The Nissan DR30 Skyline
RS The Birth of the FJ Legend!
"The DR30 Nissan RS 2000 Skyline
was born in October 1981 with the FJ20E Naturally aspirated engine fitted.
The original plan was that
this was to be a limited edition run model of which only 2000 cars
would be produced.
But many SKYLINE fan's swarmed
to NISSAN dealers and wanted to buy this hi-tech, High Performance model.
So NISSAN now saw the popularity of thie DR30 Skyline RS and it subsequently
became a JDM catalogue model.
The FJ20 engine was developed
and born in the "OGIKUBO" factory in TOKYO.
The factory is famous as
it was the birth-place of the Prince/Nissan SKYLINE and originally was
the factory of "PRINCE CAR INDUSTRIES" that was bought by NISSAN in May
of 1965.
The technology of the FJ20E
was nothing short of incredible for the early 1980's.
It featured a 4 valve
Double Overhead Camshaft head. It had been nearly 8 years since Nissan
had last used a 4 valve DOHC head, the last was the S20 straight Six from
the Skyline KPGC110 GT-R in Japan and 240K in USA.
The FJ20E engine has a reputation
for being remarkebly strong. This is not suprising as the FJ20 uses the
same both Bore Pitch as the ultra tough Nissan H20 Truck engines.
The type of valve driving
is by double-chain . Which is very strong and has high-potential at high-rev's.
The Nissan FJ20E was the
world's first production engine which featured sequential fuel injection.
Which gave the FJ20E lower fuel-consumption and unmatched performance in
its class. The Japanese Factory Power rating for the FJ20E (NA) was 150ps
and 18.5kg-m torque.

| *Early DR30 Models shared
the slatted styled grille common with other R30 Skylines. |
*Later Model DR30 Skylines
featured the Famous Iron Mask styled grille. |
But this was the early
1980's. A time in JAPAN when the major car manufacturers were competeing
in a HORSEPOWER Race!.
So in February of 1983 NISSAN
powered up the FJ20 by adding a turbo-charging system. The turbine which
they chose was a GARRET
AIR-RESEARCH T03 using a Nissan designed wastegate and without an intercooler.
The FJ20's performance grew up to 190ps and 23.0kg-m torque.
Just 1 year later in February
of 1984 the FJ20ET powered DR30 RS TURBO-C went to its final stage
of tune. The
down-sizing of the turbo-charger
to get higher-response at low-middle rev range. With the addition of an
inter-cooler and boost
pressure increase from 0.46kg/cm2(6.5psi.)
to 0.53kg/cm2(7.5psi.). Power once again grew
to 205ps and torque increased to 25.0kg-m.
NISSAN called the SKYLINE
"The
strongest SKYLINE in own history".
