This
package
gets
you
the
most
popular
and
significant
power-upgrades
that
every
twin
turbo
Q50
&
Q60
owner
should
start
with!
This
kit
will
provide
a
significant
power
increase
(300hp
models
often
see
over
a
100hp
gain!)
while
allowing
the
turbos
to
breath
more
easily.
This
package
includes...
The
AMS
Performance
Red
Alpha
intake
is
the
gold
standard
for
these
vehicles.
With
OEM
fit
and
finish,
it
properly
utilizes
the
factory
cold-air
duct,
while
providing
increased
flow
through
serviceable
filters.
For
this
RACE
package,
we
include
FULL
3"
downpipes
which
replace
both
the
upper
and
lower
factory
cats.
These
maximize
output
from
the
turbos
by
removing
the
biggest
restrictions
in
the
power
train.
Your
choice
between
3"
to
2.5",
or
full
3"
downpipes
(match
them
to
your
catback
or
Y-pipe).
Please
note
these
often
have
a
3-4
week
build
time.
Please
contact
us
for
an
ETA
if
needed,
but
remember,
you
can't
rush
perfection!
The
JB4
is
a
simple
way
of
adding
power
to
your
VR30.
By
intercepting
the
MAP
sensor
signal
to
the
ECU,
it
adjusts
the
sensor
output,
allowing
the
user
to
fine-tune
the
target
boost
as
otherwise
controlled
by
the
ECU.
In
essence,
it
tricks
the
ECU
into
providing
more
boost,
and
the
intake
&
exhaust
mods
included
with
this
kit
allow
the
turbos
to
take
advantage
of
that
increased
boost.
Optionally,
you
can
add
the
BMS
Data
Cable
or
Wireless
Mobile
Connect
kit
for
easy
adjustment
and
tuning.
We
have
observed
that
the
Z
is
extremely
prone
to
heatsoak
under
even
fairly
moderate
conditions.
When
used
in
competitive
or
demanding
situations,
the
charge
air
cooling
system
rapidly
becomes
overwhelmed,
and
the
ECU
responds
by
significantly
limiting
torque
output
(by
way
of
cutting
boost).
The
result
is
a
huge
drop
in
performance
after
only
a
few
back-to-back
WOT
pulls.
The
most
effective
solution
for
this
is
to
replace
the
tiny
factory
heat
exchanger
with
the
massive
AMS
Red
Alpha
version,
which
has
402%
more
coolant
capacity
compared
to
stock!
