To the delight of all fans of rally sport, the heart and soul Impreza WRX have not changed. Four-cylinder horizontally-turbocharged boxer engine? There. All wheel drive? Where do without him. 6-speed gearbox and differential with electronically controlled? All locally! As a result, the biggest change in the Impreza WRX STI, in addition to the front optics connected with updated aerodynamics of the body.
For a company Blitz - manufacturer of parts for the aftermarket tuning - this is not the first experience with the WRX STI. Turbo Magazine Cover for June 2005 was decorated with a photograph of STI Blitz. At the Tokyo Motor Show this machine with two turbines K3-330R and elegant maze of silicone tubes did not leave any chance every Skyline GT-R'am, Lancer and Evolution'am Silvia'm.
Thus, by tuning Subaru Impreza WRX STI Spec C 2006, set up for street racing rather than for show, Blitz started, already having an arsenal tricks that can be applied to this model. Name «Spec C» means that the STI is already at birth was reported as the fastest car ever produced by Subaru. Ready to compete Spec C has less weight, more impressive radiators and enhanced moves, compared with the standard model STI. STI Spec C models can be identified by the air intake on the roof and dark paneling interior - neither one nor the other, you will not find on a standard STI. If you have already gathered to the local Subaru dealer, then hold your hand in bundles of cash, forced to disappoint you: Spec C is available only for the domestic Japanese market and is unlikely ever to be sold abroad.
At that time, as the STI, produced in the U.S., already equipped with a 2.5-liter engines, the Japanese are still valid 2-liter EJ20. From those two-liter engines that were equipped with American WRX from 2002 to 2005., Japanese EJ20 different dual turbo (Twin Scroll Turbo), the system AVCS (Active Valve Control System - a system control valve timing), semi-cylinders and a higher maximum speed -- 8 000 rpm. In the Japanese stock STI gives 276 hp at 6 400 rpm. and 422 Nm of torque at 4 400 rpm.
The beginning of the Blitz with the Spec C was to get rid of stock turbo system. Now supercharging carried turbokitom Blitz K3-450R # 8. Prototype turbokita includes a turbine, developed by German company KKK Turbo, exhaust pipe and a distribution pipe, veystgeyt Blitz D47D and all necessary fittings. Blitz left inlet pipe drainage system and equip them with Sonic Power Air Cleaner.
One of the side effects of horizontal engine - tied up turbocharging. Under the conditions that the exhaust ports are located on opposite sides of the engine, and only one turbine, tube exhaust manifold has a very clever twist that, in the end meet. In the initial development of Subaru, turbocharger located behind the engine and also had to use top-mount intercooler with short tubes. However, resistance to hot air at high rpm small intercooler, located on the engine - it is not the best idea.
Therefore Blitz Spec C set on a front-mount intercooler LM. Also, the car is used for cooling the radiator Blitz Racing LM with a lid pressure. With the installation of spark plugs Blitz Racing, engine tuning Spec C has been completed. Then the car was the exhaust system Blitz Nur-Spec C-Ti, fuel supply controller Blitz R-FIT, boost controller, Blitz SBC i-Color analyzer and air / fuel Blitz. As a result, we are confident 358.3 hp at 6 190 rpm. and 448 Nm of torque between 5 150 rpm.
Even when grown indicators power drive system has remained completely of stock, including the clutch and transmission, but was held a small upgrade in order to prepare to enter the track. Catabatic zhestkozakreplennye calipers Brembo (four-front and two piston rear) have heard many words of praise in his address for the high braking power and precise modulation. Blitz added on my own brake pads - Blitz Pagid RS4-2 front and Blitz MR-3 from behind. New tires - Dunlop Direzza Sport Z1 configuration 245/40/18. By itself, a different staffing suspension Spec C has been replaced by a rack assembly Blitz Damper ZR with a spring stiffness of 12 kg / mm front and 8 kg / mm rear, fully adjustable dampers, adjustable height adjustable angle clearance and the collapse of the front wheels.
Externally, the STI represents a typical stritkar with a full set of aerodynamic Pribluda. And all this not only for the species - the car was actually allowed to compete in the class Group N. Established Aerodynamics STI Spec C includes the air intake on the hood that directs air to the intercooler, side "skirt" the front "lip, rear diffuser, air intake on the roof and spoiler. Only addition from the Blitz became front spoiler Flex.
Following the original recipe Subaru, Blitz made the tuning Impreza WRX STi Spec C in accordance with the original design. No super-acoustics, no fiberglass and other unnecessary junk. Simply tighten the bolts and add extra power and speed.
