Used Alfa Romeo Engine Models

Used Alfa Romeo Engine

The flagship of Alfa Romeo is its twin-cam engine. They have defined the brand from 1954 to 1995, starting from the First Giulietta to the Last Spider. There was a tremendous team of engineers headed by Orazia Satta Puliga, who worked on this project. The Giulia Ti engine in 1962 was one of the latest designs of its time. The twin plug head increased the horsepower by a substantial 5% than before. The subsequent power increase made a name for the engines in racing tracks. The twin-cam engines always proved all the more efficient in tracks with GTA 1300 Junion being its classical example.

Being civil, looking sporty, and packed with power, all at the same time is what Accura engines promise you every time. The first Busso V6 2.5 SOHC 12V was featured in the 1979 Alfa Romeo 6. Its selling point was the Dellorto FRPA 40 carborators. The V6 soon found its place under the hood of Alfa Romeo GTV 6, a journalist and car enthusiast’s darling in its time. Car enthusiasts and collectors rave about this car, even to this date. The Busso V6 is often dubbed as the Arese’s violin, factoring in the sweet sound of the engine. Trust us, when it’s on, the road or tract, the engine is just music to the ears.

Every Alfa Romeo in the early 80s got the fuel-injected Busso. In 1986 Fiat undertook operations of Alfa Romeo. Since then, Alfa Romeo shifted away from rear-wheel drive to front-wheel driving. The front wheel drive 164 released in 1987 became the Alfa’s new flagship. Busso V6 graced its presence under the hood of this car as well. Even an acquisition from Fiat cannot do away with the Busso. However, the Busso outgrew itself from 2.5 Litres to 3 Litres. It also received some cosmetic makeover to make the Busso engines all the more cooler. The shiny reflective tone remains a stunning visual feature under the hood till the end of production. It wasn’t until the late eighties, that the two-valve cylinder remained relevant and in fashion.

SZ engines

It was in 1989, that the SZ took away the market by storm. From 12 V in 1989 to V6 Turbo in 1991, the swansong continued. The turbo was available in 166 and GTV coupe. By 1992, the engineers moved to two more cams and 12 more valves to transform the industry. The competition from other European carmakers pushed the market to insane limits. The marvels of engineering made life more exciting for every car owner behind the wheel. The technological advancements had no bounds and knew no limits. Every new engine boasted impressive numbers and proven performance records.

In 2001, 156 GTA was launched before shutting down operations of the racing plant of Alfa Romeo. Busso engineers were the only thing continuing with Alfa Romeo which is what defined their cars. Busso found its presence under the hood of 2002 147 GTA as well. The engine accelerated the car to over 100 mph within 6 seconds. It was an impressive turnaround more than two decades ago. Even today, it is still an appealing figure in the industry. Busso engines proved impossibly smooth and offered unbelievable acceleration to the GTA. To everyone’s dismay, Busso V6 production officially ended by the end of 2005. Almost immediately, the man behind his brainchild, Guiseppe Busso died on 3rd January 2006.

Engine specs

The Busso was available with engine displacements in the range of 2 to 3.2. The bore range was 80 to 93 mm and the stroke was in the 66 to 78 mm range. Irrespective of displacement, the engines featured an open deck and aluminum block. Though it’s open open-neck design, it is still a very rigid construction. Inside the engines, you have the efficiently designed crankshaft. Larger flying arms separating the crank pins made up the forged, fully counterweighted crankshaft. It included connecting rods, which are also forged and cast pistons. Unlike other V6, the Busso features no balancing shafts, being balanced externally by offset weight crank pully and flywheel.

Another talking point about Busso engines is their conservative compression ratios. 2.0L Turbo had a compression ratio of 8:0:1, while 2.5L 12 V upped it to 9:0:1. 3.0L 12V SZ pushed compression ratio to 10:0:1. while the 3.2L 24V GTA has the optimal 10:5;1. Busso has two versions of the cylinder heads – 12V and 24V. The former has one camshaft per head, directly actuates intake valves, and indirectly actuates exhaust valves through the push rods. The 24V contains two shafts in each of the heads. They directly actuate all the valves with the assistance of hydraulic lifts.

The valve sizes in 12V engines are 36.5 in exhaust and 41 in intake. Similarly, the intake valve size is 35.6 in intake and 32 in exhaust. TIll the Busso existed in 2005, they had no variable valve timing or valve lift. Though they have stopped production, Busso engines are still popular, whose drawbacks can be sorted out with a few tweaks. It is still a car collector’s and enthusiasts’ darling for the amount of Italian fury it packs for the American roads.
