it comes as no surprise to most of us, the 3rd generation
RX-7 has been known to overheat easily when driven
aggressively on the street or track. To help remedy
this, we offer the Fluidyne high Performance radiator
for the 3rd gen RX-7. using a 38mm thick core and
100% aluminum construction, it delivers a great balance
of cooling efficiency and air flow (if a radiator
is too thick, cooling air can not flow through it).
The Fluidyne radiator delivers excellent performance
at a great price. We’ve had only positive
feedback from racers and street cruisers regarding the
cooling capability and fit of this unit. Tested on
the track and on the street, this radiator is a must
for anyone that plans on using their car on the track
or driving it aggressively in hot climates, like what
we have here in Texas. Considered to be the ultimate
radiator for extreme duty, it is built for manual
trans RX-7s only!
carry a factory replacement radiator, built in Japan
and uses the same aluminum core and plastic end tanks
as the original RX-7 radiator. When replacing your
high mile engine we recommend using this radiator
or one of the aluminum units to eliminate the chance
of a split radiator tank and a blown engine. High
quality construction and an economical price make
this radiator impossible to beat as a replacement
unit for an unmodified car.

Steel braided oil metering lines are the perfect replacement for
your factory plastic units. The originals are notorious
for yellowing, cracking and breaking at the worst
time. Remember: All the oil that travels through
these lines is meant to lubricate the apex seals.
Anything leaked is cutting down on apex seal life.
Like our DOT approved brake lines, each line
is teflon inside with braided stainless steel on
the outside. Unique to our lines, the outside is
clear vinyl sleeved to avoid abrasion through hoses
and wiring near the lines. With a burst strength
of 10,000 psi, these will never fail.

Aluminum Air Separator should be the first upgrade
to the cooling system. The plastic tank that the
RX7 is originally equipped with has proven to be
inadequate again and again. The extreme underhood
temperatures combined with the pressures of the cooling
system can cause the tank to fail without warning.
The plastic tank has a tendency to split and drain
the pressurized cooling system in virtually seconds.
We all know that a HOT rotary engine is NOT a happy

Keeping the cooling system maintained is definitely a priority
to any RX owner. To regulate the temperature of the
engine, we’ve never found anything superior to the
genunie Mazda thermostat. Here it is by popular demand.

can upgrade your cooling system with the installation
of the Greddy Performance radiator cap. By increasing
the operating pressure of the system the boiling
point is also increased and the risk of overheating
is reduced. (For small filler necks only)
This upgrade is only recommendd for race cars because of the increased chance of coolant leaks.

Used in our own record setting race car, Evans High Performance is a
waterless coolant that can operate well even in a non-pressurized
system. Along with its high boiling point of 375°F,
NPG+ also features better heat transfer to minimize
detonation and pre-ignition. About 3 gallons are required
to fill an RX-7 (depending on radiator size).Note: Evans High Performance is
a pure coolant with no water added. It is not compatible
with any amount of water in the system.
High Performance Waterless Coolant - 1 gallon
When performing a conversion to Evans, it is recommended
that the system be flushed out with Evans Prep Fluid.
Evans Prep Fluid will draw any remaining water and coolant
from the system to allow the Evans to perform to its full potential.
Note: Flushing the system is not necessary if you're installing a
fresh, "dry" engine at the same time as a doing a conversion.
