Alfa Romeo V6 engine#3.0

A {{cvt|1996|cc|L CID|1|order=flip}} version was introduced in 1983. Both carburetted {{cvt|136|PS|kW hp|0|lk=on}} and fuel-injected {{cvt|132|PS|kW hp|0}} versions were available from the start.ELABORARE: [https://www.elaborare.com/83943-motore-alfa-romeo-v6-tuning-auto-storiche/ Motore Alfa Romeo V6 — ELABORARE], accessdate: 14.

• 1984–1987 Alfa Romeo 90

A {{cvt|1996|cc|L CID|1|order=flip}} turbocharged version, derived from the 3.0 L 12v, first with total digital management, was introduced in 1991 in the Alfa Romeo 164 with {{cvt|210|PS|kW hp|0}}.Boitier Rouge: [http://boitierrouge.com/2014/05/25/alfa-romeo-164-la-meilleure-des-tipo-4/ Alfa Romeo 164 : la meilleure des « Tipo 4 » ? | Boitier Rouge], accessdate: 14. September 2018 The engine has a bore and stroke of {{cvt|80x66.2|mm|in|2}}. It was mainly intended for domestic market, due to Italian law at the time taxing cars with engines with larger displacement than two liters at a higher rate.

Applications:

• 1991–1992 Alfa Romeo 164
• 1992–1997 Alfa Romeo 164 Super
• 1994–2000 Alfa Romeo GTV
• 1998–2000 Alfa Romeo Spider
• 1996–2000 Alfa Romeo 166 Super

The original engine displaced {{cvt|2492|cc|L CID|1|order=flip}} and produced {{cvt|158|PS|kW hp|0}}. It was a 2-valve-per-cylinder design with a single belt-driven camshaft per cylinder bank and six carburettors. The engine has a bore and stroke of {{cvt|88x68.3|mm|in}}.

The Bosch L-Jetronic fuel injection was added for the 1983 Alfa 6, which produced the same {{cvt|158|PS|kW hp|0}}. The 2-valve engine ended its life in the Alfa 155, where there were two series for this engine, the {{cvt|2492|cc|L CID|1|order=flip}} developing {{cvt|166|PS|kW hp|0}}.{{citation needed|date=October 2018}} Differences between them were small and only on torque and power delivery producing exactly the same horsepower.

In 1982, the German Alfa Romeo dealer and tuner Gleich offered a 2.8 conversion of the GTV6 2.5 engine. Dieter Gleich was sure that engine displacement enlargement is still the best and, for the life of the engine, the healthiest way of tuning. The engine capacity was increased to nearly 2.8 liters by using new bushings and custom-built forged Mahle pistons while the compression ratio was raised from 9.5 to 10.5:1. The 2.5 liter was rebored to {{cvt|93|mm|in|2}}. Total displacement was {{cvt|2783.7|cc|L|1}}. Power produced were {{cvt|191|PS|kW hp|0}} at 6,300 rpm and torque {{cvt|24.6|kgm|0}} at 4200 rpm.Classic Cars: [https://www.classiccarsmagazine.nl/model/alfa-romeo-gtv6-2-8/ Alfa Romeo GTV6 2.8 specificaties en info — Classic Cars], accessdate: 14. September 2018

The magazine "Sport driver" tested a 2.8 Gleich powered GTV6 in June 1982:

"After engaging the first gear and a somewhat careless step on the gas pedal you get a touched feel to the epiphany GTV6 shot, accompanied by the typical Alfa Romeo exhaust sound. It was a pleasure. The fact was the sprint from 0 to {{cvt|100|km/h|mi/h|0}} is not further under the seven-second limited by a tricky-to-be-shifted five-speed gearbox. The really vehement propulsion waned only when the speedometer {{cvt|230|km/h|mi/h|0}} mark has left behind. Another eye-opening experience awaits when you realize that the lightning speed to 7000 rpm rotating in any gear pinion even in fifth gear still from 1500 rpm is completely smooth."

Applications:

• 1982 Alfa Romeo Alfetta GTV6 2.8 Gleich

The original 2.5 engine as used in the Alfa 6 was bored and stroked by Autodelta, the former Alfa Romeo racing department to match the racing rules for South African and Australian championships. Bore was increased from {{cvt|88|mm|in|2}} to {{cvt|93|mm|in|2}} and a new crankshaft stroked to {{cvt|72|mm|in|2}}. The total displacement was {{cvt|2934.5|cc|L|1}} and it's a totally different engine from the later {{cvt|2959|cc|L|1}} that powered the 75/Milano models. It was, too, a 2-valve-per-cylinder design with a single belt-driven camshaft per cylinder bank and six carburettors. Special camshafts and carbs were used giving a power figure of {{cvt|176.4|PS|kW hp|0}}{{citation needed|date=October 2018}} at 5800 rpm. Torque was {{cvt|222|Nm|lb·ft|0}}{{citation needed|date=October 2018}} at 4300 rpm, while compression ratio was 9:1.

