AMSOIL #1 Choice
for High Performance Supra
Dear AMSOIL,
I chose AMSOIL for one reason. It is
the best bar none. A friend of mine sent
it out to a lab and had it analyzed and
compared it to a few others. AMSOIL
topped all others I chose in the past.
This was something that was important
to me because good oil is like having
good blood. It is the life in your veins.
Anytime someone wants to know what oil
I use, I tell them AMSOIL is the #1 choice.
Whether it be for a normal application
or high performance street or drag race
use, this is the oil to use.

At
first glance, the Supra appears
stock but a couple of visual clues
awaken a sense of urgent intrigue.
A shiny show-quality carbon fibre
hood and a custom-design bumper
hint of a race car and the two
gauges perched on the hood and
a NOS spray kit fastened to the
intercooler give conviction to
the growing suspicion. Twin nitrous
bottles in the trunk mounted like
missiles primed to launch seal
the verdict. A look inside the
interior reveals a bevy of gauges,
a carbon fibre dash kit, laptop,
6-point roll-cage, racing harnesses
and unique custom accessories.
The observer is convinced this
is one manic Supra.
The engine is a dizzying display for the performance-crazed: a GReddy turbo kit
(IHI RHC7 turbo from Japan), GReddy tubular manifold, GReddy Race blow-off valve,
GReddy Race external wastegate, GReddy 720 injectors, custom front mount intercooler,
a myriad of chromed parts and many unique design parts. The fastidiously clean
and meticulously organized engine makes it a hallmark of this Supra.
Supporting players in the creation of performance include a carbon fibre driveshaft,
TEC II stand-alone computer, built engine, R154 transmission with shot-peened
forks, heavy-duty bearings and RPS six-puck race clutch, TEIN HA coilovers and
custom CFX performance trailing arms.
With its former turbo, a GReddy TD-06H 20G, the Supra had 460 rear wheel horsepower
and 502 foot-pounds of torque, and achieved 12.5 at 122.48 mph trap speed without
nitrous and on street tires. A new differential and slicks will get this beast
into the 11’s and potentially into the 10’s. Now sporting a bigger turbo, it
is geared to get a minimum of 550 rear wheel horsepower without nitrous.
Although the 7M motor is capable of 500 rear wheel horsepower with stock internals
(7Mpower.com), it was decided to take the extra measure of building the engine
with JE pistons, rods and rebalanced crank. Remarkably, the power has been attained
with a stock head and stock top end.
When not in the shop, this Supra attends local and out-of-town car shows and
has snagged many trophies. Not limiting itself to import shows, its intrusion
into domestic, classic car and lowrider shows has garnered it Best Engine and
Best Performance awards. It topped the MKIII’s for the Best Engine Bay and Best
of Show Wild awards at the Supras Invade Las Vegas 2002 meet. At this event,
Sport Compact Car did a photo shoot of the car for a feature 9-page spread in
their June 2003 issue.
Even though it’s built for power and speed, its versatility is great: driven
everyday, driven far away (Las Vegas, 1300 miles one-way), a test car for new
CFX parts, a rolling billboard for CFX, a show car, and most important of all,
a (top) race car (at the track, of course). |
