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.

History of the Sandman

The Holden Sandman, a car that represented a generation of Australians and likely one of Holden’s most iconic cars has undergone a number of reincarnations throughout its lifetime. While the true Sandman will always remain the 1970’s surf and lifestyle icon for most, the Sandman name has been used on a number of cars throughout the four decades between then and now. In this week’s blog we’ll recap the different looks the Sandman has undertaken throughout the years.

The Original Sandman (HQ, HJ, HX, HZ)

A combination of the ever increasing costs associated with owning a sports car combined with the increasing liberation and freedom of the youth of Australia led to a boom in the popularity in panel vans before the Sandman was even announced. Not one to miss a sales opportunity, Holden brought out the Sandman, a panel van by nature, with the added performance and luxury initially of the Belmont and eventually the Kingswood. Optional extras included the 253ci V8, a mattress, and sunroof while softer suspension and a drop-down split tail gate for ease of access differentiated the Sandman from the regular panel van. Understandably the Sandman was a huge hit among young Males who now had a car that could do everything – you could sleep in it, transport surfboards and ‘woo’ mates and lady friends alike; the Sandman was sexy.

The Concept

In 2000, Holden teamed up with surf wear brand Mambo to create a modern day Sandman concept. Based on the VU ute, the Sandman concept was received very well amongst the general public, with many calling to introduce it into production. Featuring a ‘burnin’ love’ interior, ‘bushfire orange’ exterior and the Sandman logo gracing the tailgate - the concept was true blue Aussie. Gracing the side panels were murals designed by Mambo’s head art director, featuring bush and beach goddess’. In reaction to the favourable reception from punters, the Sandman styled canopy was included as a $6,150 option to regular Utes in 2003, although was discontinued in 2006 when interest decreased, not to mention the incredibly complex nature of installation.

The Race Car

Supercar team Red Bull Holden Racing set about creating a tribute to the original Sandman in 2014 when they created their new ride car. In what looks like a VF ute from the side, and a VF Wagon from the rear, the Red Bull Sandman was met with mixed reception, although is none-the-less, an impressive vehicle. The car was originally built with a 700HP V8 and featured new-to-the-sport technology such as paddle shifting and a fly-by-wire throttle. This year, however, the Sandman has been used as a test dummy for the incoming twin-turbo V6 that will grace the sport come 2019. The car was used to unveil the new engine to the public in October 2017 with demonstration laps at the Bathurst 1000.

The 40 year anniversary ‘reincarnation’

In 2015, Holden decided it was time to reincarnate the Sandman in the form of a limited edition Sportwagon and Ute. Although without a true panel van option, purists were left disappointed in what were essentially SV6 or SS-V Commodores with added logos, pinstripes and a ‘retro’ coloured interior. Given the small production run of only 250 across all options, the 2015 Sandman may very well end up a collectable in the future, particularly as Holden manufacturing in Australia has ceased. Time will tell…

The Kia Stinger - a New Favourite?

The long awaited Kia Stinger has finally hit Australian roads over the past 6 weeks and we are getting our first look at how the Australian public is reacting to the Korean hatch/sedan which is being dubbed as a potential Commodore and Falcon replacement. While it’s by no means perfect, initial reviews of the range-topping Stinger GT have been overwhelmingly positive. The Stinger GT has to get a number of runs under its belt before it can truly be considered a car that will replace some of Australia’s most loved cars; but it has gotten off to a great start!

The Good

Straight off the bat, the appearance of the Stinger GT is great, and the latest and greatest in a line of Kia’s over the last 10 years that have progressively gotten better and better in terms of both appearance and performance. The sleek lines of the Stinger result in an exceptionally efficient aerodynamic package while large vents in the front and at all four corners serve to keep both the 3.3 litre twin-turbo’d engine and Brembo brakes cool.

Packing 272kw and 510nm the GT has plenty of go, and will at least match, if not better 0-100 times of both the Commodore SS and XR6 Turbo Falcon of years past. The interior is neat, polished and will rival that of any in the sub $60K price bracket, with a ‘squared-off’ steering wheel and a sporty driving position contributing to the overall premium feel of the car.

