The Rx-7 Turbo
PLEASE remember that increasing the boost on ANY engine decreases the life of the engine,
and severely decreases the "safety zone" between safe running conditions and terminal engine
death. We continue to receive MANY calls from customers that have added numerous "bells and
whistles" to their Turbos, ran fine for a few thousand miles, then hand-grenaded the engine.
The cause is usually detonation from too much boost pressure in relation to fuel mixture,
temperature (outside air, intake air, and engine bay temperature), and ignition timing.
The result is usually broken apex seals, that then take out the rotors and rotor housings
with them. Whatever "package" has been added may eventually be "tuned" right, but engine
damage could easily have happened during the "tweaking" stages, and will not show up
until a few thousand miles later.
Intercooler Upgrade Kit
An Intercooler works to increase horsepower not by increasing boost, but by lowering the
temperature of the intake air. The colder the air is, the more densely packed its molecules
are. Therefore, more air can fit in the same combustion chamber volume. Additionally, by lowering
the temperature of combustion gasses, engine wear is reduced and longevity increased.
The stock intercooler is designed to make the engine run safely at the factory set boost level.
The intercooler upgrade kit replaces this stock intercooler and reduces the temperature to well
below that safety margin. The upgrade kit alone makes a very noticeable horsepower increase,
while its increased safety margin allows for further modification of boost pressures.