Only 174 complete GTV6 3.0 SA cars were produced in 1984, plus 68 more in 1985. The last ones built were fitted with electronic fuel injection.

The 3.0 GTV6 was sold in South Africa in 1983–1985, predating the release of the 3.0 L displacement to the rest of the world.CAR magazine: [http://www.carmag.co.za/buying-used-cars/classic-buy-alfa-romeo-gtv6-1982-1985/ CLASSIC BUY: Alfa Romeo GTV6 (1982–1985) — CAR magazine], accessdate: 14.

Applications:

• 1984–1985 Alfa Romeo Alfetta GTV6 3.0 SA

Pulled by the racing success of the 3.0 SA engine and looking for more power to boost 75/Milano sales in countries like USA, Alfa Romeo introduced a production version of the 3.0 engine. Bore was {{cvt|93|mm|in|2}}, as the 3.0 SA, but stroke was increased to {{cvt|72.6|mm|in|2}}. The total displacement was {{cvt|2959|cc|L|1}}. As the previous engines, it was a 2-valve-per-cylinder design with a single belt-driven camshaft per cylinder bank. The main difference with the racing 3.0 SA was the use of modern L-Jetronic fuel injection system by Bosch. Power figures vary from {{cvt|188|PS|kW hp|0}} to {{cvt|192|PS|kW hp|0}} at 5800 rpm,{{citation needed|date=October 2018}} with compression ratio 9:1.

This engine was modified for transverse placement in the 164 and fitted with a high-performance camshaft and low-restriction exhaust, producing {{cvt|192|PS|kW hp|0}} in standard form, {{cvt|184|PS|kW hp|0}} when a catalyzer was added in 1991, with the Cloverleaf version producing {{cvt|200|PS|kW hp|0}}.{{citation needed|date=October 2018}}

The same engine was fitted to the SZ and RZ — ES30 Zagato, but even more finely tuned with wilder cams and high compression pistons to a further {{cvt|210|PS|kW hp|0}}.Fast Classics: [http://www.fast-classics.com/cars/alfa-romeo-s-z-2-for-sale/ Alfa Romeo S.Z. | Fast Classics], accessdate: 26.

The engine was upgraded to dual overhead cams and four valves per cylinder in 1993. Due to this and other refinements, this engine produced {{cvt|211|PS|kW hp|0}} for the regular 1993 Alfa Romeo 164, with {{cvt|230|PS|kW hp|0}} and {{cvt|276|Nm|0}} in the 164 QV with its engine producing {{cvt|232|PS|kW hp|0}} on the Q4 model which in its final production run in 1996, it got reduced to {{cvt|228|PS|kW hp|0}} but with increased torque.Quattroruote.it: [https://www.quattroruote.it/tutte-le-auto/alfa-romeo/164 Listino ALFA ROMEO 164 (1987–1998) — prezzi, caratteristiche tecniche e accessori — Quattroruote.it], accessdate: 14.

In December 2002, at the Bologna Motor Show, Alfa Romeo displayed a 156 GTAm prototype, built by N-Technology, with 3458cc. The power was increased to 300 PS at 6,800rpm. The engine had a bore and stroke of 97 mm x 78 mm. This version never came to production, and it was based on N-Technology's experience racing the 156 GTA SuperTuring.

Alfa Romeo raced, in early 1990s, a 2.5-litre engine based on Busso's 60º V6. The engine was substantially revised and had a difference bore and stroke from the 2.5 standard engine, respectively, 93 mm x 61.3 mm, and making 420 bhp (313 kW) at 11,800 rpm with a torque of 294 Nm. Alfa Romeo, during the 1993–1996 era of DTM/ITC, racked up an incredible thirty-eight victories of a total of eighty-nine starts. The V6-engined machine also qualified on pole nineteen times and set the fastest lap in forty-two races.

Later, Alfa Romeo also raced a development of the Peugeot, Renault, Volvo 90° V6 engine, with 490 PS at 11,900 rpm, in the 1996 DTM Championship.YouTube: [https://www.youtube.com/watch?v=DRcFpmQL3bc Limone Racconta: La verità sul motore Alfa 155 V6 Ti + 156 e Fulvia Concept — Davide Cironi (SUBS) — YouTube], accessdate: 26 July 2018

Alfa Romeo worked on other displacements, specifically a 2.8L (2846cc), with 88 mm bore (same as the 2.5 liter engine) and a 78 mm stroke (same as the 3.2 liter engine). According to Alfa Romeo engineers, there were considerable gains, especially in torque. However, this engine never made it into series production.

Some private workshops work on these engines to obtain larger displacements (and power outputs), with diameters of 101 mm (3.75L) or even 103 mm (3.9L).
