Turbine
Kits:

Sports
Turbine
Kit,

Sports
Turbine
Kit,
and
GTIII-2530
Sports
Turbine
Kit.
The
lost-wax
casting
method
and
stainless
steel
construction
allow
for
a
highly
efficient,
extremely
durable
product
where
both
factors
are
needed
most.
The
port
matched
inlets
and
70mm
outlets
provide
the
perfect
balance
of
low
end
torque
by
maintaining
exhaust
velocity,
while
allowing
for
sufficient
flow
at
high
RPM
.
In-house
testing
has
shown
25
horsepower
gains
(from
520
to
545
horsepower)
between
5000
RPM
and
7000
RPM.
