With an improved airflow and a revised engine management parameters executed on a stock bottom end will significantly increase the power. The all new 1.8T is the new essence of efficiency, functionality and potential. It has a VW tunable engine and the good old Beetle's 1600cc air-cooled boxer.
If you are looking for a more turbocharged engine and planning to increase its power by half or more, then the new 1.8T is the answer you are looking out for. There are two main reasons - one that the 2.0T is still difficult for any modifications for its direct-injection technology and one-piece manifold assembly. And the second factor is that all the parts that are required for adjusting the chassis or the power level for the 1.8T model are readily available in the market from number of sources.
The 1.8T equipped with B6 has been for more than a year and half. It is a mirror image of its sister car, assembled by Stasis for the sports car revolution. These modifications can also be adapted to B5 A4 and B6 A4 versions of Audi.
The most critical modification to this project is the chassis and suspension setup. All of the parts such as springs, dampers, brakes, differential and anti-roll bars are completely interdependent. All these components are then assembled together to give maximum performance at the prescribed OEM level. Stasis has planned to provide complete solution for the different driving conditions. From hot laps of the racing tracks to the everyday street roads, this complete set works the same. The system Stasis developed concentrates on all the mechanical parts giving a perfect balance to the car which in other cases is not possible as only one or two main areas are concentrated.
Suspension modes consist of hyper co-liner coil springs wound to double-adjustable dampers in the front and single adjustable dampers in the rear. The springs and dampers are coupled with an anti-roll bar in the front and a hollow bar at the rear. For this particular arrangement, the spring rates were maintained in the middle of the rigidity medium (700 lb/in in the front, 1000 lb/in at the rear). This has improved the rigidity and performance of the car which offered a spirited driving sessions. The hydraulic charges Ohlin's dampers are compression adjustable coils that can be fine tuned for quality ride and for a perfect steering response. The whole system is run on the new 8x18 inch work emotion CR wheels which are wrapped in
Conti sport contact 2 tires.
The brakes here used are now almost found in few other cars. The system uses the Goodridge braided stainless lines and Alcon hardware. The front wheels are equipped with calipers which have four-piston mono blocks and 14-inch full floating discs. Friction is provided by SBS carbon-ceramic pads. The rear wheels are fitted with two-piece 12 inch rotors, stock calipers and Ferodo DS 2500 pads.
The engine has been over worked with the Stasis stage - III plus turbo upgrade which pushes this 1.8T into the 300 hp realm. The upgraded system contains a cast Inconel manifold, Garret GT28 turbocharger, a front-mount intercooler and supporting hardware including new fuel injectors. Along with this system, the management has been enhanced through the Stasis developed engine management software. The back pressure has been reduced with the use of high-flow-cat-black exhaust pipe.
Modifications along the driveline also include new center and rear differentials. The center differential is a Torque sensing unit, which directs the torque to either the front or rear depending on where it is most needed. Diving into a corner hard on the brakes will yield more power directed to the front. Coming out, hard on the acceleration, the balance will shift to rear wheels via the torque sensing differential unit and the new limited slip differential on the rear axle.
Though the packages are available individually, the best deal is to opt for the complete package. The top level of the package offers the Ohlin's suspension, turbo upgrade and limited slip rear differential.
The company has recently launched its "Signature collection" providing tuning options to the Audi A4 and A3 series. The signature collection comes in with two packages. The touring series comes with the increase in power, increased suspension spring rates, digressive damper valves, 19 inch forged wheels and bigger brake rotors. The challenge series takes a step further which includes the touring series along with added features of DTM aero kit, a high bias Torsion central differential, more engine power and torque. Though the package comes out at ,000 for the touring series, it is far less when compared with the products purchased individually. Guess what, you even get a 4 year/50,000 mile warranty to this package. That's something you won't see a lot of aftermarket outfits offer.
