Description
GSC
Power-Division
is
glad
to
reveal
the
newest
addition
to
our
camshaft
line,
the
GSC7043
forged
billet
S2
set
for
the
VR30
powered
Infiniti/Nissan.
This
isn’t
just
another
cam
-
lots
of
research
and
development
went
into
every
aspect
of
these
bump
sticks.
The
billet
cores
for
these
cams
are
proprietary
and
made
in
house
at
GSC.
We
developed
stronger,
lighter
cams
with
additional
fatigue
and
wear
resistance.
CNC
machining
and
grinding
gives
us
the
most
accurate
and
repeatable
camshafts
possible,
with
precision
gun
drilling
down
the
center
of
the
cam
for
oil
delivery
and
weight
reduction.
This
far
exceeds
OEM
durability
with
the
performance
GSC
Power-Division
is
world
famous
for.
Required
for
the
7043S2
cams
are
the
GSC5083
Conical
valve
springs
and
lightweight
titanium
retainers.
These
will
keep
the
valve
train
happy
up
to
9000
RPM
at
40psi
of
boost.
GSC
specifically
designed
the
valve
springs
and
retainers
for
the
high
horsepower
VR30DDTT.
