A side effect of turbocharging
is an increase in air temperature going into the engine.
When the turbo creates boost and compresses the intake
air, it’s far too hot for
maximum power. To overcome this problem, an intercooler
(which utilizes a design similar to a radiator) is
typically used. The intercooler is positioned between
the turbo and engine and all the hot intake air that
comes out of the turbo is cooled by the intercooler
before it goes into the engine. This makes the intake
charge more dense which equates to more power and helps
to prevent detonation.
The Efini Turbo Piping Upgrade kit for the twin turbo system
eliminates the last plastic tube and rubber joint which
connect the turbo outlet with the intercooler inlet piping.
These updated componentes were developed for the 96-02 Rx7,
as a result of Mazda's efforts to increase power output. The all-aluminum
design eliminates the leak prone, rubber joint, while the updateted Y-pipe
design improves air flow and increases power.
The kit includes the gaskets, o-ring and nuts that are necessary for installation.

The RX-7 already has
a small intercooler from the factory that is capable
of cooling the intake air sufficiently at stock boost
level and moderate driving conditions. Once you’ve increased the engine’s
efficiency with exhaust and intake, an upgraded intercooler
will be required to move up to the next level of performance
without damaging the motor. For the performance enthusiast
looking for the ultimate in performance, GReddy offers
an upgraded intercooler that exactly replaces the stock
intercooler with a much larger, much more efficient
intercooler. This kit is perfect for those that are
looking for a safe way to gain more power while protecting
engine life.
