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.

| Name: Duane Stephens Location: Surrey, BC, Canada Car: 1989 Toyota Supra Color: White |
Baseline Dyno Figures (Stock): Horsepower: 665HP Torque: 660 (Rated @ The Wheels) 1/4 Mile: 11.00 @130.27 |
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).
