.

Car was built in a new plant in Southern Italy (hence Alfa Sud) to alleviate chronic unemployment.

Fantastic to drive (though a bit underpowed), it was full of Alfa advances like properly sorted front strut suspension, responsive steering and in-board front brakes. Flat four engine alllowed a super-rigid body design. You yanks would have loved them.

Downside was crappy build quality which allowed tin worms to take quick hold in early models. Later cars were much better.

Engine is a gem. Loved to rev, super-rigid one-piede iron case, cross-bolted mains. Con rod caps are a work of art!

In Oz, later Suds and the Alfa 33 evolution went to 1750 cc capacity with DOHC and EFI. Engine was still around in the late 80s in an Alfa Romeo / Nissan joint venture.

Quite a few Alfa-powered V-Dubs and specials in Oz, although the Subaru flat four is now the go, due to better availability and bigger capacity.

For something completely different, Citroen built a car called a GS (like a stumpy CX), with an air-cooled flat four. With SOHC and roller bearing crank, this was a bloody ripper even from 1200 cc and just wanted to go and go.

Anyone have a picture of this Alfa motor? I like the idea of a one-piece case. I think a cool new flat-four would be one with a one-piece case that also incorporated the "Lanchester design" to eliminate the rocking couple produced in a normal flat-four.