The 8 Speed Automatic Transmission is a truly impressive unit, taking like a duck to water to Australia’s driving conditions and contributing towards a ‘real-life’ fuel consumption of around 8L/100km on the open roads and around 11.5L/100km during normal city driving. The GT’s suspension has also received positive reviews, with a sports mode coping with all but the most spirited of driving while the comfort mode provides a compliant ride in more traditional driving scenarios.

Overall, there is a lot to like about Kia’s new Halo car.

The Not So Good

One of the major reasons both the Commodore and Falcon were so popular for so many years was the ability to comfortably seat 5 adults, and a family holiday with 3 kids and the Caravan in tow was a walk in the park. Unless your name was Aaron Sandilands you probably weren’t going to be complaining of a lack of head room either. This is one area that the Stinger falls flat, as a result of the slightly smaller dimensions all round, the Stinger will not comfortably carry 5 adults, nor will it provide ample headroom for those of us north of 6-feet tall.

Towing Capacity is at 1500kg while the down-ball rating is a meagre 75kgs, which means this will likely not be a suitable option for those with caravans, larger boats or anything particularly heavy that requires towing.

Perhaps the most griped about disappointment is the sound coming out of the Stinger GT’s standard exhaust. The GT, with the standard exhaust is quiet, too quiet for a performance car. Fortunately Kia realised the issue and has fast-tracked an optional bi-modal exhaust which should be available before year end for $2659.99. Videos of the new exhaust system show a much throatier sounding note, more akin to that of typical sports cars.

The Verdict

The Stinger GT is a very good car which is sure to prove itself a hit with the Australian public, is it a like-for-like replacement for the departing Aussie classics? Not quite. While it ticks the RWD and performance boxes, it doesn’t quite match the Commodore and Falcon in terms of usability or ‘street-cred’. The Stinger GT however will be considered one of the best value for money sports sedans in the world, taking the fight to many higher credential offerings from its European rivals.

2017 Motorsport Year in Review

2017 has been a year to remember in motorsports worldwide, with champions crowned, rising stars established and the rest going back to the drawing board hoping for a more successful 2018. At Rare Spares we’ve been glued to our TV sets throughout the year keeping track of all the major forms of racing around the globe. From TCM to Formula 1, in this article we’ll take a quick look at the categories that caught our eyes in 2017.

Touring Car Masters

Touring Car Masters produced another classic racing season as Steve Johnson stormed his way through the second half of the season to take out the Pro class. John Bowe and Adam Bressington rounded out the podium, while a huge crash at Winton captured headlines when a no less than 12 cars were caught up in a pile up at the second corner. The TCM category is going from strength to strength attracting a number of ex pro’s providing the ultimate challenge to the amateur participants.

Supercars Australia Championship

What a season for Supercars, Jamie Whincup took the title for the seventh time, with the fight between himself and Scott McLaughlin coming down to the very last lap of the season. The eventual margin of victory was 21 points after McLaughlin was penalised 25 seconds for squeezing a hard charging Craig Lowndes into the wall on the last lap of the season. David Reynolds and Luke Youlden were popular Bathurst 1000 winners while Chaz Mostert and Steve Owen took out the Enduro Cup. The category’s first female driver Simona Di Silvestro finished in 24th place, but produced a few moments that suggest 2018 could be an exciting year for the Swiss native.

Bathurst 12 Hour

Taking place way back in February, the Bathurst 12 hour was won by Marinello Racing with Craig Lowndes, Jamie Whincup and Toni Vilander behind the wheel. Shane Van Gisbergen and his Scott Taylor Motorsports teammates put up an incredible fight before SVG put the incredible AMG into the wall while trying to chase down his Red Bull Racing teammate Jamie Whincup. The 2018 edition is fast approaching, and catching our eyes is the inclusion of a classic car event at this year’s 12 hour. Group S cars will be taking to the grid, with everything from Austin Healy’s, MG’s and Porsche’s taking part in a support race.

Formula 1

British superstar Lewis Hamilton claimed his fourth World Championship and Mercedes claimed their fourth constructer’s championship in a row. Ferrari regained some level of form in 2017 as Sebastian Vettel held the points lead for much of the first half of the season. Australia’s Daniel Ricciardo was left frustrated due to the lack of pace and reliability in Red Bull’s 2017 power units, meaning only one win was recorded for the popular West Australian.

