Amongst the most craved performance cars in Australia at present are the S13,
S14 and S15 Nissan rear-drive coupes. These relatively lightweight cars are
renowned for their power, tough mechanicals, rear-drive handling and immense
aftermarket potential.
In this two-part series we’ll look back over the lineage of the popular
Silvia range and reveal some of the limited edition models you probably don't
know about...
1965 CSP311 Silvia
The world’s first glimpse of the Silvia came at the 1964 Tokyo motor show.
The original CSP311 Silvia was based on the existing Fairlady 1500 soft-top
platform (whose basic design stems back to classic British sports cars). The
attractive body of the Silvia can be largely credited to Dr. Albrecht Graf von
Goertz – a German designer with previous experience at Porsche, BMW and
Studebaker. Dr. von Goertz sculpted the Silvia to incorporate similar concepts
seen in the BMW 507 – a long bonnet line, thin pillars and bumpers, and
relatively large (14 inch) wheels. Dr. von Goertz was the first
designer working in Japan to employ a full-scale clay model.
And the CSP311 Silvia can be credited with some other ‘firsts’...
This was the first Japanese manufactured car to employ disc front brakes,
which combined with the rear drums used in the Fairlady. The wishbone front suspension and
leaf spring live axle rear suspension were a direct carry-over from the Fairlady,
except with softer settings.
Under its stylish long bonnet, the CSP311 Silvia packed a new 1600cc ‘R’
engine. The R engine used a 3 bearing crankshaft, pushrods, 9.0:1 compression
ratio, a lightweight pressed steel exhaust manifold, dual exhaust and twin 38mm
Hitachi carburettors. Output was listed at a creditable 66kW at 6000 rpm. Note
that a short time into the CSP311 Silvia’s build, the engine was revised with an
alloy cylinder head and 5 bearing crankshaft (which hints that there were
failures of the original 3 bearing unit). This 5 bearing 1600 was simultaneously
employed in the Fairlady 1600.
A 4-speed manual gearbox (boasting synchros on all forward gears) was
installed into the CSP311 together with a shorter diff ratio than found in the
Fairlady. This is said to improve acceleration to match the slightly lighter
Fairlady. Both the CSP311 Silvia and Fairlady weigh less than 1000kg.
Amazingly, the 1965 Silvia used hand-beaten body panels and each vehicle was
hand assembled. It is said that a very high quality exterior finish was achieved
but quality is poor beneath the skin.
Nissan Motor Company’s decision to hand assemble the CSP311 Silvia leads us
to believe the Silvia was never intended for high-volume production. And it’s
just as well. The American market (which Nissan saw as a major target) regarded
the CSP311 as too cramped and having a too small engine. Certainly, headroom was
limited and engine capacity was modest compared to other vehicles available in
America at the time.
The CSP311 was never officially sold in America but a small number were
exported to Australia (where it was badged as the Nissan 1600 Coupe). The car
was quite well greeted but with a price tag more expensive than a Lotus Elan, it
was never going to be a hot-seller. Over 90 percent of CSP311 Silvias were sold
in the Japanese home market – where they were even put to use as highway patrol
cars...
Only about 550 examples of these personal coupes were built.
1975 S10 Silvia
Curiously, some 7 years after the demise of the CSP311, Nissan decided to
dust off the Silvia nameplate.
In response to criticism of the original Silvia, Nissan made the next
generation (the S10) considerably more spacious and bulkier in proportion.
Nissan was rewarded with an export program to America - albeit in relatively
small numbers. In America, the S10 was fitted with larger bumpers (to meet more
stringent safety standards) and re-badged as a 200SX. But whatever it was
badged, the fact remains that the S10 was a humble Datsun Sunny beneath a coupe
body...
In its home market in Japan, the Nissan S10 came powered by a 1.8 litre
L-series 4 cylinder which, in fuel injected form, generated 79kW at 6000 rpm.
The US-spec version employed a larger 2.0 litre L20B engine producing about 70kW
but with meatier bottom-end torque.
Part of the reason for the S10’s relative success can be attributed to
Toyota’s popular Celica, which was paving the way to this particular niche.
However, compared to the original Celica, the S10 Silvia is a bit of an ugly
duckling... The appearance was tweaked in 1977 but this was merely a band-aid
solution to a major styling issue.
More than 145,000 examples of the S10 Silvia were built – a big improvement
over the original 1965 Silvia. Things were slowly starting to shape up...
1979 S110 Silvia
The ugly appearance of the S10 Silvia was forgotten with the 1979
introduction of the S110 Silvia. The S110 possessed the boxy styling that was to become fashionable during the ‘80s.
Note that, in many markets, the S110 Silvia was badged as Gazelle while the
US-spec versions continued with the 200SX name. Initially, the S110 was sold
only as a notchback coupe (seen here) but a hatchback version was released not
long into production.
A range of engines were available.
Most S110s were fitted with basic L-series carby engines, while a new fuel
injected 1.8 litre Z18 engine was available in up-spec versions in Japan. The
high performer of the range was the turbocharged Z18ET engine which put out
100kW at 6000 rpm. We believe these versions were badged as 180SXs in Japan.
In 1982, the S110 Silvia was updated and made available with an all-new 2.0
litre FJ-series 4-cylinder – the FJ20DE. The FJ20 brought a motorsport-inspired
DOHC, 16-valve head and fuel injection. The FJ20DE was fitted to only 2000RS
versions in coupe and hatchback body styles. These are a relatively rare and
desirable vehicle.
Meanwhile, the hottest Nissan S110 available to American buyers was powered
by a naturally aspirated 2.0 litre Z20E and, later, a 2.2 litre version. Neither
were inspiring performers.
It is rumoured that Nissan produced a handful of Silvias in the
early ’80 powered by a rotary engine based on Mazda’s 12A twin-rotor. These
rotary-powered S11 Silvias were apparently a failure and the piston engine’d
S110 Silvia was brought back into action.
One version of the S110 Silvia you probably haven’t heard about is the 240RS.
Built as a Group B rally special, the 240RS used a special version of the FJ20DE
– a FJ24D. The FJ24D employed a stroker crank (taking swept capacity to 2.4
litres), new pistons and twin side-draught carburettors – output was around
176kW. Very few S110 240RSs were built and even fewer remain intact.
Stick around for Part Two of this series – we’ll look at the modern Silvia
range, which evolved into 187kW weapons!
