History of the LS Engine

There’s a saying in the automotive world: “There’s no replacement for displacement.” Somehow, that tag became attached to an engine, in a vee shape and packing eight cylinders, made by Chevrolet in America.

In the late nineties General Motors and Chevrolet debuted a new V8. Dubbed “LS” for “Luxury Sport” it’s this name and engine that have popularized the above saying. First seen in the 1997 C5 Corvette, the all “aluminum” block, called the LS1, was also known as the small block Gen111. It replaced the LT or “Luxury Touring” engine that had been a mainstay for some time.

It was what’s called a clean sheet design; essentially a start from nothing design, the only common points the LS had with the LT was bore spacing and conrod bearings. Even in the LS range of engines themselves items such as the bore centre, at 4.40 inches, cross bolted six bolt main bearing caps, and a four bolt per cylinder head bolt pattern are common.

Alloy blocks are used for performance oriented vehicles whilst blocks made of iron are used for SUVs and trucks.

At 5.7 litres or 350 cubic inches in capacity, as the most common iteration is seen in, it produced 257 kilowatts or 345 horsepower. Maximum torque was 470Nm or 350 pound-feet, found at 4400rpm. It was bolted into a substantial range of cars such as the Corvette, Firebird, and of course in Holden and HSV cars like the Statesman and Senator Signature.

LS6 is the name given to a higher output but same capacity engine largely found in the C5 Corvette Z06, with production starting in 2001. Peak grunt was bumped to 287 kilowatts and torque to 522Nm initially, with further development lifting both to 302kW and 540Nm.

There were also smaller engines based on the same architecture. Engineered for use in passenger SUV and trucks, the LS1 4.8L and 5.3L blocks have a 3.78 inch diameter for the bore.

In 2005 GM unveiled the GenIV or LS2 engine. There were bigger capacities, cylinder deactivation technology for improved fuel savings, and variable valve timing. Capacity went to 6.0L (5964 cc in real terms) or 364 cubic inches. Base engines made 300kW and 542 Nm. Holden and HSV saw this installed in cars such as the Monaro and Grange.

L76 is the designation given to the LS2s fitted with Active Fuel Management or AFM. It was some time before Holden chose to use the feature; from 2009 it was installed however only in cars with an automatic called the 6L80. Power was rated as 260kW and maximum twist of 510 Nm came in at 4400rpm. Designed to assist in bettering fuel economy by shutting down firing in four cylinders, the engine gave rise to the L77. This designation defines the LS2 as being ethanol fuel compatible.

Various engines with names such as LY5, LH6, and LMF were produced and seen in SUVs such as the Chevrolet Trailblazer and GMC Savana.

LS7 was a rarely seen engine in Australia. It was intended to be produced for a specific HSV car here called the W427. Corsa Special Vehicles beat HSV to the punch here, with their engine producing 400kW and 600Nm. HSV’s version, first shown at the 2008 Melbourne International Motor Show, offered 375kW and 640Nm.

A supercharged and slightly capacity increased engine, at 6.2L and called LSA, was released in 2009. This was first seen in the ballsy Cadillac CTS-V and Australia had it in the GTS, GTS-R, and Maloo R8 LSA, just to name a couple. 480kW was the peak power and an amazing 754Nm of torque. These came courtesy of a block with revised compression, cast pistons, and a “blower’ of 1.9L in capacity.

With Holden ceasing local manufacturing in late 2017, the LS engines are now only to be found in cars already on Australian roads or in vehicles allowed to be imported from the US to Australia.

For now….anyway. Stand by for Camaro.

Sinful Conversions - Engine Conversions That Cause a Stir

In the automotive community, we’re no strangers to engine conversions. Whether it be a neat LS-swap or dyno warping Barra-swaps, we tip our hat to clean and well-engineered engine transplants. However, not all engine conversions make the automotive gods happy, some are downright riot-inducing, with enthusiasts from all corners kicking up a stink. In this article we will take a look at a handful of controversial engine conversions.

Ford Barra Powered HG Belmont

Searching for something a little different from the tonne of LS-swaps around these days, this owner decided to take the ever-popular Barra engine and slot it into the early 70’s Holden. With a sub-11 second quarter mile time the old “Holden” will towel up many popular sports cars, whilst still being used by its owner as a daily driver!

 

Skyline GTR Powered Torana

Dropping powerful engines in smaller cars has been a passion of many a person since the dawn of time. As automotive enthusiasts, we can’t help but look at a car, bike or boat and wonder what we can do to make this faster? Well, in the case of the LX Torana, dropping a twin turbocharged RB26 under the hood is sure to make the trip from A to B in quite a hurry! There are of course a few Holden enthusiasts who are none too happy with a Japanese heart beating in the Aussie legend.

 

LS1 Powered XY Falcon – XYYNOT

This XY Falcon will surely cause a stir amongst both Holden and Ford fans, with one of the most iconic Falcon’s receiving a Chevrolet heart. Featuring a Harrop blower, the cammed, near stock LS1 is producing a solid 458 rear wheel horsepower and is used throughout the Australian drifting circuit!

 

1967 Pontiac Firebird with Toyota Prius Hybrid System

Coming completely out of left field is this Prius-powered 1967 Pontiac Firebird. Enough to make any rev-head cringe just a little bit, this engineering marvel has set the owner back just over $10,000US to date and is expected to be on the road by 2019.

 

LS1 powered Porsche 911 

Porsche fans – turn away now! Replacing the iconic flat six in the rear of this 1986 911 is the tried and true LS1, resulting in a horsepower gain of over 170hp! From a purely performance point of view, when you take into consideration other upgrades including wheels, tyres and suspension, this Porsche is a bit of a weapon. However, the purists still cringe at the thought of anything other than the flat six gracing its engine bay.

Have you heard of any crazy engine swaps that make purists cringe? Or maybe you’re in the process of your own engine swap? Head over to the Rare Spares Facebook page and let us know in the comments section below.