NASCAR & IndyCar

Martin Truex Jnr took out the premier class of NASCAR in 2017, winning the final event in Miami to round out the ‘playoff’ series with a lead of 5 points over Kyle Busch. IndyCar headlines were dominated by Fernando Alonso in 2017 as he began his quest to conquer motorsports ‘Triple Crown’ (Monaco GP, Indy 500 & Le Mans). Alonso impressed in his first IndyCar outing at the Indy 500 and even led the prestigious race at one point before an all too familiar Honda engine failure left the Spaniard stranded. Takuma Sato won the event while Josef Newgarden went on to take out the title.

Five Memorable Summernats Grand Champions

Summer is fast approaching and for many that means one thing; Summernats. Summernats plays host each year to Australia’s best show cars, street cars, burnout cars and more in a festival of cars, music and burnt rubber. Each year the elite entrants compete in a series of events to establish who is the year’s Grand Champion, with criteria stretched from the typical ‘car show’ presentation points to include a number of driving tests. A scroll through the list of previous Grand Champions is like a walk through one of the most impressive car museums you’ve ever seen, and in this article we’ll take a quick look back at some of our favourites.

Rob Beauchamp’s VL Commodore – Top Street Machine Overall at Summernats 1, 2 & 3

Rob’s Jaw dropping VL Commodore will be remembered as not only one of the meanest VL’s in the land, but as also a car that pushed the limits of the term ‘street machine’. Fitted with a Kinsler-injected 302 Chev at the time, the VL was a full blown drag car, capable of mid 10’s and barely suited to use on the street. It was the immaculate attention to details that won fans and judges alike to win the then named Top Street Machine overall at Summernats 1, 2 & 3.

Howard Astill’s Rock Solid 3 – Grand Champion at Summernats 4 & 5

Howard Astill’s XA Falcon went through a number of guises throughout the late 80’s and early 90’s before it was reborn as the gobsmacking Rock Solid 3. Featuring an ever-so-cool neon paintjob, Rock Solid 3 typified what the punters love about show cars – it was fast, loud and eye catching. The XA would dominate Summernats 4 & 5 before being parked to allow Astill to move on to the next of his many incredible builds. In recognition of his contribution to the show car scene, Astill was honoured as a Rare Spares Legend in 2009 – check out our blog from 2015 with Howard here.

Joe Lore’s BLOWJO XY Falcon – Grand Champion at Summernats 23

Everybody loves an XY, and you’ll struggle to find any better in the land than Joe Lore’s purple beast. Featuring a 351 Cleveland (stroked to 383cu) and a humungous blower, BLOWJO is an incredibly striking vehicle that ran away with victory at Summernats 23 in 2010. If you haven’t had the chance to see this XY up close yet, keep an eye out for the incredibly detailed airbrush work on the interior and underbody, this car is a true work of art.

Peter Fitzpatrick’s ’59 FC Holden – Grand Champion at Summernats 2

A six time Grand Champion winner, Peter Fitzpatrick is a name that stands without peer in the Summernats history books. At Summernats 24 Peter Fitzpatrick arrived with his ’59 FC Holden and swept all before him, taking out not only the coveted Grand Champion award, but also winning the People’s Champ and Top Judged awards, the first to do so in the history of Summernats. Peter Fitzpatrick is also a Rare Spares Legend, recognised in 2012 for his legendary contribution to the street machine community.

Mark ‘Happy’ Williams’ HQ One Tonner – Grand Champion at Summernats 30

The most recent Summernats Grand Champion winner, fan favourite Mark ‘Happy’ Williams and his HQ One Tonner was a popular winner with the huge Summernats 30 crowd. The Supercharged One tonner is a sight to behold and sounds incredible, becoming the first Western Australian built car to take out the Grand Champion sword at the 2017 event. An emotional victory for Williams, who lost his father only days before the event, in his memory the car’s license plates were changed from ‘2HAPPY’ to ‘4MYDAD’.
