Performance Kit Audi/Porsche RS2 Step, 350–360 PS – 450 Nm, 3B / RR (all with distributor ignition) Plug & Play 20V 3B Turbos. Incl. Injectors and ECU. For NON-REINFORCED engines

The 5inline Motorsport RS2 Step performance kit elevates your Audi/Porsche 20V Turbo, specifically with 3B or RR distributor ignition, to around 350–360 PS and approx. 450 Nm of torque. The tune is developed exclusively for non-reinforced standard engines — torque is deliberately limited to safeguard durability even with standard con-rods and pistons.

The kit includes:

• Matched and calibrated fuel injectors

• Optimised ECU (configured for distributor ignition / 3B variant)
  

• Cast exhaust manifold

• Original RS2 turbocharger

Plug & Play installation in all 20V Turbo vehicles without modification to the ignition system

Important note:
Your vehicle's technical condition must be sound. A good general state of engine and periphery is fundamental for safe operation and the targeted performance. Wear parts, fuel supply, and cooling should be checked and serviced regularly to avoid damage and unlock the kit's full potential.

Recommended (but not strictly required) upgrades for optimal operation:

• Intercooler: Larger and more efficient solutions improve charge and combustion air temperatures — boosting thermal capacity, power delivery, and the number of back-to-back full-throttle runs at summer temperatures.

• Downpipe/catalytic converter: An optimised exhaust path reduces back-pressure and exhaust temperatures, relieves the turbocharger, and can increase engine power.

• Sport exhaust system: Provides reduced back-pressure, a sportier sound, and can improve driving dynamics.

• Fresh spark plugs

Your benefits with the 5inline Motorsport RS2 Step kit:

• Plug & Play upgrade without complex conversion

• Maximum performance for distributor ignition engines (3B/RR)

• Torque limiting protects standard components

• Everything from one source — injectors and ECU matched and tested

• Individualised solutions and advice backed by motorsport expertise

• Optional: further upgrades and dyno tune for maximum precision

Note:
For best performance and durability of the RS2 Step, regular maintenance of all relevant components — fuel system, oil system, and engine cooling — is strongly recommended.

Choose bespoke performance and street-friendliness, specifically tuned for the legendary five-cylinder turbo engines with distributor ignition — and benefit from the experience and quality of 5inline Motorsport.
