The Big Stick Supra has loads...
The Big Stick Supra has loads of raw power, but when it comes to styling, this ain't no sleeper. The Supra's muscular silhouette is accented by a custom-fabricated sheetmetal wide-body treatment, a cool C-West carbon fiber wing, a trick Bomex front bumper and a Veilside hood.
"Walk tall and carry a big stick," a statement made famous in a movie entitled "Walking Tall" which chronicled the exploits of Bufford T. Pusser, a hard-ass, club-wielding sheriff who beat back corruption and bureaucracy in the deep South during the 1960s. On the streets of the 21st Century "Walk tall and carry a big stick," means that if you have the looks of a performance icon, you damn well better have the thrust of a performance icon. With a hard-hitting, wide-body treatment and exotic Veilside wheels, this SP Engineering-built Supra walks taller than most, but it carries a stick the size of a Sequoia, namely 700 drive-wheel hp. The Big Stick Supra is primed to beat back the bullies anywhere, any time. Amazingly, this power generation, which equates to about 805 hp at the flywheel, is realized with stock internals on 100-octane Unocal pump gas.
How'd They Do That?
This car is going where no other has gone. "The car is running 2.0 bar of boost and although this is considered excessive for a stock motor, it's holding up well. We can't really recommended it for daily use and we cannot determine how much more the stock engine will take. Until the motor blows/breaks, we'll keep boosting away! This project is a great tuning experiment and we hope to find the absolute limit of the stock 2JZ-GTE. The few problems we have encountered concerns the crank seal of all things. It seems that cars with more than 650 whp leak from this particular part. We are still looking for the fix on this one," SP's Alex Shen said.
We also quizzed Shen about the virtues of single and twin turbo applications. "Both twin and single turbo kits are able to produce similar amounts of horsepower for street applications. For street use, the twin turbos provide a better response (500-800 rpm sooner than a single kit) and therefore provides a wider power band. The single kits provide a slower response, but when you drop the hammer, they provide neck-snapping action."
The turbo system features...
The turbo system features twin HKS GT2835 ball-bearing turbos, an HKS Racing blow-off valve and a GReddy front-mounted air-to-air intercooler. Boost is regulated to 29.4 psi by a HKS EVC Pro controller and contained by an HKS metal head gasket. An HKS Vein Pressure Converter has been employed to replace the restrictive factory mass air setup. A pair of HKS 264 cams were employed to free the flow through the head while a custom downpipe and trick HKS titanium exhaust system keep the hot gases moving, once they have boosted the turbine wheel.
The 2JZ-GTE looks great, and...
The 2JZ-GTE looks great, and runs even better. SP Engineering has constructed a stout fuel system to meet the demands unleashed by a herd of 700 stampeding horses. It's an all-HKS show featuring a high-flow, in-tank pump, custom fuel rail, 680cc squirters and an adjustable fuel pressure regulator. The VPC is tag-teamed with a Graphic Control Computer (GCC) to precisely ration the fuel as the boost hits.
