Tuning Stage 5 for Speedster Turbo: 365PS 520Nm

Developed in autumn / winter 2010, stage 5 is our latest evolution to raise the power of your Opel Speedster Turbo.
The "heart" of stage 5 is our new developed K16-technology based NextGen 2 Turbocharger, which comes with the newest generation of turbine- and compressoer wheels with cutback geometry.

Of course, this required several environment-modifications as well:
- a watercooled chargecooler system is used instead of the aircooled intercooler of previous stages for another significant drop of intake-air temperatures.
- Larger fuel injectors are added to match the higher specific fuel consumption
- An oil cooler kit is added to keep oil-temperatures in a healthy range
- balancing shafts are removed to raise agility of the engine and, at the same time, this raises the oil reservoir by 0.75 liter
- a full 3" turboback exhaust system with 200 cpsi race-cat for maximum reduction of exhaust-conterpressure replaces the OEM exhaust.
- a new developed NG2 Airbox Kit is used to support the NextGen2 charger. This kit is developed to carry an 80mm AMM, which is also part of the stage 5 kit
- an external blow-off kit is also included to match NextGen2 requirements
- ECU remap is precisely new built to match stage 5 specifications.

The NextGen2 turbocharger (which is part of this kit) is built on base of your OEM turbocharger. We require your OEM charger in advance to convert it to NextGen2!
Any Z20LET / Z20LER / Z20LEL / Z20LEH OEM charger can be used for this NextGen conversion.
The charger you send to us for modification may also have damage of the rotor assembly or charger housing. Manifold, and wastegate actuator must be in reworkable condition (not warped, cracked or otherwise damaged).
Also you will need to send your OEM intake elbow to us in order to get the blow-off connector integrated.
All other stage 5 kit-components are new.

Our central point of interest was to reach a homogeneous inflating of the power without disturbing torque peaks and stable power at higher revs - also at higher outside temperatures.
High power with maximum driveability in all environments was, what we were looking for. You can be sure, that we have found it.
Spontanity and agility of the engine are again significantly raised.
The maximum power raises from 200 to 365 PS, maximum torque from 250 to 520 Nm.
Rev. limiter is raised to 7200 1/min (can be set to any other value on customers request)
The usage of high octane fuel (98 octane or better) is strictly recommended for Stage 5 tuned cars!

IMPORTANT - fair terms of upgrade:
Due to the fact that all our tuning stages are based on each other, you can upgrade your car to a higher stage at any time.
Please call or email us for any upgrade purposes.
 
For installation of the remap you can send us your ECU or visit us with your car.
The costs for software installation are allready contained in the price of the kit.
Fitting of all stage 5 components and individual software calibration on our dyno can be done by us at seperate charge (see above).

Please note:
Stage 5 is a pure power upgrade kit. It will require several reinforcements at engine base and peripherals as well.
A sports clutch and a stronger fuel pump are required under all circumstands, a reinforced engine base with steel rods and forged pistons is strictly recommended as well.
