We
have
successfully
applied
our
race-winning
experience
to
the
GT-R's
VR38
to
bring
you
the
paramount
in
engine
programs.
By
developing
AMS
proprietary
engine
components
we
have
engineered
the
strongest,
most
advanced
VR38
available
for
your
GT-R.
Big
Benefits,
No
Compromises
To
improve
the
output
of
your
VR38,
we
raised
the
compression
ratio
to
increase
horsepower
throughout
the
powerband.
This
increase
also
produces
more
low
end
torque
which
reduces
turbo
lag
and
improves
boost
response.
The
Perfect
Combination

Combine
that
with
the
latest
in
machine
and
assembly
practices
and
you
are
assured
only
the
best!

AMS
worked
closely
with
JE
Pistons
and
Manley
Rods
to
specially
design
engine
components
worthy
of
the
Alpha
program.
The
AMS
Extreme-Duty
pistons
feature
improved
oiling
characteristics,
Teflon
coated
skirts
for
reduced
friction
and
extra
thick
ring
lands
for
added
strength.
The
AMS
Extreme-Duty
connecting
rods
utilize
large
7/16'
ARP
2000
bolts
(22%
larger
than

for
added
durability
and
peace
of
mind.
Our
Race
Winning
Experience
Creates
Higher
Standards
To
further
improve
the
VR38
platform,
each
block
deck
is
machined
to
receive
a
copper
o-ring
to
establish
a
better
combustion
seal.
Every
Alpha
3.8
Race
Engine
is
then
precisely
balanced,
blueprinted
and
hand
assembled
to
AMS'
exacting
standards.
Before
assembly
each
block
is
checked
for
correct
dimensions,
cylinder
bore,
mains,
block
flatness,
etc.
to
guarantee
you
get
the
best
foundation
for
your
new
engine.
