Perth-WRX.com - S-Series Special Subaru Database

a lot of info on the S203/04. maybe the age of the model, perhaps the sheer numbers they built 555+600 or it signals a change of direction from STi to push these models but press information from them reaches an all time high. the previous models (maybe they did but its since long vanished from the web.) either way, its going to take a heap of time to collect all the data.

for the s203 at least, great starting point is STi's own technical article, I translated it and some words are still in japlish but don't be put off by it, very worthwhile read.....

Subaru Impreza S203 Material Description

■ S-series Basic Policy
"S Series", SUBARU STI will oversee the activities of motorsport expertise gained by the introduction of the activities of a small car project. In addition, STI rise to a strong premium brand, SUBARU is intended to drive the overall brand. Development policy, after a strong run, "悦BI owned, premium value," and, "Do not compromise on driving the car" to build. Therefore, STI is expected to "speed" to pursue the acceleration and deceleration performance, making the performance put in the chassis, the main themes and ideas that will push a strong texture of the race. In addition, each to inherit their SUBARU cars with the original taste, and not to spoil the character.

■ S203 development concept
S203, "PYUASUPOTSUSEDAN global" concept in words, the rated senior sports car that can compete with European cars, aimed at performance. Reflecting a sense of premium quality to meet the high sensitivity of the adults, not just an extension of the Subaru Impreza, tried to develop a plan developed by a separate vehicle. Instead of pursuing a performance in specific areas such as the time trial in the circuit, all the way around the world, to be faster, especially WAINDINGURODO fast, comfortable run to draw the image, the texture of the entire vehicle, including driving上GERUBEKU noted.

Design decisions during development, test track, Subaru, and the domestic circuit, and test RONGUWAINDINGURODO. The dry and wet road surface, a low-mu road, bad road, a test run at any track, a repeated or more years. Also, SUBARU World Rally Team's ace driver, Solberg PETA also joined the development and testing, chassis settings to season is reflected in his opinions.

■ S203 Vehicle Overview

Power Unit []

★ points "overwhelming sense of power over the entire exercise from the slow"
By adopting a specially designed large diameter ball bearing turbo, without sacrificing the low speed range, and a pick-up and delightful sense of overwhelming power, especially in high-speed rotation range. Focus on the transient characteristics of torque, slow rising from the flat, and to provide high torque throughout. Also, giving a balance in the inner parts of the rotation of the engine, achieving a sense of good feelings吹KE up to not show up at the specs.

● Only the main features
[Large TSUINSUKURORUTABO dedicated (Ball Bearings)
The larger the diameter turbine, that uses a ball bearing in the turbine bearings. Also, by changing the shape of the number of turbine blades, to provide a high output from the fast to slow throughout. To accelerate smoothly out of the area of rotation, and the overall ENJINFIRU get blown up high rotation region.
[EAINTEKUDAKUTO reinforced silicone rubber, EADAKUTOHOSU]
INTEKUHOSU to introduce fresh air to the turbocharger, EADAKUTOHOSU to introduce compressed air from the turbocharger inter cooler is employed to lower the rate of expansion of silicon rubber. Minimize the deformation of the hose at high load, to support the smooth introduction of air.
[Low back pressure SUPOTSUKYATARAIZA private]
While maintaining the exhaust gas purification performance, and increase efficiency and reduce exhaust air-flow resistance of the catalyst itself.
[Low back pressure muffler titanium private]
Low back pressure muffler good straight-through type. TERUENDOPAIPU drain dry EKIZOSUTOSAUNDO bass chic, lightweight titanium material φ110 high quality and emphasize the sense of a single pipe.
Only ECU]
To control the boost, the engine management functions as appropriate and TORUKUKABU.

● Take the balance of the engine parts
Piston, Connecting Rod and極少to weight fluctuations have been manually selected metric. Crank shaft, measuring the amount of unbalance of the crank were manufactured, and finished by hand adjustment. This will get the engine speed with a smooth coziness is to improve the durability of the continuous high-load operation. Therefore, the production car and engine assembly process is fully automated and a separate, dedicated and assembly process. The engine for high speed motor racing is to maintain a menu that is common sense.

By setting the chassis]

★ points "with the RAIDOKONFOTO, pursue the coziness of the adults running"
In order to achieve better than setting up the chassis with enhanced power unit, with the agility to keep the Subaru Impreza, with the information reliably grab Rhodes "I like driving all the time" feel "in quality, and intuitive driving coziness" care, incorporating the following menu.
1. Reinforced coil springs and strut damping force 4-stage adjustable inverted formula
Attitudes about the body 15mm lower to improve exercise performance, to reduce body roll by increasing the spring rate of about 50 percent of the reinforcement. The damping force is set to feel grounded and focused on the tires, and a taste of supple ride comfort. Slow decay of the area keeps rising, and fast response in the linear region, which gives the property to cover too much input. Also, you can fine-tune the damping force characteristics of the steer driving situations and preferences of four-stage variable expression.
Two. Changes in diameter RIYASUTABIRAIZA
The diameter of the rear stabilizer from φ20 to φ21 change. With improved turning round by increasing the rear roll stiffness.
Three. RIYASASUPENSHONRINKU expression PIROBORUBUSSHU
By adopting the formula RIYASASUPENSHONRINKU pyrosulfite ball, to reduce the sliding resistance, the follow-up to the surface of the suspension unit.

Tires & Wheels] [aluminum

★ point "in consideration of high-speed stability."
Adults on the positioning of the car, the exterior differentiation is not significant, the strength of expression appropriate to the performance. Front under-skirt made of dry carbon, reducing high speed lift at the front of the "zero lift" achieved. Car Rally, which employs a lighter type of carbon that is used to dry and the race car. Add a lip at the bottom of the skirt is made of rubber, and to restrict the flow of air to the lower body, doing damage control to contact the surface of the tip by changing the approach angle bumper. RIYASUPOIRA is to improve the ground at high speed RIYATAIYA, trunk-mounted in back-end-position as much as possible while the wing surface. 2-stage variable angle wing. Aerodynamic settings, considering the balance of vehicle lifts in the wind tunnel test. After a test run at high speed test track, which determines the shape. Also, S203 is fitted with front-only RAJIETAGURIRU attached to the emblem.

[Interior]

★ points "space to concentrate on driving."
Interior, the entire arrangement as the most important issues to concentrate on driving. Uniformly gray in color and all black, tight space散RANAI out. The plastic part of the instrument panel, a paint made specifically for BURAKKUSOFUTOFIRU. The speedometer is mounted on a 260km special meter. Use the red hazard button to improve visibility, and a consideration of the trailing vehicle.

■ Front bucket seats with a reclining carbon shell dry
Chassis performance and increase the power unit based on the precondition of S series, S203 is to start planning the future of the entire sheet, developed jointly with Germany's REKARO, specially developed lightweight bucket seats made of dry carbon with reclining mechanism . Lightweight dry carbon rear shell molding with new formula, adopted in the bearing surface. Combined with a special pad and skin, have a sense of tight, moderate, and comfortable to hold and fatigue long drive. Carbon shell, WRC and autoclave molding in the manufacturing process as well as a dedicated motor sport seats, and a lightweight and high strength and high rigidity. Also, many have assumed SUPOTSUDORAIBINGUSHIN back, considering the surface pressure distribution of body position, S203 is to determine the optimal shape. G DORAIBINGUPOJISHON next in a series of violent driving without any changes, and allows precise operation, Solberg also took part in the development and testing PETA has praised this sheet.
