Meliora, ADM, Sanda & Mastiff engines (U4)


Reviving this thread, but this time with only U4 engines from my companies. I tend to use an engine family a lot and for several years, so updates are scarce, but you can find maybe some engine to fit in your cars and lore.


ADM Venturi series I

The venturi series are carburetor engines. The L6 is based in some dodge engines from the 40s and the L4 follows the same philosophy, a wide powerband and early peak torque. These engines should be in the realistic side of the engines from that time. They’re also quite economical.

Classic Mastiff V8

A evolution of the Venturi 400. It was used in a variety of applications, due to its compact, durability and simple design, ranging from low octane with a wide powerband to highly modified steep powerband.

That’s an impressive collection of classic engines, spanning the whole spectrum from economical straight-fours and sixes to full-on race-tuned bent-eights!

Second Meliora’s engine. It was an evolution over the previous 19L6. It was fairly small in displacement, but it had a new valve system, leaving the old OHV layout behind.

Meliora applications:

###21LDC (1968)

2.2L - 84 x 66
Bored up version of the DAOHC6. Slightly more powerful.

Meliora applications:



The Alu4 was the natural evolution of the Modular 4. It began as a sort of “test-on-the-job” engine, and it used some of the new technologies ADM will use later on in all their engines, such as direct-acting overhead cams. Initially it was planned to be built entirely of aluminum, but that was too expensive, so the engine was built with aluminum block and iron heads instead (although this idea was abandoned for a few years).

###20L1Ca2Ba (1969)
2L - 83.2 x 92


###22L1Ca2Ba (1969)
2.2L - 88 x 92




Known only by the name of ADM V6, this engine was the evolution of the previous Mastiff L6, this time with a reworked engineering, like the direct acting over-head valve system from the Alu4, and a new packaging, making it quite small despite its full displacement (up to 4L claim some sources). Originally design to be fitted in a longitudinal FWD system, with a few modifications it was also used in longitudinal RWD.

Since the mid 70s and the mandatory used of catalytic converters, this engine replaced the L4 as the smallest engine offered in most models (cat sucked too much power out of the Alu4)

ADM - 1990 Tulum


By 1974, after the dead of Eugenio and the re-estructure of the Meliora, they were ready to present their first 4 cylinder engine. Named 4C1BL, the engine was intended to be used in family cars, however, due to upcoming emission regulations, the engines were fitted with catalytic converters, causing a significant drop in power. To address this issue, the engines were tuned for extra power, causing the fuel economy and the emissions to be incredible awful (even the ADM V6 got better economy despite being bigger).

#Barracuda V8

Following the family of the new direct acting ohc engines ADM had designed, the Barracuda was reserved for the more heavy or sporty cars in their line-up.

ADM engineers were trying to emulate the magic of the Classic Mastiff V8, that was used in a lot of different applications. However, the economic and oil situation didn’t make it possible. The engine was only used (up to 1975) in the Rivera and the Foxhound, and when the regulations required catalytic converters, the engines were reduced to a shadow of what they were captable of doing.

Even with a catalytic converter in place the Barracuda V8s would have offered plenty of bang for the buck. 250 horsepower from the 6.0 would have been enough to embarrass most contemporary American pony cars, and even give some expensive European sports cars a real fright in a straight line!


The challenge will come later on, when these engines would need to meet the CAFE and environmental regulations, while remain very cheap.



The 6C28L was the evolution of the DAOHC6, tho it wasn’t really that better, it featured mechanical fuel injection and individual throttle bodies, making it quite responsive despite being significanly underpowered (due to the mandatory catalytic converter).

By 1975, Meliora developed an special version that unleashed the hiden potential of the engine, powering the '75 Perenne turbo and its racing counterpart. The turbo’d engine made 237hp at 5,700rpm. The engine was known for its weird behaviour, it had noticeable lag up to 2000rpm, then the engine kicked as the turbo spooled up to 3,000rpm, then it kicked again from 4,000 to 5,000rpm, making it quite difficult to handle on 1st gear or under low speeds.

Sanda B series 4 Cylinder engine

Sanda’s B series family of engines shared a similar architecture, all aluminum construction, direct acting overhead valve system and specially designed to be run as NA engines. The 4 cylinder engine family was designed and mainly used by Sanda, but some ADM models also used it. Although the japanese and american versions were compatible, european versions came without catalytic converters and were not allowed to be used in american models.
